Update Log for the Vulkan-Docs repository on Github. Updates are in reverse
|
|
chronological order starting with the latest public release.
|
|
|
|
This summarizes the periodic public updates, not individual commits. Updates
|
|
on Github are done as single large patches at the release point, collecting
|
|
together the resolution of many Khronos internal issues, along with any
|
|
public pull requests that have been accepted.
|
|
|
|
-----------------------------------------------------
|
|
|
|
Change log for October 28, 2018 Vulkan 1.1.90 spec update:
|
|
|
|
* Update release number to 90.
|
|
|
|
Public Issues:
|
|
|
|
* Tag flink:vkQueueWaitIdle as `externsync` in `vk.xml` (public pull
|
|
request 815).
|
|
* Update README (public pull request 834).
|
|
* `VK_NV_framebuffer_mixed_samples` and `VK_AMD_mixed_attachment_samples`
|
|
had confusing and contradictory valid usage statements when read in the
|
|
all-extensions spec build. Change them to explicitly mention which
|
|
extension each is for (public issue Vulkan-ValidationLayers/issues/353).
|
|
|
|
Internal Issues:
|
|
|
|
* Update `COPYING.md` to clarify how externally generated Vulkan
|
|
Specifications (for translations, annotations, or other reasons) must be
|
|
copyrighted, and acknowledge the Exception Clause on the `vk.xml`
|
|
license (internal issue 1079).
|
|
* Specify that flink:vkGetPhysicalDeviceImageFormatProperties may: return
|
|
pname:maxMipLevels 1 if the format is ycbcr (internal issue 1361).
|
|
* Clarify previously underspecified language for
|
|
flink:vkCmdPushConstants::pname:pStageFlags regarding use of push
|
|
constants across multiple pipelines (internal issue 1403).
|
|
* Fix typo in XML/headers for
|
|
ename:VK_STRUCTURE_TYPE_IMAGE_DRM_FORMAT_MODIFIER_EXPLICIT_CREATE_INFO_EXT,
|
|
which was previously
|
|
etext:VK_STRUCTURE_TYPE_IMAGE_EXCPLICIT_DRM_FORMAT_MODIFIER_CREATE_INFO_EXT
|
|
(internal issue 1428).
|
|
* Fix markup of equations that were sporadically breaking the
|
|
`optimize-pdf` step of PDF generation, due (apparently) to inconsistent
|
|
treatment of unwrapped multicharacter terms by different LaTeX parsers
|
|
(internal issue 1435).
|
|
* For the <<memory-model-synchronizes-with synchronizes-with>> memory
|
|
model relation cases involving a release barrier plus relaxed atomic
|
|
write, treat the atomic as if it were a release atomic and allow the
|
|
acquire side to read from its hypothetical release sequence. This is
|
|
more consistent with how C++ defines synchronization for release fences
|
|
(internal issue cross-api/memory-model#72).
|
|
* Minor editorial changes to the <<memory-model, memory model>> appendix
|
|
based on external feedback.
|
|
|
|
-----------------------------------------------------
|
|
|
|
Change log for October 21, 2018 Vulkan 1.1.89 spec update:
|
|
|
|
* Update release number to 89.
|
|
|
|
Public Issues:
|
|
|
|
* Clarify the reference to <<features-limits-mipmapPrecisionBits, mipmap
|
|
precision bits>> in the <<textures-image-level-selection, Image Level(s)
|
|
Selection>> section (public issue 660).
|
|
* Update <<debugging-object-types,VkObjectType and Vulkan Handle
|
|
Relationship>> table with missing types (public pull request 820).
|
|
* Miscellaneous minor markup cleanup (public pull request 822).
|
|
* Fix copy/paste bugs in the description of how implicit
|
|
availability/visibility operations for atomics/barriers are ordered in
|
|
the <<memory-model-availability-visibility-semantics, Availability and
|
|
Visibility Semantics>> section (public issue 823).
|
|
* Add missing shading_rate_image bit from mesh pipeline list in the
|
|
<<synchronization-pipeline-stages-types>> list (public issue 824).
|
|
|
|
Internal Issues:
|
|
|
|
* Clarify that only statically used members of a push constant block need
|
|
to be in the push constant range, and stop referring to block members as
|
|
"`variables`" in the <<interfaces-resources-pushconst, Push Constant
|
|
Interface>> section. This is related to
|
|
https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/340
|
|
(internal issue 1401).
|
|
* Clarify interaction between flink:vkCmdSetDeviceMask and render pass
|
|
control commands in the slink:VkDeviceGroupRenderPassBeginInfo section
|
|
(internal issue 1416).
|
|
* Miscellaneous minor markup cleanup.
|
|
* Remove types defined by `"disabled"` extensions from
|
|
validextensionstructs in the XML processing scripts, so downstream code
|
|
generators don't emit them.
|
|
|
|
-----------------------------------------------------
|
|
|
|
Change log for October 13, 2018 Vulkan 1.1.88 spec update:
|
|
|
|
* Update release number to 88.
|
|
|
|
Public Issues:
|
|
|
|
* Make clear that
|
|
tname:PFN_vkDebugUtilsMessengerCallbackEXT::pname:messageTypes is a
|
|
bitmask, and correct a typo in the spelling of
|
|
slink:VkDebugUtilsMessengerCreateInfoEXT.txt::pname:messageType (public
|
|
pull request 800).
|
|
* Make an ABI-compatible change of the type of
|
|
slink:VkPhysicalDeviceDriverPropertiesKHR::pname:driverID to use the new
|
|
elink:VkDriverIdKHR type (public issue 811).
|
|
|
|
Internal Issues:
|
|
|
|
* Clarify for the <<features-features-shaderStorageImageExtendedFormats>>
|
|
feature and in the <<spirvenv-capabilities-table>> that the feature
|
|
means that all of the formats are supported, and that otherwise the
|
|
features can be queried per-format (internal issue 1273).
|
|
* Clarified interactions of `VK_EXT_external_memory_host` with host cache
|
|
management commands and structures flink:vkMapMemory,
|
|
flink:vkFlushMappedMemoryRanges, slink:VkMappedMemoryRange, and
|
|
flink:vkUnmapMemory using the new glossary term "`Host Mapped Device
|
|
Memory`" (internal issue 1385).
|
|
* Update the language for flink:vkCreateViSurfaceNN.txt describing the
|
|
pname:currentExtent of a VI surface to more accurately reflect current
|
|
capabilities, replacing "`undefined`" with more explicit behavior
|
|
(internal issue 1410).
|
|
|
|
New Extensions:
|
|
|
|
* `VK_EXT_calibrated_timestamps`
|
|
* `VK_EXT_image_drm_format_modifier` (this extension was previously
|
|
disabled in vk.xml, and has now been enabled after some changes to fix
|
|
performance issues).
|
|
* `VK_EXT_pci_bus_info`
|
|
* `VK_EXT_transform_feedback`
|
|
* `VK_GOOGLE_hlsl_functionality1`, exposing support for
|
|
`SPV_GOOGLE_hlsl_functionality1`.
|
|
* `VK_GOOGLE_decorate_string`, exposing support for
|
|
`SPV_GOOGLE_decorate_string`.
|
|
|
|
-----------------------------------------------------
|
|
|
|
Change log for October 7, 2018 Vulkan 1.1.87 spec update:
|
|
|
|
* Update release number to 87.
|
|
|
|
Public Issues:
|
|
|
|
* Merge flink:vkCmdPipelineBarrier self-dependency barrier VUs referring
|
|
to the same subpass dependency (public pull request 756).
|
|
* Describe default value of `"optional"` attribute in the registry schema
|
|
document (public issue 769)
|
|
* Fix links in <<VK_NVX_raytracing>> extension (public pull request 805).
|
|
* Mark the <<VK_KHR_mir_surface>> extension obsolete (see public issue 814
|
|
- does not close this, however).
|
|
* Fix missing endif in Image Creation block (public issue 817).
|
|
|
|
Internal Issues:
|
|
|
|
* Clarify that the compressed texture formats corresponding to
|
|
<<features-features-textureCompressionETC2>>,
|
|
<<features-features-textureCompressionASTC_LDR>>, and
|
|
<<features-features-textureCompressionBC>> is not contingent on the
|
|
feature bits, and may be supported even if the features are not enabled
|
|
(internal issue 663).
|
|
* Clarify that code:FragStencilRefEXT is output only in the
|
|
<<interfaces-builtin-variables, Built-In Variables>> section (internal
|
|
issue 1173).
|
|
* Identify and correct many overly-aggressive uses of "`undefined`", and
|
|
narrow them down, where straightforward to do so. Mark such resolved
|
|
uses of "`undefined`" with the custom undefined: macro. Add a new
|
|
<<writing-undefined, Describing Undefined Behavior>> section (internal
|
|
issue 1267).
|
|
* Don't require code:inline_uniform_block descriptors to be populated
|
|
before use in the flink:vkAllocateDescriptorSets section (internal issue
|
|
1380).
|
|
* Allow suppressing inline SVG images by controlling this with an
|
|
attribute set in the Makefile, rather than the explicit [%inline]
|
|
directive (internal issue 1391).
|
|
* Mark 'Khronos' as a registered trademark in several places, now that it
|
|
is one.
|
|
* Fix typo in the <<VK_KHR_shader_atomic_int64>> appendix using the GLSL
|
|
naming of the compare exchange op when referring to the SPIR-V op.
|
|
* Specify in the flink:vkGetPhysicalDeviceQueueFamilyProperties section
|
|
that all implementations must support at least one queue family, and
|
|
that every queue family must contain at least one queue.
|
|
* Make slink:VkPipelineDynamicStateCreateInfo::pname:dynamicStateCount,
|
|
slink:VkSampleLocationsInfoEXT::pname:sampleLocationsPerPixel, and
|
|
slink:VkSampleLocationsInfoEXT::pname:sampleLocationsCount optional, to
|
|
fix bogus implicit valid usage checks that were causing failures in the
|
|
conformance tests.
|
|
* Fix vendor tag in reserved extension 237 constants. Does not affect
|
|
anything since it's just a placeholder, but this should avoid further
|
|
comments.
|
|
* Minor markup fixes in some extension appendices.
|
|
|
|
New Extensions:
|
|
|
|
* `<<VK_FUCHSIA_imagepipe_surface>>`
|
|

|
|
|
Change log for September 29, 2018 Vulkan 1.1.86 spec update:
|
|
|
|
* Update release number to 86.
|
|
|
|
Internal Issues:
|
|
|
|
* Add new <<resources-image-creation-limits, Image Creation Limits>>
|
|
section and reference that from valid usage statements, reducing
|
|
combinatorial complexity of extension-dependent VUs. Also fixes some
|
|
underspecified limits (such as pname:maxMipLevels) in the VUs for
|
|
slink:VkImageCreateInfo when
|
|
slink:VkExternalMemoryImageCreateInfo::pname:externalMemoryHandles
|
|
contains multiple bits, and fixes incorrectly (and underspecified)
|
|
limits when an Android external format is used (internal issue 1370).
|
|
* Remove unused "`Fragment Area Granularity`" glossary entry accidentally
|
|
introduced in the 1.1.85 update.
|
|
|
|
New Extensions:
|
|
|
|
* `VK_KHR_driver_properties`
|
|
* `VK_KHR_shader_atomic_int64`
|
|
* The specification sources contain text for another extension,
|
|
`VK_EXT_image_drm_format_modifier`, but this extension is not yet
|
|
complete, and is marked disabled in `vk.xml`. The extension will be
|
|
enabled, and become part of the spec, only when the authors decide it is
|
|
ready.
|
|
|

|
|
|

section (internal issue 1346).
|
|
* Revert extension metadoc generator warning about name mismatches to a

images and image views, and rewrite valid usage statements to reference
|
|
these sections instead of duplicating language (internal issue 1310).

Change log for July 1, 2018 Vulkan 1.1.79 spec update:
|
|
|
|
* Update release number to 79.
|
|
|
|
Public Issues:
|
|
|
|
* Add a note to the <<features-required-format-support, Required Format
|
|
Support>> section clarifying that the required formats don't depend on
|
|
the used flags (public issue 671).
|
|
* Add a valid usage statement for flink:vkUpdateDescriptors that was
|
|
previously described for slink:VkImageSubresourceRange, but not as a
|
|
valid usage statement (public issue 713).
|
|
* Modify implicit valid usage generator script to not emit 'must: not be
|
|
0' for a parameter that is a pointer to a flags field, such as
|
|
pname:pPeerMemoryFeatures (public issue 729).
|
|
|
|
Internal Issues:
|
|
|
|
* Add definitions of "`obsoleted`" and "`deprecated`", and modify the
|
|
definition of "`promoted`" in the <<glossary, Glossary>> (internal issue
|
|
988).
|
|
* Add language for integer texel output conversions (the conversion is
|
|
undefined) to the <<textures-output-format-conversion]] Texel Output
|
|
Format Conversion>> section. Simplify and clarify the floating-point
|
|
conversion language in the <<fundamentals-general, General
|
|
Requirements>> section and the new <<fundamentals-fp-conversion,
|
|
Floating-Point Format Conversions>> section, and remove obsolete
|
|
language in the format-specific floating-point sections (internal issue
|
|
1275).
|
|
* Add the elink:VkVendorId enumerated type to the Vulkan API / XML /
|
|
header, so reserved Khronos vendor IDs can be referred to symbolically
|
|
by clients. Note that only Khronos vendor IDs (e.g. non-PCI vendor IDs)
|
|
are defined (internal issue 1299).
|
|
* Fix typo in the <<fig-non-strict-lines, Non strict lines>> table
|
|
(internal issue 1315).
|
|
* Clean up and simplify the
|
|
<<features-formats-requiring-sampler-ycbcr-conversion, YCbCr format
|
|
properties>> table and use symbols consistently with other tables. Add a
|
|
column for the number of planes.
|
|
* Add code:Float16 to the <<spirvenv-capabilities-table, List of optional
|
|
SPIR-V capabilities>> for the `VK_AMD_gpu_shader_half_float` extension.

Change log for June 18, 2018 Vulkan 1.1.78 spec update:
|
|
|
|
* Update release number to 78.
|
|
|
|
Public Issues:
|
|
|
|
* Change markup so parameter descriptions include links to structures,
|
|
instead of just their names (public issue 697).
|
|
* Resume publishing updated Vulkan 1.0 + KHR extensions and Vulkan 1.0 +
|
|
all extensions versions of the specification (public issue 722).
|
|
* Reapply fixes from public pull request 698 for
|
|
`VK_ANDROID_external_memory_android_hardware_buffer`, which accidentally
|
|
were reverted at some point (public pull request 724).
|
|
* Fix undefined format valid usage statements for slink:VkImageCreateInfo
|
|
in the presence of the
|
|
`VK_ANDROID_external_memory_android_hardware_buffer` extension (public
|
|
pull request 725).
|
|
* Miscellaneous markup consistency fixes (public pull request 728).
|
|
|
|
Internal Issues:
|
|
|
|
* When building specifications containing vendor extensions, add terms to
|
|
the Khronos spec copyright specifying that the result is not a ratified
|
|
specification (internal issue 739).
|
|
* Change the value of the
|
|
pname:maxDescriptorSetUpdateAfterBindUniformBuffers minimum limit to 72
|
|
(6 times pname:maxPerStageDescriptorUpdateAfterBindUniformBuffers) in
|
|
the <<features-limits-required, Required Limits>> table (internal issue
|
|
1300).
|
|
|
|
Other Issues:
|
|
|
|
* Fix link to resource image view compatibility table in the valid usage
|
|
statements for slink:VkImageFormatListCreateInfoKHR (internal pull
|
|
request 2711).

|
Change log for June 10, 2018 Vulkan 1.1.77 spec update:
|
|
|
|
* Update release number to 77.
|
|
|
|
Public Issues:
|
|
|
|
* Remove redundant asciidoctor ifdef in slink:VkDeviceCreateInfo valid
|
|
usage statement (public pull request 718).
|
|
|
|
Internal Issues:
|
|
|
|
* Require that the returned slink:VkMemoryRequirements::pname:alignment
|
|
reflect the minimum alignment requirements for the buffer's usages, and
|
|
make dynamic offset alignment valid usage more explicit for
|
|
flink:vkBindBufferMemory and flink:vkCmdBindDescriptorSets (internal
|
|
issue 1170).
|
|
* Explicitly state that objects of type code:OpTypeImage,
|
|
code:OpTypeSampler, and code:OpTypeSampledImage must not be stored to in
|
|
the <<spirvenv-module-validation, Validation Rules within a Module>>
|
|
section (internal issue 1262).
|
|
* Clarify rules about validating descriptor set/binding against storage
|
|
class and descriptor type in the <<spirvenv-module-validation,
|
|
Validation Rules within a Module>> section, and add an anchor for and
|
|
references to the <<interfaces-resources-storage-class-correspondence,
|
|
Shader Resource and Storage Class Correspondence>> table (internal issue
|
|
1266).
|
|
* Use correct spelling of SPIR-V decoration code:NonWritable in several
|
|
places (internal issue 1298).
|
|
|
|
Other Issues:
|
|
|
|
* Update specification links to files in the old
|
|
KhronosGroup/Vulkan-LoaderAndValidationLayers repository with
|
|
corresponding links into the new repositories that replace it.
|
|
* Move validity requirement for slink:VkSamplerCreateInfo into the valid
|
|
usage block instead of the body text, and give it a VUID.
|
|
* Use the full name of the "`style guide`" in a reference in the
|
|
description of slink:vkGetPhysicalDeviceProperties, update the
|
|
<<vulkan-styleguide, link to that document>>, and use the full name
|
|
in the registry index page.

Change log for May 25, 2018 Vulkan 1.1.76 spec update:
|
|
|
|
* Update release number to 76.
|
|
|
|
Internal Issues:
|
|
|
|
* Add an exception clause to the license on `vk.xml`, enabling its use
|
|
with GPL-based projects (internal issue 1017).
|
|
* Remove the generated `vulkan_ext.[ch]` files, which are no longer
|
|
supported. Add `src/ext_loader/README.md` explaining why, and update
|
|
files in `xml/` to not generate them by default (internal issue 1268)
|
|
|
|
Other Issues:
|
|
|
|
* Fix typos in valid usage statements for the
|
|
ftext:vkDrawIndexedIndirectCount* commands, replacing
|
|
sizeof(VkDrawIndirectComment) with sizeof(VkDrawIndexedIndirectCommand).
|
|
* Modify the <<spirvenv-module-validation, Validation Rules within a
|
|
Module>> section to require code:NonReadable or code:NonWriteable in
|
|
SPIR-V code for images with an image format of code:Unknown if one of
|
|
the requisite code:shaderImageReadWithoutFormat or
|
|
code:shaderImageWriteWithoutFormat features is disabled.
|
|
|
|
New Extensions:
|
|
|
|
* `VK_KHR_get_display_properties2`
|
|
* `VK_KHR_draw_indirect_count`
|

|
Change log for May 16, 2018 Vulkan 1.1.75 spec update:
|
|
|
|
* Update release number to 75.
|
|
|
|
Github Issues:
|
|
|
|
* Use Github handles (e.g. @handle) for contact information in vk.xml,
|
|
when available (partial fix for public issue 630).
|
|
* Add size invariance guarantee to slink:VkMemoryRequirements for
|
|
buffer/image memory requirements (public issue 661).
|
|
* Correct scope (conditional constructs) in valid usage statement for
|
|
slink:VkBindImageMemoryInfo (public pull request 684).
|
|
* Clean up minor markup issues and typos in the
|
|
`VK_ANDROID_external_memory_android_hardware_buffer` extension appendix
|
|
(public pull request 698).
|
|
* Modify registry processing script to avoid irrelevant warnings of benign
|
|
enumerant redefinitions (public pull request 705).
|
|
* Fix some duplicate words and some misspelled "`stagess`" (public pull
|
|
request 712)
|
|
|
|
Internal Issues:
|
|
|
|
* Enable continuous integration tests on the internal Khronos gitlab
|
|
server by adding a .gitlab-ci.yml file. Note: this does not implement CI
|
|
on the public Github repository (internal issue 408).
|
|
* Add link from description of depth clamping in the <<fragops-depth,
|
|
depth test>> section to the
|
|
slink:VkPipelineRasterizationStateCreateInfo::pname:depthClampEnable
|
|
parameter which enables it, making it easily searchable / findable
|
|
(internal issue 1125).
|
|
* Clarify that arrays of arrays of descriptors are not allowed in the
|
|
<<interfaces-resources-descset, Descriptor Set Interface>> and
|
|
<<interfaces-resources-setandbinding, DescriptorSet and Binding
|
|
Assignment>> sections (internal issue 1192).
|
|
* Comment out some redundant nested asciidoctor conditionals in the
|
|
slink:VkImageViewCreateInfo valid usage block, and explain in all cases
|
|
why the redundant conditional exist and are commented out (internal
|
|
issue 1231).
|
|
* Move a valid usage statement from slink:VkCommandPoolCreateInfo to the
|
|
parent flink:vkCreateCommandPool, where the device queue is known
|
|
(internal issue 1233).
|
|
* Add new slink:VkBaseInStructure and slink:VkBaseOutStructure types which
|
|
can be used by extensions and implementations for handling Vulkan
|
|
sType/pNext style structures in a more generic way (internal issue
|
|
1265).
|
|
* Clarify that
|
|
slink:VkAndroidHardwareBufferFormatPropertiesANDROID::pname:formatFeatures
|
|
only applies to external-format images. Add references to this in valid
|
|
usage statements that previously only referred to
|
|
slink:VkFormatProperties (internal issue 1244).
|
|
* Fix the description of elink:VkPipelineCreateFlagBits enumerant
|
|
ename:VK_PIPELINE_CREATE_VIEW_INDEX_FROM_DEVICE_INDEX_BIT to match the
|
|
name (internal issue 1279).
|
|
* Add a NOTE to the <<interfaces-resources-setandbinding, DescriptorSet
|
|
and Binding Assignment>> section making it clear that variables sharing
|
|
a storage class may use identical descriptor set and bindings.
|
|
Specifically state the sometimes misunderstood ability to have one or
|
|
more differently typed image descriptors sharing a descriptor set and
|
|
binding (internal SPIR-V issue 264).
|
|
* Make DynamicIndexing features and capabilities also control the
|
|
uniformity of the descriptor used in memory access instructions in the
|
|
<<interfaces-resources-descset, Descriptor Set Interface>> section. This
|
|
makes them also apply to variable_pointer usage, which can bypass the
|
|
array indexing operation (internal SPIR-V issue 289).
|
|
|
|
Other Issues:
|
|
|
|
* Correct flink:vkCmdBlitImage limitations on cubic blits to be 2D only,
|
|
not 3D.
|
|
* Update valid usage statements for slink:VkRenderPassCreateInfo and
|
|
slink:VkInputAttachmentAspectReference.
|
|
* Move YCbCr-related VU statements from slink:VkDescriptorImageInfo to
|
|
slink:VkWriteDescriptorSet, where all needed information is known, and
|
|
remove redundant statements.
|
|
* Move SPIR-V restriction that images be of either sampled or storage
|
|
types from the <<interfaces-resources-descset, Descriptor Set
|
|
Interface>> section to the <<spirvenv-module-validation, Validation
|
|
Rules within a Module>> section of the SPIR-V appendix.

Change log for April 21, 2018 Vulkan 1.1.74 spec update:
|
|
|
|
* Update release number to 74.
|
|
|
|
Github Issues:
|
|
|
|
* Clarify which buffer locations are accessed in
|
|
flink:vkCmdCopyBufferToImage valid usage statements (public issue 676).
|
|
* Refine description of <<extended-functionality-extensions-dependencies,
|
|
extension dependencies>>, related NOTE in the
|
|
<<extended-functionality-extensions, Extensions>> section, and
|
|
"`Required Extensions`" glossary term (public pull request 693).
|
|
* Add support for specifying required Vulkan core version in `vk.xml` and
|
|
the extension metadoc generator (public issue 696).
|
|
* Update .gitignore for directory reorganization (public pull request
|
|
699).
|
|
* Fix typo (public pull request 703).
|
|
|
|
Internal Issues:
|
|
|
|
* Update valid usage of slink:VkClearRect::pname:layerCount (internal
|
|
issue 1241).
|
|
|
|
Other Issues:
|
|
|
|
* Fix typo in <<NV_geometry_shader_passthrough>> issues list.
|
|
|
|
-----------------------------------------------------
|
|
|
|
Change log for April 15, 2018 Vulkan 1.1.73 spec update:
|
|
|
|
* Update release number to 73.
|
|
|
|
Github Issues:
|
|
|
|
* Refine swapchain association with surface for slink:VkSwapchainKHR, with
|
|
matching valid usage statements for slink:VkSwapchainCreateInfoKHR and
|
|
discussion following the <<swapchain-wsi-image-create-info>> table
|
|
(public issue 637).
|
|
* Re-remove several valid usage statements from slink:VkImageCreateInfo
|
|
that had previously been removed at the time that
|
|
ename:VK_IMAGE_CREATE_EXTENDED_USAGE_BIT was introduced. These
|
|
statements had incorrectly been restored due to an glitch while merging
|
|
from the old `1.0` branch to the current `master` branch (public issue
|
|
683).
|
|
|
|
Internal Issues:
|
|
|
|
* Fix reference page generation and configure build to generate reference
|
|
pages 1.1 with all extensions, rather than core only, as was the case
|
|
for the 1.0 ref pages (internal issues 484, 1056, 1205).
|
|
* Require that
|
|
slink:VkMemoryDedicatedRequirements::pname:prefersDedicateAllocation is
|
|
ename:VK_TRUE when
|
|
slink:VkMemoryDedicatedRequirements::pname:requiresDedicateAllocation is
|
|
ename:VK_TRUE (internal issue 1222).
|
|
* Fix Ruby extension code so `diff_html` Makefile target works (internal
|
|
issue 1230).
|
|
* Update `genRelease` script to generate 1.1 + all extensions reference
|
|
pages - but not the single-page HTML / PDF versions, which are even
|
|
larger than the API spec (internal issue 1245).
|
|
|
|
Other Issues:
|
|
|
|
* Add missing attributes to `vk.xml` for `VK_ANDROID_native_buffer`.
|
|
* Specify that the slink:VkAttachmentDescription::pname:format member is
|
|
the format of the image *view* that will be used for the attachment.
|
|
* Use core sname:VkPhysicalDeviceFeatures2 in the `structextends` `vk.xml`
|
|
attribute for sname:VkPhysicalDeviceDescriptorIndexingFeaturesEXT and
|
|
sname:VkPhysicalDeviceDescriptorIndexingPropertiesEXT, rather than the
|
|
KHR equivalent it was promoted from.
|
|
* Fix the "`Fragment Input Attachment Interface`" glossary entry to match
|
|
the specification body.
|
|
* Clarify the interaction of sRGB images used as storage or texel buffers
|
|
with <<textures-output-format-conversion, Texel Output Format
|
|
Conversion>>.
|
|
* Moved three valid usage statements from
|
|
slink:VkRenderPassMultiviewCreateInfo up to
|
|
slink:VkRenderPassCreateInfo, and added a new valid usage statement for
|
|
slink:VkRenderPassInputAttachmentAspectCreateInfo.
|
|
* Added valid usage statements for slink:VkBufferMemoryBarrier and
|
|
slink:VkImageMemoryBarrier reflecting the global requirement that
|
|
"`non-sparse resources must be bound to memory before being recorded to
|
|
command`".
|

|
|
|
Change log for April 5, 2018 Vulkan 1.1.72 spec update:
|
|
|
|
* Update release number to 72.
|
|
|
|
Github Issues:
|
|
|
|
* Restructure the repository to put the specification `Makefile` and
|
|
associated spec source material at the top level, `vk.xml` and
|
|
associated scripts material in `xml/`, and generated include and source
|
|
files in `include/vulkan/` and `src/ext_loader/`, respectively (public
|
|
issue 436).
|
|
* Add missing bullet point markup to flink:vkCmdCopyImage valid usage
|
|
statement, so it gets a VUID assigned (public issue 627).
|
|
* Fix broken links in a couple of extension appendices (public pull
|
|
request 665).
|
|
* Add the \<platform> tag to the index in section 4.1 of the registry
|
|
schema documentation, and add the protect= attribute of \<extension>
|
|
tags to the comments in `registry.rnc` (public issues 673, 678).
|
|
* Add missing valid usage statements for sparse image interactions to
|
|
flink:VkImageCreateInfo (public pull request 675).
|
|
* Fix improper usage and grammar of "`can: not`" (public pull request
|
|
681).
|
|
* Remove duplicate spec language and NOTE on present layout between the
|
|
flink:vkAcquireNextImageKHR and flink:vkAcquireNextImage2KHR commands
|
|
(public pull request 685).
|
|
* Fix some typos and markup issues (public pull request 689; public issues
|
|
642, 667, 687).
|
|
* Fix typo etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT ->
|
|
ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT in the
|
|
<<external-semaphore-handle-types-compatibility, External semaphore
|
|
handle types compatibility>> table (public pull request 691).
|
|
|
|
Internal Issues:
|
|
|
|
* Remove the need for the "`noautovalidity`" attribute on extension
|
|
structures in `vk.xml`. It is now implied by the "`structextends`"
|
|
attribute instead (internal issue 942).
|
|
* Replace uses of "`currently bound`" with "`bound`", since "`currently`"
|
|
is redundant and distracting, and add a corresponding rule to the style
|
|
guide (internal issue 993).
|
|
* Fixed subtle issues with the last updates to flink:vkAcquireNextImageKHR
|
|
language that had resulted in ambiguities (internal issue 1178).
|
|
* Make it clear that only one query of a given type is allowed at a time
|
|
by reordering valid usage statements for flink:vkCmdBeginQuery and
|
|
flink:vkCmdEndQuery, and removing redundant ones (internal issue 1213).
|
|
* Swapped OL1 and OL3 in `tessparamUL.svg` to match previous version, and
|
|
fixed where "`(no edge)`" appears (internal issue 1215).
|
|
|
|
Other Issues:
|
|
|
|
* Fixed a minor problem with the valid usage statement extraction script,
|
|
and corresponding markup in the spec source.
|
|
|
|
New Extensions:
|
|
|
|
* `VK_AMD_shader_core_properties`
|
|
* `VK_EXT_descriptor_indexing`
|
|
* `VK_NV_shader_subgroup_partitioned`

Change log for March 16, 2018 Vulkan 1.1.71 spec update:
|
|
|
|
* First public update for Vulkan 1.1.
|
|
|
|
Github Issues:
|
|
|
|
* Refer to standard sparse image block shape format tables explicitly in
|
|
the <<sparsememory-standard-shapes, Standard Sparse Image Block Shapes>>
|
|
section (public issue 93).
|
|
* Add the missing definition of the code:LocalInvocationIndex decoration
|
|
in the <<interfaces-builtin-variables, Built-In Variables>> section
|
|
(public issue 532).
|
|
* Clarify dynamic state definition in the introduction to the <<pipelines,
|
|
Pipelines>> section and the new <<pipelines-dynamic-state, Dynamic
|
|
State>> subsection (public issue 620).
|
|
* Clarified deprecation statement in the `VK_AMD_negative_viewport_height`
|
|
appendix (public issue 674).
|
|
* Fix parameter descriptions for flink:vkCreateIndirectCommandsLayoutNVX
|
|
(public issue 677).
|
|
|
|
Internal Issues:
|
|
|
|
* Remove description of <<primsrast-points, rasterization point size>>
|
|
being taken from the tessellation control shader, since there are no
|
|
circumstances under which you can have TCS without TES (internal issue
|
|
522).
|
|
* Define <<copies-images-format-size-compatibility, _size-compatible_
|
|
image formats>> for flink:vkCmdCopyImage, add it to the glossary, and
|
|
use that definition for slink:VkImageViewCreateInfo (internal issue
|
|
771).
|
|
* Change brief descriptions of enumerant names, and of parameters which
|
|
are enumerants, from "`enum *indicates*`" to "`enum *specifies*`" for
|
|
consistency, and add a markup style guide rule (internal issue 862).
|
|
* Clarify how execution dependencies interact with
|
|
<<synchronization-submission-order, submission order>> at numerous
|
|
places in the <<renderpass, Render Pass>> and <<synchronization,
|
|
Synchronization>> chapters (internal issue 1062).
|
|
* Clarify statement in the <<interfaces-resources-setandbinding,
|
|
DescriptorSet and Binding Assignment>> section that only interface
|
|
variables statically used by the entry point used in a pipeline must be
|
|
present in the descriptor set layout (internal issue 1172).
|
|
* Flip sparse image diagrams with partially full mip levels vertically, to
|
|
match graph origins of other image diagrams (internal issue 1176).
|
|
* Update new SVG diagrams to have consistent style and base font size,
|
|
increase consistency of primitive topology diagrams, and add a section
|
|
to the style guide on creating and editing images in a consistent style
|
|
(internal issue 1177).
|
|
* Resolve problems with valid usage statement extraction by fixing
|
|
existing VUID tags for interfaces promoted to version 1.1 and fixing
|
|
conditional directives around
|
|
VUID-VkMemoryDedicatedAllocateInfo-image-01797 (internal issue 1184).
|
|
* Strip `KHR` suffixes from a few interfaces promoted to Vulkan 1.1 that
|
|
were missed previously (internal issue 1185).
|
|
* Restrict code:OpImageQuerySizeLod and code:OpImageQueryLevels to only
|
|
work on code:Image operands with their code:Sampled operand set to 1. In
|
|
other words, these operations are not defined to work with storage
|
|
images (internal issue 1193).
|
|
* Recycle extension slot for extension #82 in `vk.xml`. This extension was
|
|
never published (internal issue 1195).
|
|
* Add an issue to the `VK_KHR_maintenance1` appendix noting that zero
|
|
height viewports are allowed when this extension is enabled (internal
|
|
issue 1202).
|
|
* Fix slink:VkDescriptorSetLayoutBinding description so that shader stages
|
|
always use descriptor bindings, not the other way around (internal issue
|
|
1206).
|
|
* Fix field name for
|
|
slink:VkInputAttachmentAspectReference::pname:inputAttachmentIndex
|
|
(internal issue 1210).
|
|
|
|
Other Issues:
|
|
|
|
* Fix a few broken links in the <<versions-1.1, Version 1.1>> appendix.
|
|
* Replace a few old refBegin/refEnd tags with open block markup around
|
|
interfaces, and remove old KHX VUID tags that were breaking the valid
|
|
usage statement extraction.
|
|
* Fix error codes accidentally tagged as success codes in `vk.xml` for
|
|
flink:vkGetSwapchainCounterEXT.
|
|
* Added valid usage statements for ftext:vkBind*Memory2 input structures
|
|
stext:VkBind*MemoryInfo, and fix a pname:image -> pname:buffer typo in a
|
|
couple of places.
|
|
* Fix swapped descriptions of elink:VkDescriptorType enums
|
|
ename:VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE and
|
|
ename:VK_DESCRIPTOR_TYPE_STORAGE_IMAGE (reported via tweet).
|
|
|

Change log for March 7, 2018 Vulkan 1.1.70 spec update:
|
|
|
|
* Vulkan 1.1 initial release. Bump API patch number and header version
|
|
number to 70 for this update. The patch number will be used for both
|
|
Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment
|
|
continuously from the previous Vulkan 1.0.69 update.
|
|
|
|
NOTE: We are not publishing an updated 1.0.70 specification, or 1.1
|
|
reference pages, along with 1.1.70. There are still minor issues to work
|
|
out with those build targets. However, we will soon generate all three
|
|
types of documents as part of the regular spec update cycle.
|
|
|
|
NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the
|
|
current specification in the `master` branch. The `1.0` branch is out of
|
|
date and will not be maintained, since we will be generating both 1.1
|
|
and 1.0 specifications from the `master` branch in the future.
|
|
|
|
Github Issues:
|
|
|
|
* Clarify how mapped memory ranges are flushed in
|
|
flink:vkFlushMappedMemoryRanges (public issue 127).
|
|
* Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a
|
|
list of tasks that each command performs, rather than necessarily being
|
|
discrete pieces of hardware that one task flows through. Add a
|
|
"`synchronization command`" pipeline type which all synchronization
|
|
command execute (it's just TOP + BOTTOM), with an explanatory note
|
|
(public issue 554).
|
|
|
|
Internal Issues:
|
|
|
|
* Regenerate all images used in the spec in Inkscape with a consistent
|
|
look-and-feel, and adjust image size attributes so they're all legible,
|
|
and not too large with respect to the spec body text (internal issue
|
|
701).
|
|
* Document in the <<extensions,extensions>> appendix and in the style
|
|
guide that `KHX` extensions are no longer supported or used in the
|
|
Vulkan 1.1 timeframe (internal issue 714).
|
|
* Remove the leftover equations_temp directory after PDF build completes
|
|
(internal issue 925).
|
|
* Update the <<credits, Credits (Informative)>> appendix to include
|
|
contributors to Vulkan 1.1, and to list them according to the API
|
|
version(s) they contributed to (internal issue 987).
|
|
* Add a NOTE to the introduction explaining that interfaces defined by
|
|
extensions which were promoted to Vulkan 1.1 are now expressed as
|
|
aliases of the Vulkan 1.1 type (internal issue 991).
|
|
* Instrument spec source conditionals so spec can be built with 1.1
|
|
features, extensions promoted to 1.1, or both (internal issues 992,
|
|
998).
|
|
* Modify the XML schema and tools to support explicit aliasing of types,
|
|
structures, and commands, and use this to express the promotion of 1.0
|
|
extensions to 1.1 core features, by making the extension interfaces
|
|
aliases of the core features they were promoted to. Mark up promoted
|
|
interfaces to allow still generating 1.0 + extension specifications
|
|
(internal issue 991).
|
|
* Platform names, along with corresponding preprocessor symbols to enable
|
|
extensions specific to those platforms, are now reserved in vk.xml using
|
|
the <platform> tag. Update the registry schema and schema specification
|
|
to match (internal issue 1011).
|
|
* Updated the <<textures-texel-replacement, Texel Replacement>> section to
|
|
clarify that reads from invalid texels for image resources result in
|
|
undefined values (internal issue 1014).
|
|
* Modify description of patch version so it continues to increment across
|
|
minor version changes (internal issue 1033).
|
|
* Clarify and unify language describing physical device-level core and
|
|
extension functionality in the <<fundamentals-validusage-extensions,
|
|
Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid
|
|
Usage for Newer Core Versions>>, <<initialization-functionpointers
|
|
Command Function Pointers>>, <<initialization-phys-dev-extensions,
|
|
Extending Physical Device From Device Extensions>>
|
|
<<extended-functionality-instance-extensions-and-devices, Instance
|
|
Extensions and Device Extensions>> sections and for
|
|
flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that
|
|
instance-level functionality is tied to the loader, and independent of
|
|
the ICD; physical device-level functionality is tied to the ICD, and
|
|
associated with device extensions; physical devices are treated more
|
|
uniformly between core and extensions; and instance and physical
|
|
versions can be different (internal issue 1048).
|
|
* Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>>
|
|
section to clarify the ability for pending command buffers to transition
|
|
to the invalid state after submission, and add a command buffer
|
|
lifecycle diagram (internal issue 1050).
|
|
* Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters
|
|
are ignored when push descriptors are not supported (internal issue
|
|
1054).
|
|
* Specify that flink:vkCreateImage will return an error if the image is
|
|
too large, in a NOTE in the slink:VkImageFormatProperties description
|
|
(internal issue 1078).
|
|
* Remove near-duplicate NOTEs about when to query function pointers
|
|
dynamically in the <<initialization, Initialization>> chapter and
|
|
replace by extending the NOTE in the <<fundamentals-abi, Application
|
|
Binary Interface>> section (internal issue 1085).
|
|
* Restore missing references to "`Sparse Resource Features`" in the
|
|
flink:VkBufferCreateFlagBits description (internal issue 1086).
|
|
* Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl`
|
|
specification, the <<descriptorsets, Resource Descriptors>> section and
|
|
its subsections, and the <<interfaces-resources-descset, Descriptor Set
|
|
Interface>> for consistency, reduction of duplicate information, and
|
|
removal of GLSL correspondance/examples (internal issue 1090).
|
|
* Correctly describe code:PrimitiveId as an Input for tessellation control
|
|
and evaluation shaders, not an Output (internal issue 1109).
|
|
* Relax the requirements on chroma offsets for nearest filtering in
|
|
<<textures-implict-reconstruction, Implicit Reconstruction>> (internal
|
|
issue 1116).
|
|
|
|
Other Issues:
|
|
|
|
* Clarify the intended relationship between specification language and
|
|
certain terms defined in the Khronos Intellectual Property Rights
|
|
policy. Specific changes include:
|
|
** Rewrote IP/Copyright preamble and introduction to better agree with
|
|
normative language both as laid out in the introduction, and the
|
|
Khronos IPR policy.
|
|
** Added notion of fully informative sections, which are now tagged with
|
|
"`(Informative)`" in their titles.
|
|
** Removed non-normative uses of the phrase "`not required`"
|
|
** Clarified the distinction between terms "`optional`" and "`not
|
|
required:`" as they relate to the IPR Policy, and updated specification
|
|
text to use terms consistent with the intent.
|
|
** Reduced additions to RFC 2119, and ensured the specification agreed
|
|
with the leaner language.
|
|
** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from
|
|
normative text.
|
|
** Moved several paragraphs that should not have been normative to
|
|
informative notes.
|
|
** Clarified a number of definitions in the Glossary.
|
|
** Updated the document writing guide to match new terminology changes.
|
|
* Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire,
|
|
application memory lifetime>> language that for objects other than
|
|
descriptor sets, a slink:VkDescriptorSetLayout object used in the
|
|
creation of another object (such as slink:VkPipelineLayout or
|
|
slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation
|
|
of that object and can be safely destroyed afterwards.
|
|
* Updated the <<textures-scale-factor, Scale Factor Operation>> section to
|
|
use the ratio of anisotropy, rather than the integer sample rate, to
|
|
perform the LOD calculation. The spec still allows use of the sample
|
|
rate as the value used to calculate the LOD, but no longer requires it.
|
|
* Update `vulkan_ext.c` to include all platform-related definitions from
|
|
the Vulkan platform headers, following the split of the headers into
|
|
platform-specific and non-platform-specific files.
|
|
* Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter
|
|
which accidentally duplicated an anchor in the pipelines chapter. There
|
|
were no reference to this anchor, fortunately.
|
|
* Add valid usage statement for slink:VkWriteDescriptorSet and
|
|
slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout
|
|
used to allocate the source and destination sets must not have been
|
|
destroyed at the time flink:vkUpdateDescriptorSets is called.
|
|
* Document mapping of subgroup barrier functions to SPIR-V, and clarify a
|
|
place where subgroupBarrier sounds like it's execution-only in the
|
|
standalone `GL_KHR_shader_subgroup` specification.
|
|
* Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with
|
|
the default Arial font family replaced by the sans-serif Noto font
|
|
family.
|
|
* Numerous minor updates to README.adoc, build scripts, Makefiles, and
|
|
registry and style guide specifications to support Vulkan 1.1 outputs,
|
|
use them as defaults, and remove mention of `KHX` extensions, which are
|
|
no longer supported.
|
|
|
|
|
|
New Extensions:
|
|
|
|
* `VK_EXT_vertex_attrib_divisor`

Change log for February 19, 2018 Vulkan 1.0.69 spec update:
|
|
|
|
* Bump API patch number and header version number to 69 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Clean up description of synchronization for flink:vkAcquireNextImageKHR
|
|
(public issue 626).
|
|
* Move valid usage statements requiring offset and extent to respect image
|
|
transfer granularity requirements of the queue family they are submitted
|
|
against from slink:VkImageCopy and slink:VkBufferImageCopy to the
|
|
corresponding flink:vkCmdCopyImage, flink:vkCmdCopyBufferToImage, and
|
|
flink:vkCmdCopyImageToBuffer commands, where are relevant information is
|
|
known (public issue 654).
|
|
* Clarify that flink:vkGetDeviceProcAddr only supports device-level
|
|
commands (public issue 655).
|
|
|
|
Internal Issues:
|
|
|
|
* Associate each elink:VkDescriptorType with a type of descriptor, and
|
|
link to descriptions of those types (internal issue 860).
|
|
* Rework valid usage extraction script to better utilize and respond to
|
|
spec markup, and fix some spec markup accordingly (internal issues 846,
|
|
909, 945).
|
|
* Rephrase flink:vkCmdPushConstants valid usage to allow overlapping push
|
|
constant ranges in different shader stages (internal issue 1103).
|
|
* Fix problem with diff_html target in extension.rb (internal issue 1104).
|
|
* Modify valid usage statements for slink:VkClearDepthStencilValue,
|
|
slink:VkGraphicsPipelineCreateInfo, slink:VkViewport, and
|
|
flink:vkCmdSetDepthBounds, and the description of vkCmdSetDepthBias, to
|
|
clarify that clamping is applied if and only if the
|
|
`VK_EXT_depth_range_unrestricted` is not enabled (internal issue 1124),
|
|
in versions of the specification built with that extension included.
|
|
* Resolve contradictions and use of undefined "`per-sample shading`" term
|
|
in the <<primsrast-sampleshading, Sample Shading>> and
|
|
<<shaders-fragment-execution, Fragment Shader Execution>> sections; for
|
|
the <<features-features-sampleRateShading, sampleRateShading feature>>;
|
|
for code:FragCoord, code:SampleId, and code:SamplePosition; and for
|
|
slink:sname:VkPipelineMultisampleStateCreateInfo (internal issue 1134).
|
|
* Clarify the meaning of the ptext:maxDescriptorSet* limits in footnote 8
|
|
of the <<features-limits-required,Required Limits>> table (internal
|
|
issue 1139).
|
|
* Fix broken NOTE markup in slink:VkSamplerCreateInfo.txt (internal issue
|
|
1140).
|
|
* Remove extend comparison language from valid usage statement for
|
|
slink:VkImageCreateInfo, turning it into a simple validation of
|
|
pname:mipLevels against pname:maxMipLevels (internal issue 1151).
|
|
* Update valid usage statements for slink:VkImageCopy when the
|
|
`VK_KHR_maintenance1` extension is enabled to allow multi-slice 2D <->
|
|
3D copies when the pnaem:extent.depth parameter specifies the number of
|
|
layers being copied, and matches the
|
|
slink:VkImageSubresourceLayers.layerCount of the 2D image (internal
|
|
issue 1152).
|
|
* Rephrase memory / control barrier rules in the
|
|
<<spirvenv-module-validation, Validation Rules within a Module>> section
|
|
to avoid "`not use none`", which could be misconstrued to allow no
|
|
synchronization semantics, and only storage class semantics (internal
|
|
issue 1154).
|
|
|
|
Other Issues:
|
|
|
|
* Move GLSL extension specifications to the KhronosGroup/GLSL repository
|
|
on Github.
|
|
* Add missing description of ename:VK_FILTER_CUBIC_IMG enum to
|
|
slink:VkFilter.
|
|
* Update description of code:PrimitiveId in the
|
|
<<interfaces-builtin-variables,Built-In Variables>> section to clarify
|
|
its behavior.
|
|
* Disallow disjoint images from being used with dedicated-memory images in
|
|
slink:VkMemoryDedicatedAllocateInfoKHR.
|
|
* Update README to suggest older versions of "mathematical" and
|
|
"ruby-gems" packages for use on Cygwin.
|
|
* Fix typos
|
|
|
|
New Extensions:
|
|
|
|
* `VK_AMD_buffer_marker`

|
|
Change log for January 15, 2018 Vulkan 1.0.68 spec update:
|
|
|
|
* Bump API patch number and header version number to 68 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Added more details in the
|
|
<<extended-functionality-extensions-compatibility, Extension
|
|
Compatibility>> section, allowing explicit incompatibilities, and
|
|
simplify corresponding language in the style guide, which now defers to
|
|
the API Specification on this point (public issue 638).
|
|
* Fix typo in description of slink:VkCommandBufferLevel::pname:level
|
|
(public issue 651).
|
|
* Only include extension-dependent valid usage statement for
|
|
slink:VkImageSubresourceRange, and note that the extension names for
|
|
header files described in the <<boilerplate-wsi-header, Window
|
|
System-Specific Header Control>> section are only valid links, when the
|
|
specification being viewed is built with the corresponding extensions
|
|
enabled (public issue 652).
|
|
|
|
Internal Issues:
|
|
|
|
* Add language to elink:VkResult specifying that when commands return an
|
|
error, output parameter contents are undefined instead of unmodified
|
|
(except for pname:sType and pname:pNext). Note that this is a behavior
|
|
change. Add notes calling out slink:VkImageFormatProperties as an
|
|
exception (internal issue 1118).
|
|
* Add "`general-purpose`" to the style guide, and correct existing uses of
|
|
"`general purpose`" as an adjective (internal issue 1121).
|
|
* Add the ename:VK_DEBUG_REPORT_OBJECT_TYPE_VALIDATION_CACHE_EXT_EXT token
|
|
for the `VK_EXT_validation_cache` extension, following the same naming
|
|
pattern as other tokens in the extension, but keep the old
|
|
ename:VK_DEBUG_REPORT_OBJECT_TYPE_VALIDATION_CACHE_EXT token around for
|
|
backwards compatibility (internal issue 1126).
|
|
|
|
Other Issues:
|
|
|
|
* Specify that flink:vkCmdSetDiscardRectangleEXT does not affect copies or
|
|
clears, matching existing language for the scissor rectangle test.
|
|
* Move the <<boilerplate-sType, pname:sType>> definition from the
|
|
boilerplate appendix to the Fundamentals chapter, putting it together
|
|
with the valid usage of pname:sType rather than having the definition
|
|
split across two places.
|
|
* Inline all of the etext:Vk*Flags definitions, moving each one from the
|
|
boilerplate appendix to appear either after the corresponding
|
|
etext:Vk*FlagBits value if one is defined, or after the first structure
|
|
that includes them if not.
|

Change log for January 5, 2018 Vulkan 1.0.67 spec update:
|
|
|
|
* Bump API patch number and header version number to 67 for this update.
|
|
* Update copyright dates to 2018
|
|
|
|
Github Issues:
|
|
|
|
* Fix texture lookup functions in `GL_KHR_vulkan_glsl` specification
|
|
(public pull request 363).
|
|
* Clarify the state waited semaphores are left in when a call to
|
|
flink:vkQueuePresentKHR fails (public issue 572).
|
|
* Cleanup descriptions of slink:VkObjectTablePushConstantEntryNVX and
|
|
slink:VkObjectTableDescriptorSetEntryNVX (public issue 583)
|
|
* Remove redundant flink:vkCmdSetDiscardRectangleEXT valid usage
|
|
statements (public pull 586).
|
|
* Make dynamic state array length valid usage statements implicit for
|
|
flink:vkCmdSetViewportWScalingNV, flink:vkCmdSetDiscardRectangleEXT, and
|
|
flink:vkCmdSetViewport (public pull 589).
|
|
* Clarify meaning of window extent (0,0) in slink:VkSwapchainKHR for the
|
|
Windows and X11 platforms, in their respective extensions (public issue
|
|
590).
|
|
* Allow flink:vkGetPastPresentationTimingGOOGLE to return
|
|
ename:VK_INCOMPLETE (public issue 604).
|
|
* Add synchronization valid usage statements to flink:vkAcquireNextImage
|
|
(public pull 611).
|
|
* Fix some broken external links and internal xrefs (public pull 613).
|
|
* Clean up slink:VkViewport valid usage statements in the presence or
|
|
absence of relevant extensions (public pull 623).
|
|
* Remove
|
|
ename:VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_STENCIL_ATTACHMENT_OPTIMAL_KHR
|
|
token from VK_KHR_maintenance2 from the non-extension VU path for
|
|
slink:VkGraphicsPipelineCreateInfo (public issue 628).
|
|
* Miscellaneous minor markup fixes - extension name strings (public pull
|
|
631), Notes (pull 633), queue names emitted by generator scripts (pull
|
|
634), block formatting in slink:VkDescriptorUpdateTemplateEntryKHR (pull
|
|
635), ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_CUBIC_BIT_IMG (pull
|
|
641), quotes and apostrophes (pull 643),
|
|
* Miscellaneous minor grammar fixes (public pull 644).
|
|
* Fix markup macros so usage like ptext:*Src* works (public pull 647).
|
|
|
|
Internal Issues:
|
|
|
|
* Clarify in the `VK_KHR_surface` and `VK_KHR_swapchain` extensions that
|
|
parameter combinations which aren't supported for normal images are also
|
|
unsupported for presentable images, even if the parameter values are
|
|
individually supported as reported by the surface capability queries
|
|
(internal issue 1029).
|
|
* Fixed XML typo in the valid value field of the pname:sType member of
|
|
slink:VkPhysicalDeviceExternalMemoryHostPropertiesEXT (internal issue
|
|
1100).
|
|
|
|
Other Issues:
|
|
|
|
* Add memory semantics validity rules to the <<spirvenv-module-validation,
|
|
Validation Rules within a Module>> section of the SPIR-V environment
|
|
appendix, and specify that sequentiality consistency is not supported.
|
|
This forbids certain cases like "`Load+Release`" that we don't expect to
|
|
ever be meaningful.
|
|
* Document mapping of OpenGL Shading Language barriers to SPIR-V scope and
|
|
semantics in the `GL_KHR_vulkan_glsl` specification.
|
|
|
|
New Extensions:
|
|
|
|
* `VK_EXT_conservative_rasterization`
|

|
Change log for November 27, 2017 Vulkan 1.0.66 spec update:
|
|
|
|
* Bump API patch number and header version number to 66 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Clarified how and when ename:VK_ERROR_TOO_MANY_OBJECTS is generated in
|
|
flink:vkAllocate Memory, and remove incorrect valid usage statement
|
|
about exceeding the API limit (public issue 356).
|
|
* Minor clarification of the description of
|
|
flink:vkUpdateDescriptorSetWithTemplateKHR::pname:descriptorUpdateTemplate
|
|
(public issue 564).
|
|
* Minor fixes for flink:vkCmdSetViewportWScalingNV (public pull request
|
|
588).
|
|
* Fix random name markup issues (public pull request 603).
|
|
* Fix code:BuiltIn decoration typo in the <<fxvertex-attrib, Vertex
|
|
Attributes>> section (public pull request 606).
|
|
* Fix synchronization language following the definition of
|
|
flink:vkAcquireNextImageKHR (public issue 607).
|
|
* Restore descriptions of several commands and structures missing from the
|
|
generated spec due to a mistyped asciidoctor conditional (public issue
|
|
612).
|
|
* Fix 1.0.41 changelog to refer to public issues 403/404 (public issue
|
|
618).
|
|
|
|
Internal Issues:
|
|
|
|
* Refactor valid usage statements with internal conditionals in
|
|
`copies.txt`, `pipelines.txt`, `renderpass.txt`, and `resources.txt` so
|
|
each branch of the conditional appears as a standalone statement which
|
|
can contain a separate VUID. This should have no impact on the generated
|
|
specs, but is necessary given the present state of the VU extractor and
|
|
the validation layer code that consumes them (internal issue 1043).
|
|
* Fix VkQueueGlobalPriorityEXT enum values missing _EXT suffix (internal
|
|
issue 1045).
|
|
* Clarified initial ownership of resources bound to shared memory objects,
|
|
(internal issue 1068).
|
|
* Fix duplicated valid usage ID tag for flink:vkCmdCopyImage, and make the
|
|
required layouts include ename:VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL in
|
|
both cases (internal issue 1084).
|
|
|
|
Other Issues:
|
|
|
|
* Remove the noise functions from GLSL for SPIR-V for Vulkan in the
|
|
`GL_KHR_vulkan_glsl.txt` extension.
|
|
|
|
New Extensions:
|
|
|
|
* `VK_EXT_external_memory_host`
|
|
* `VK_EXT_external_memory_dma_buf`
|
|
* `VK_EXT_queue_family_foreign`

Change log for October 27, 2017 Vulkan 1.0.65 spec update:
|
|
|
|
* Bump API patch number and header version number to 65 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Replaced inaccurate "`pixel`" with "`texel`" or "`compressed texel
|
|
block`" as appropriate in the <<sparsememory, Sparse Resources>> chapter
|
|
(public issue 86).
|
|
* Attempt to clarify security/integrity guarantees in the
|
|
<<fundamentals-errors, Errors>> section (public issue 147).
|
|
* Update the <<memory-device,Device Memory>> section with clarifications
|
|
and markup fixes (public pull request 194).
|
|
* Fix typo VkDeviceCreateInfo -> slink:VkDebugMarkerObjectNameInfoEXT in
|
|
sample code for `VK_EXT_debug_marker` extension (public pull request
|
|
227).
|
|
* Clarified slink:VkFramebufferCreateInfo language regarding concurrent
|
|
use of attachment resources during a render pass instance (public issue
|
|
299).
|
|
* Added overlap rules for destination regions in <<copies,copy commands>>.
|
|
Also unified the sparse and non-sparse source-destination overlap rules,
|
|
since the non-sparse rules were technically inaccurate in the face of
|
|
aliasing in flink:vkBindMemory2 - the new rules are true regardless
|
|
(public issue 317).
|
|
* Clarified the <<features-features-samplerAnisotropy,
|
|
pname:samplerAnisotropy feature>> to only affect the
|
|
slink:VkSamplerCreateInfo::pname:anisotropyEnable value, and that
|
|
pname:maxAnisotropy is ignored when pname:anisotropyEnable is VK_FALSE
|
|
(public issue 503).
|
|
* Clarify pointer valid usage statements to use "`valid pointer to valid
|
|
_object_`" terminology and update the
|
|
<<fundamentals-validusage-pointers,Valid Usage for Pointers>> section
|
|
accordingly (public pull request 547).
|
|
* Some operations that use integer coordinates can also accept a LOD to
|
|
sample from. Add a description of that selection and the validity
|
|
conditions in the new <<textures-integer-coordinate-operations, Integer
|
|
Texel Coordinate Operations>> section (public issue 548).
|
|
* Update stext:VkImageSubresource* valid usage statements (public pull
|
|
request 550).
|
|
* Added text tying ename:VK_OUT_OF_POOL_MEMORY error for
|
|
flink:vkAllocateDescriptorSets to the number of descriptor types in the
|
|
allocating pool. Removed redundant "`length`" text about number of
|
|
descriptors returned (public issue 582).
|
|
* Update slink:VkSwapchainCreateInfoKHR descriptions (public pull request
|
|
585).
|
|
* Update slink:VkPipelineViewportWScalingStateCreateInfoNV and related
|
|
structures' valid usage statements (public pull request 587).
|
|
* Change some dates to conform to ISO 8601 as specified in the style guide
|
|
(public pull request 601).
|
|
* Fix some math markup problems and be more consistent in use of asciidoc
|
|
math markup (public pull request 602).
|
|
|
|
Internal Issues:
|
|
|
|
* Clarified that attribute reads from incomplete vertex buffer elements
|
|
are considered out of bounds accesses, in the
|
|
slink:VkPhysicalDeviceFeatures and flink:vkCmdBindVertexBuffers.txt
|
|
sections (internal issue 842).

Change log for October 20, 2017 Vulkan 1.0.64 spec update:
|
|
|
|
* Bump API patch number and header version number to 64 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Add chapter name to the PDF page footer (public pull request 458).
|
|
* Fix several mistaken references to the nonexistent etext:VK_DEVICE_LOST
|
|
status to etext:VK_ERROR_DEVICE_LOST (public pull request 502).
|
|
* Fix description of the tlink:PFN_vkDebugReportCallbackEXT debug report
|
|
callback function pointer to match the validation layer behavior (public
|
|
issue 534).
|
|
* Document experimental KHX extensions and alternate vendor author IDs
|
|
also ending in X in more detail in the <<extensions, Layers &
|
|
Extensions>> appendix, the extensions section of the style guide, and
|
|
the registry schema description document (public issues 536, 580).
|
|
* Fix references to ptext:pDepthStencil to properly refer to
|
|
pname:pDepthStencilState or pname:pRasterizationState as appropriate in
|
|
the slink:VkGraphicsPipelineCreateInfo description (public issue 542).
|
|
* Fix wrong parameter name in slink:VkPipelineMultisampleStateCreateInfo
|
|
valid usage (public pull request 571).
|
|
|
|
Internal Issues:
|
|
|
|
* Update the style guide to describe how to write LaTeX math expressions
|
|
in table cells (internal issue 908).
|
|
* Define how framebuffer-local dependencies work between subpasses with
|
|
the same or different numbers of samples, in the
|
|
slink:VkSubpassDescription and <<synchronization-framebuffer-regions,
|
|
Framebuffer Region Dependencies>> sections. This clarifies which samples
|
|
in an input attachment you are allowed to access after a
|
|
framebuffer-local dependency (internal issue 915).
|
|
* Specify which storage classes can have an initializer in the
|
|
<<spirvenv-module-validation, Validation Rules within a Module>> section
|
|
(internal issue 1023).
|
|
* Use "LOD" consistently for "level-of-detail", to eliminate spelling
|
|
inconsistencies. The term is already standardized in the Glossary
|
|
(internal issue 1027).
|
|
|
|
Other Issues:
|
|
|
|
* Fix false positives in Makefile dependencies when rules fail, by
|
|
deleting partially-made targets.
|
|
|
|
New Extensions:
|
|
|
|
* `VK_AMD_shader_info`

Change log for October 13, 2017 Vulkan 1.0.63 spec update:
|
|
|
|
* Bump API patch number and header version number to 63 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Add missing valid usage statements for ptext:maxDescriptorSets*,
|
|
ptext:maxPerStageDescriptorInputAttachments, and
|
|
ptext:maxPerStageResources to slink:VkPipelineLayoutCreateInfo.txt,
|
|
flink:VkComputePipelineCreateInfo, and
|
|
flink:VkGraphicsPipelineCreateInfo (public issue 546).
|
|
* Fix typos in ftext:vkCmdDraw*AMD descriptions (public pull request 549).
|
|
* Fixed flink:vkCmdWriteTimestamp so it is not unnecessarily restricted to
|
|
queues supporting graphics or compute operations (public issue 558).
|
|
* Improvements to valid usage generator for output `*Flags` pointer
|
|
parameters and for some `void *` parameters (public pull requests 560,
|
|
562).
|
|
* Document `altlen` attribute in XML schema as valid C99 syntax and tweak
|
|
`vk.xml` to match (public pull request 566).
|
|
* Clarify when pname:fence is signaled by flink:vkQueueSubmit in a more
|
|
obvious place (public issue 577).
|
|
|
|
Internal Issues:
|
|
|
|
* Specify a whitelist of supported SPIR-V Storage Classes in the
|
|
<<spirvenv-module-validation, Validation Rules within a Module>>
|
|
appendix (internal SPIR-V issue 166).
|
|
* Relax the shared semaphore wait timeout requirement in the
|
|
<<synchronization-semaphores-importing, Importing Semaphore Payloads>>
|
|
section (internal issue 820).
|
|
* Update the <<textures-image-level-selection, Image Level(s) Selection>>
|
|
equations so that the parameters returned by the level-of-detail query
|
|
appear explicitly, also fixing the issue that linear filtering would
|
|
select a level below the base level for magnification (internal issue
|
|
926).
|
|
* Disallow creation of a swapchain with zero pname:imageExtent in
|
|
slink:VkSurfaceCapabilitiesKHR and slink:VkSwapchainCreateInfoKHR
|
|
(internal issue 1020).
|
|
|
|
Other Issues:
|
|
|
|
* Clarify in <<textures-operation-validation,Image View Validation>> that
|
|
the layout of subresources in an image view must have a layout that
|
|
matches that written into the descriptor, and that this section is about
|
|
validating image views, not images.
|
|
|
|
New Extensions:
|
|
|
|
* `VK_EXT_global_priority`
|
|

|
|
Change log for October 6, 2017 Vulkan 1.0.62 spec update:
|
|
|
|
* Bump API patch number and header version number to 62 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Move asciidoc conditionals for `VK_KHR_maintenance1` in
|
|
slink:VkDescriptorSetAllocateInfo so valid usage statements for
|
|
`VK_KHR_push_descriptor` aren't accidentally removed when the first
|
|
extension isn't enabled (public issue 573).
|
|
|
|
Internal Issues:
|
|
|
|
* Specify constraints on concurrent access to fences that share payload in
|
|
the <<synchronization-fences-importing, Importing Fence Payloads>> and
|
|
<<synchronization-semaphores-waiting-state, Semaphore State Requirements
|
|
For Wait Operations>> sections (internal issue 820).
|
|
* Define the term "`retired swapchain`", reorganize some swapchain
|
|
language, and improve language for pname:oldSwapchain in
|
|
flink:VkSwapchainCreateInfoKHR, the <<swapchain-wsi-image-create-info>>
|
|
table, flink:vkDestroySwapchainKHR, and flink:vkAcquireNextImage2KHX
|
|
(internal issue 869).
|
|
* Describe in the <<writing-arrays, Describing Properties of Array
|
|
Elements>> section of the style guide how and when to use "`each`" and
|
|
"`any`" to refer to properties of array elements, and make those uses in
|
|
the specification consistent (internal issue 884).
|
|
* Clarified that events cannot be used for cross-queue synchronization in
|
|
the <<synchronization-events, Events>> section and for
|
|
flink:vkCmdWaitEvents (internal issue 970).
|
|
* Add success and error codes to +vk.xml+ for
|
|
flink:vkCreateValidationCacheEXT (internal issue 995).
|
|
* Clarify aspect mask usage for image memory barriers of multi-plane
|
|
images in slink:VkImageSubresourceRange, slink:VkImageMemoryBarrier, and
|
|
the <<textures-layout-validation, Layout Validation>> section (internal
|
|
issue 996).
|
|
|
|
Other Issues:
|
|
|
|
* Fixed typo in flink:VkRenderPassSampleLocationsBeginInfoEXT (renamed
|
|
field pname:pSubpassSampleLocations to
|
|
pname:pPostSubpassSampleLocations).
|
|
* Add missing buffer usage requirements for indirect draws in
|
|
flink:vkCmdDrawIndirect, flink:vkCmdDrawIndirectCountAMD,
|
|
flink:vkCmdDrawIndexedIndirect, and
|
|
flink:vkCmdDrawIndexedIndirectCountAMD.
|
|
* Modify Makefile to allow specification to build in git "`detached HEAD`"
|
|
state.
|
|
* Update valid usage ID generation script to allow recursively operating
|
|
on all `.txt` files in a specified directory, and move the `startVUID`
|
|
tracking information into a separate python file that is automatically
|
|
updated by the script.
|
|
* Fixed errors in API example code for
|
|
flink:vkUpdateDescriptorSetWithTemplateKHR and
|
|
flink:vkCmdPushDescriptorSetWithTemplateKHR.
|
|
|
|
New Extensions:
|
|
|
|
* Add +vk.xml+ entries for pending `VK_ANDROID_native_buffer` extension
|
|
(note, this extension is not yet enabled).

Change log for September 15, 2017 Vulkan 1.0.61 spec update:
|
|
|
|
* Bump API patch number and header version number to 61 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Provide alternate length attributes (altlen=) in the XML schema, for
|
|
those using length attributes to generate code instead of documentation
|
|
(public issue 555).
|
|
* Fix erroneous references to `latex:` being used for asciidoc math
|
|
markup, rather than `latexmath:` (public pull request 556).
|
|
* Add author ID to XML for Kazan software renderer (public pull request
|
|
557).
|
|
|
|
Internal Issues:
|
|
|
|
* Add the <<fundamentals-abi,Application Binary Interface>> section
|
|
describing platform ABI requirements and recommendations, add examples
|
|
of function and function pointer declarations to the
|
|
<<boilerplate-platform-specific-calling-conventions, Platform-Specific
|
|
Calling Conventions>> section, and remove related language that existed
|
|
elsewhere in the specification (internal issue 64).
|
|
* Describe where to document valid usage interactions of chained
|
|
structures in the style guide, and fix one case now appearing in
|
|
slink:VkBufferCreateInfo instead of the child
|
|
slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue
|
|
715).
|
|
* Add example to the style guide of describing enumerated types which are
|
|
empty when the spec is built without relevant extensions enabled, and
|
|
apply it to existing examples for
|
|
elink:VkDescriptorSetLayoutCreateFlagBits and
|
|
elink:VkSubpassDescriptionFlagBits (internal issue 864).
|
|
* Add a note to the <<fundamentals-validusage-enums, Valid Usage for
|
|
Enumerated Types>> section that the special values suffixed with
|
|
etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and
|
|
etext:_MAX_ENUM are not part of the API and should: not be used by
|
|
applications (internal issue 872).
|
|
* Added note to flink:vkCmdUpdateBuffers explaining the performance
|
|
penalty for copies done in this way, and why the upper copy limit is
|
|
what it is (internal issue 952).
|
|
* Update `VK_KHX_device_group` to split some functionality into the new
|
|
`VK_KHR_bind_memory2` extension, and rename that functionality (internal
|
|
issue 969).
|
|
* Remove *Status* fields from extension appendices, since they are by
|
|
definition published and complete by the time they reach the public
|
|
github repository (internal issue 973).
|
|
|
|
Other Issues:
|
|
|
|
* Update Data Format specification dependency to version 1.2 and change
|
|
references to DF sections accordingly.
|
|
* Update XML to make the pname:pAllocator parameter of
|
|
flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in
|
|
the `VK_EXT_display_control` extension as optional.
|
|
|
|
New Extensions:

Change log for September 5, 2017 Vulkan 1.0.60 spec update:
|
|
|
|
* Bump API patch number and header version number to 60 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Document that <<queries-timestamps, Timestamp Queries>> can only be
|
|
meaningfully compared when they are written from the same queue (public
|
|
issue 216).
|
|
* Document that the `<extension>` tag `type` attribute is required for
|
|
non-disabled extensions (derived from, but does not close public issue
|
|
354).
|
|
* Clean up registry schema length attribute descriptions to be consistent
|
|
and correct (public issue 555).
|
|
|
|
Internal Issues:
|
|
|
|
* Replace as much of the hand-written extension appendix metadata as
|
|
possible with asciidoc includes generated from corresponding attributes
|
|
of +vk.xml+, and enhance the style guide to match. This avoids
|
|
inconsistencies between +vk.xml+ and the appendices, and produces a more
|
|
uniform style (internal issue 137).
|
|
* Remove the generated extDependency.{py,sh} files from the tree and
|
|
create them dynamically on demand instead, reducing merge conflicts
|
|
(internal issue 713).
|
|
* Add a prototype tool for generating in-place difference markup for
|
|
sections guarded by asciidoc conditionals, and new syntax for open
|
|
blocks to support it (internal issue 833).
|
|
* Remove unnecessary restriction of etext:*SYNC_FD_BIT_KHR external handle
|
|
types to the same physical device in the
|
|
slink:VkPhysicalDeviceIDPropertiesKHR,
|
|
flink:VkImportMemoryWin32HandleInfoKHR,

slink:VkImportSemaphoreFdInfoKHR
|
|
<<external-memory-handle-types-compatibility, External memory handle

types compatibility>>, <<external-semaphore-handle-types-compatibility,
|
|
External semaphore handle types compatibility>>, and
|
|
<<external-fence-handle-types-compatibility, External fence handle types
|
|
compatibility>> sections (internal issue 956).
|
|
|
|
Other Issues:
|
|
|
|
* Remove dependency of +VK_KHX_device_group+ on +VK_KHR_swapchain+ (there
|
|
is an interaction, but not a strict dependency), and add a new
|
|
`extension` attribute to the `<require` XML tag to allow classifying a
|
|
subset of interfaces of an extension as requiring another extension.
|
|
Update the registry schema and documentation accordingly.
|
|
|
|
New Extensions:
|
|
|
|
* `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask`
|
|
GLSL extension)
|

|
|
* `VK_EXT_validation_cache`

Change log for August 19, 2017 Vulkan 1.0.59 spec update:
|
|
|
|
* Bump API patch number and header version number to 59 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Fix a few missing Implicit Valid Usage statements to indicate that a
|
|
common parent of two objects is required (public issue 497).
|
|
* Clarify render pass synchronization language for
|
|
slink:VkSubpassDependency and \<\<renderpass,render passes>> (public
|
|
issue 531).
|
|
* Rename ename:VK_STRUCTURE_TYPE_SURFACE_CAPABILITIES2_EXT to
|
|
ename:VK_STRUCTURE_TYPE_SURFACE_CAPABILITIES_2_EXT for consistency, and
|
|
add an alias for backwards compatibility (public issue 539).
|
|
|
|
Internal Issues:
|
|
|
|
* Add an explanation to the \<\<interfaces-builtin-variables-layer,
|
|
code:Layer>> description explaining that writing to invalid layers
|
|
results may or may not result in primitives being processed and fragment
|
|
shaders being run, and gives undefined results in the framebuffer
|
|
(internal issue 614)
|
|
* Add valid usage statement for slink:VkDescriptorSetLayoutBinding
|
|
requiring that input attachment descriptor bindings must not use
|
|
non-fragment stages (internal issue 933).
|
|
|
|
Other Issues:
|
|
|
|
* Makes description of pname:loadOp and pname:storeOp easier to read in
|
|
the \<\<renderpass-load-store-ops>> section.

|
|
|
|
* Bump API patch number and header version number to 58 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Update the <<interfaces-resources-descset,Descriptor Set Interface>>
|
|
section to allow multiple variables with the same descriptor set/binding
|
|
decorations, and require that all variables that are statically used
|
|
must be consistent with the pipeline layout. Allow
|
|
ename:VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER to be used with texture
|
|
and sampler variables (public issues 522, 524).
|
|
|
|
Internal Issues:
|
|
|
|
* Replace networkx package used for extension dependency generation with a
|
|
homegrown network dependency traverser (internal issue 713).
|
|
* Specify in the <<interfaces-fragmentoutput, Fragment Output Interface>>
|
|
section that if a fragment shader writes integers that cannot be
|
|
represented in the format of the colour attachment, then the result is
|
|
undefined (internal issue 893).
|
|
* Separate malformed valid usage statement for
|
|
slink:VkPipelineRasterizationStateCreateInfo into two (internal issue
|
|
918).
|
|
* Fix cases where the term 'pNext chain' is incorrectly used in reference
|
|
to functions, rather than their parameters. Replace 'pNext list' with
|
|
'pNext chain'. Fixed typo in the example code of
|
|
+VK_KHR_dedicated_allocation+ (internal issue 944).
|
|
* Fix typo in elink:VkExternalSemaphoreHandleTypeFlagBitsKHR enum
|
|
descriptions, replacing
|
|
etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT_KHR with
|
|
ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT_KHR, and make the
|
|
description more consistent with
|
|
VK_EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT_KHR (internal issue 950).
|
|
|
|
Other Issues:
|
|
|
|
* Clarify how pipeline stage masks affect
|
|
<<synchronization-pipeline-stages-masks, access and synchronization
|
|
scopes>>.
|
|
* Clarify that dedicated allocations do not allow aliasing in the
|
|
flink:vkBindBufferMemory and flink:vkBindImageMemory valid usage
|
|
statements.
|
|
* Correct specification of pname:dynamicCount for push_constant token in
|
|
slink:VkIndirectCommandsLayoutNVX.

|
|
block size (public issue 342).
|
|
* Update documentation of ename:VK_PIPELINE_CREATE_ALLOW_DERIVATIVES_BIT
|
|
to explicitly mention both graphics and compute pipelines (public issue
|
|
525).
|
|
|
|
Internal Issues:
|
|
|
|
* Document that
|
|
slink:VkPhysicalDeviceLimits::pname:framebufferColorSampleCounts does
|
|
not cover integer formats (internal issue 550).
|
|
* Add a note under slink:VkImageViewCreateInfo describing how values meant
|
|
for one format can be sanitized when used via another format (internal
|
|
issue 927).
|
|
* Add valid usage statements to ftext:vkCmd* documenting that image
|
|
subresources used as attachments must not be accessed as non-attachments
|
|
in a render pass (internal issue 929).
|
|
* Remove obsolete 'validextensionstructs' attribute from +vk.xml+, the XML
|
|
schema, and the schema documentation (internal issue 946).
|
|
|
|
New Extensions:

Change log for July 21, 2017 Vulkan 1.0.56 spec update:
|
|
|
|
* Bump API patch number and header version number to 56 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Add valid usage statements for commands introduced by
|
|
`VK_EXT_debug_report` and `VK_EXT_debug_marker` extensions, regarding
|
|
the valid pname:object and pname:objectType values (public issue 495).
|
|
* Modify `GL_KHR_vulkan_glsl` specification to document that uniform and
|
|
buffer block arrays each take only a single binding (public issue 514).
|
|
* Add `KHX` author tag to +vk.xml+ (public issue 526).
|
|
|
|
Internal Issues:
|
|
|
|
* Document use of code: macro for non-Vulkan APIs in the style guide
|
|
(internal issue 863).
|
|
* Document that reference page open block delimiters must not contain
|
|
asciidoc section markup in the style guide (internal issue 898).
|
|
* Fix <<spirvenv,SPIR-V appendix>> to say
|
|
code:VariablePointersStorageBuffer instead of
|
|
code:VariablePointersUniformBufferBlock (internal issue 928).
|
|
|
|
Other Commits:
|
|
|
|
* Add missing extension structures to dependency attributes in +vk.xml+.

Change log for July 15, 2017 Vulkan 1.0.55 spec update:
|
|
|
|
* Bump API patch number and header version number to 55 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Removed unintended optional parameter in +vk.xml+ from the
|
|
pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted
|
|
in the generation of an incorrect implicit valid usage clause allowing
|
|
pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is
|
|
non-zero (public issue 491).
|
|
* Add missing attribute to +vk.xml+ documenting that
|
|
slink:VkSwapchainCounterCreateInfoEXT extends
|
|
slink:VkSwapchainCreateInfo (public issue 510).
|
|
* Add const qualifier for some `VK_EXT_debug_market` extension command
|
|
parameters that were missing it (public issue 513).
|
|
* Fix definition of q and level~base~ in
|
|
<<textures-image-level-selection,Image Level(s) Selection>> (public
|
|
issue 515).
|
|
* Clarify lifetime requirement for slink:VkRenderPass objects used in
|
|
object creation (public issue 516).
|
|
* Fix link to floating/normalized fixed-point conversion from
|
|
<<interfaces-fragmentoutput,Fragment Output Interface>> (public issue
|
|
521).
|
|
|
|
Internal Issues:
|
|
|
|
* Update the style guide to include the general structure of a Vulkan
|
|
command name, the specific rule for using "`Get`" vs. "`Enumerate`" in
|
|
names, and a table of verbs commonly used in command names (spinoff of
|
|
internal issue 753).
|
|
* Clarified the behavior of automatic layout transitions in case of
|
|
attachment views that are 2D or 2D array views of 3D images. In
|
|
addition, restructured the valid usage clauses corresponding to the
|
|
members of the slink:VkImageSubresourceRange structure and added missing
|
|
valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer
|
|
members (internal issues 803, 849).
|
|
* Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a
|
|
push_constant declaration (internal issue 919).
|
|
|
|
Other Commits:
|
|
|
|
* Modify <<synchronization-framebuffer-regions, Framebuffer Region
|
|
Dependencies>> to use synchronization scope terminology.
|
|
* Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the
|
|
`VK_EXT_swapchain_colorspace` extension.
|
|
* Replace XML comments with `comment` attributes and/or tags, to enable
|
|
tools which transform the XML without loss of information.
|
|
* Replace `validextensionstructs` with `structextends`, which is tagged in
|
|
the child structure instead of the parent. This makes it slightly
|
|
simpler to add new structs to the XML, causes fewer merge conflicts, and
|
|
the information is kept localized to the extension structures where it
|
|
belongs. The old `validextensionstructs` attributes will be retained
|
|
until we're certain this doesn't cause problems with known consumers of
|
|
+vk.xml+.

Internal Issues:
|
|
|
|
* Fix tessellation domain to have an upper-left origin in the
|
|
<<img-tessellation-topology-ul, tessellation toplogy image>> and related
|
|
language. CTS and all implementations were already doing this, it was
|
|
just a documentation bug that it was flipped to lower-left (internal
|
|
issue 603).
|
|
* Add a section to the style guide describing how VUID tags are changed
|
|
and removed when the corresponding Valid Usage statements are modified
|
|
(internal issue 829).
|
|
* Add explicit Valid Usage statement to
|
|
slink:VkPipelineDynamicStateCreateInfo to require that members of
|
|
pname:pDynamicStates must be unique (internal issue 851).

Github Issues:
|
|
|
|
Internal Issues:
|
|
|
|
* Clarify mappings of coordinates for mutable, compatible image views in
|
|
slink:VkImageViewCreateInfo (internal issue 815).
|
|
* Make ename:VK_BIND_SFR_BIT require a logical device with multiple
|
|
physical devices, so that standard sparse image block dimensions are
|
|
only required on systems that support multi-GPU (internal issue 835).
|
|
* Convert all files from use of // refBegin .. // refEnd comments to
|
|
delimit ref pages, to use of open blocks, and update style guide
|
|
accordingly (internal issue 839).
|
|
* Add valid usage for slink:VkWriteDescriptorSet when performing updates
|
|
to a ename:VK_STORAGE_IMAGE descriptor with layout
|
|
ename:VK_IMAGE_LAYOUT_GENERAL.
|
|
* Add a hack to the validity generator script to support an odd
|
|
interaction between flink:vkCmdFillBuffer and an extension (internal
|
|
issue 853).
|
|
* Remove redundant text describing slink:VkBufferCreateInfo::pname:usage,
|
|
which was already covered by implicit valid usage (internal issue 854).
|
|
* Update implicit validity generator script to properly handle the
|
|
pname:sType and pname:pNext members of "returnedonly" structures
|
|
(internal issue 874).
|
|
* Note that slink:VkApplicationInfo::pname:pApplicationName &
|
|
slink:VkApplicationInfo::pname:pEngineName are optional, and add missing
|
|
implicit valid usage statements for flink:vkDestroyInstance.
|
|
* Added missing valid usage for flink:vkCmdWriteTimestamp to require a
|
|
timestamp query pool.
|
|
* Simplify and/or split "`non-atomic`" valid usage statements.
|
|
|
|

Change log for June 13, 2017 Vulkan 1.0.52 spec update:
|
|
|
|
* Bump API patch number and header version number to 52 for this update.
|
|
|
|
Github Issues:
|
|
|
|
Internal Issues:
|
|
|
|
* Clarify behavior when non-coherent memory has
|
|
<<memory-device-unmap-does-not-flush, not been flushed before being
|
|
unmapped>> (internal issue 819).
|
|
* Fix description of code:WorkgroupSize builtin to note it decorates an
|
|
object, not a variable (internal issue 836).
|
|
* Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style
|
|
equations are rendered properly (internal issue 845).
|
|
* Add language to the "`Extension Handles, Objects, Enums, and Typedefs`"
|
|
section of the Procedures and Conventions document stating that any new
|
|
handle type requires a corresponding entry in the elink:VkObjectType
|
|
enumerated type (internal issue 856).
|
|
* Update style guide to use slink macro for Vulkan handle type names, and
|
|
define narrow conditions under which to use the *name and *text macros
|
|
instead of *link (internal issue 886).
|
|
* Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>>
|
|
extension on VK_KHX_device_group_creation to +vk.xml+ and the extension
|
|
appendix.
|
|
* Change the copyright on Vulkan specification asciidoc *source* files to
|
|
CC-BY 4.0, and update the proprietary Khronos copyright applied to the
|
|
generated *output* formats (internal issue 327). This enables broader
|
|
re-use and modification of the Vulkan specification sources, while not
|
|
affecting the Reciprocal IP License between Vulkan Adopters and Working
|
|
Group Members.

Change log for June 4, 2017 Vulkan 1.0.51 spec update:
|
|
|
|
* Bump API patch number and header version number to 51 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Add Valid Usage statement to flink:vkCmdResolveImage to require that
|
|
source and destination image formats match (public issue 492).
|
|
* Specify that a code:char* parameter must: be a valid null-terminated
|
|
string in the <<fundamentals-implicit-validity, implicit valid usage>>
|
|
section (public issue 494).
|
|
* Removed unnecessary VU for slink:VkPhysicalDeviceFeatures which is
|
|
covered by ename:VK_ERROR_FEATURE_NOT_PRESENT already (public issue
|
|
496).
|
|
* Clarify valid usage of pname:pQueueFamilyIndices in
|
|
slink:VkBufferCreateInfo, slink:VkImageCreateInfo, and
|
|
slink:VkSwapchainCreateInfoKHR (public issue 501).
|
|
* Document that dependencies of enabled extensions must also be enabled in
|
|
the <<extended-functionality-extensions-dependencies, Extension
|
|
Dependencies>> section (public issue 507).
|
|
|
|
Internal Issues:
|
|
|
|
* Change slink:VkMappedMemoryRange valid usage to allow pname:offset +
|
|
pname:size == size of the allocation. Also, if ename:VK_WHOLE_SIZE is
|
|
used, require the end of the mapping to be aligned to a multiple of
|
|
pname:nonCoherentAtomSize (internal issue 611).
|
|
* Add issue to `VK_KHR_win32_surface` about reusing window objects from a
|
|
different graphics API or Vulkan ICD (internal issue 639).
|
|
* Require locations on user in/out in `GL_KHR_vulkan_glsl` (internal issue
|
|
783).
|
|
* Added version info to the json validation output, and updated the schema
|
|
to match (internal issue 838).
|
|
* Restructure enumerated type descriptions separately from the command or
|
|
structure they are used in, allowing better reference page generation
|
|
(internal issue 841).
|
|
* Re-sort extension appendices to be in alphabetical order within each
|
|
author ID section.
|
|
* Fix enum naming and clarify behavior for
|
|
`VK_NVX_device_generated_commands` extension.

Change log for May 20, 2017 Vulkan 1.0.50 spec update:
|
|
|
|
* Bump API patch number and header version number to 50 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Fix numerous minor issues with the VK_EXT_debug_report extension (public
|
|
issues 478, 483, 486, 489, 490).
|
|
|
|
Internal Issues:
|
|
|
|
* Update flink:vkAllocateDescriptorSets to specify conditions under which
|
|
to return ename:VK_ERROR_FRAGMENTED_POOL or
|
|
ename:VK_ERROR_OUT_OF_POOL_MEMORY instead of
|
|
out-of-host/out-of-device-memory, and improve the
|
|
<<fundamentals-errorcodes, description of those errors (internal issue
|
|
654).
|
|
* Add a NOTE documenting that flink:vkAcquireNextImageKHR can only signal
|
|
a single semaphore, and how to deal with that when multiple physical
|
|
devices in a logical device need to wait on it (internal issue 730).
|
|
* Improve description of pname:pNext chains of
|
|
slink:VkPhysicalDeviceImageFormatInfo2KHR and
|
|
slink:VkImageFormatProperties2KHR (internal issue 814).
|
|
* Clean up math markup issues in the <<textures, Image Operations>>
|
|
chapter (internal issue 818).
|
|
* Update validusage target to use more robust code for preprocessing, by
|
|
making direct use of Asciidoctor's preprocessor. Added uniqueItems check
|
|
to JSON vu schema and add clean_validusage target (internal issue 826).
|
|
* Update style guide to prohibit writing non-self-contained (on a single
|
|
bullet point) Valid Usage statements, and modify offending Valid Usage
|
|
statements in the Specification to match, to assist with automatic
|
|
extraction for the validation layers (internal issue 828).
|
|
* Add ename:VK_VALIDATION_CHECK_SHADERS_EXT to elink:VkValidationCheckEXT
|
|
of the `VK_EXT_validation_flags` extension, to selectively disable
|
|
shader validation.
|
|
* Remove duplicate valid usage statement for slink:VkImageMemoryBarrier.
|
|
* Modify reflow.py script to place VUID tag anchors standalone on a line
|
|
following their corresponding bullet point, and reflow the spec text
|
|
accordingly (this had been pending since the initial tag deployment).
|
|
|
|
New Extensions:
|
|
|
|
* `VK_AMD_texture_gather_bias_lod`

Change log for May 12, 2017 Vulkan 1.0.49 spec update:
|
|
|
|
* Bump API patch number and header version number to 49 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Modify reference page extraction script to make internal links to spec
|
|
anchors refer to the core specification instead of being dangling links
|
|
(public issue 455).
|
|
* Fix GL_KHR_vulkan_glsl typo and add a nor-normative mapping to the newly
|
|
published StorageBuffer class (public issue 466).
|
|
* Both flink:vkEnumerateInstanceExtensionProperties and
|
|
flink:vkEnumerateDeviceExtensionProperties return
|
|
ename:VK_ERROR_LAYER_NOT_PRESENT, which covers the error case of an
|
|
application providing a layer name that wasn't returned by
|
|
ftext:vkEnumerate{Instance|Device}LayerProperties (public issue 487).
|
|
* The specification for flink:VkApplicationInfo::apiVersion says that the
|
|
driver must return ename:VK_ERROR_INCOMPATIBLE_DRIVER in the case that
|
|
pname:apiVersion specifies a non-supported version. That means that the
|
|
valid usage should not also state that, and so the VU statement is
|
|
removed. The VU had language about "`an effective substitute`" that
|
|
would have been lost, and so it was moved to the pname:apiVersion
|
|
description (public issue 488).
|
|
|
|
Internal Issues:
|
|
|
|
* Modify implicit validity generator script to assign asciidoc anchors to
|
|
all valid usage statements it generates, and reflow.py script to insert
|
|
Valid Usage ID (VUID) tags into the specification source files for
|
|
explicit valid usage statements. This has no semantic effects on the
|
|
specification, but will support the validation layer's detection of
|
|
valid usage violations and allow it to link into the corresponding part
|
|
of the specification (internal issue 583).
|
|
* Assign VUID tags to all explicit VU statements and document
|
|
the process and tag format in the style guide (internal issue 583).
|
|
* Clarify the rules of whether to structure new functionality as instance
|
|
extensions, device extensions, or both in the
|
|
<<extended-functionality-instance-extensions-and-devices, Instance
|
|
Extensions and Device Extensions>> section (internal issue 749).
|
|
* Require that SPIR-V run-time arrays are only used with the
|
|
code:BufferBlock decoration (internal issue 750).
|
|
* Fix implicit and explicit valid usage statements for
|
|
slink:VkWriteDescriptorSet::pname:dstSet (internal issue 767)
|
|
* Fix SPIR-V code sample for ename:VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER
|
|
in the <<descriptorsets-uniformtexelbuffer, Uniform Texel Buffer>>
|
|
section (internal issue 770).
|
|
* Clarify that disabling depth testing also disables depth writes in the
|
|
<<fragops-ds-state, Depth and Stencil Operations>> section (internal
|
|
issue 775).
|
|
* flink:VkDescriptorImageInfo::pname:imageLayout must match the actual
|
|
imageLayout at the time the image is accessed. This was in the spec
|
|
text, but needed an associated valid usage statement.
|
|
* Note that only 32-bit atomic operations are supported in the
|
|
<<spirvenv-module-validation, Validation Rules within a Module>>
|
|
section.
|
|
* Note that code:UniformConstant variables must not have initializers in
|
|
the <<spirvenv-module-validation, Validation Rules within a Module>>
|
|
section.
|
|
* Add a new elink:VkObjectType enumeration to the core API, promoted from
|
|
elink:VkDebugObjectTypeEXT, since it is used for much more than just the
|
|
debug_report extension.
|
|
|
|
New Extensions:
|
|
|
|
* `VK_KHR_get_surface_capabilities2`
|

|
|
Internal Issues:
|
|
|
|
* Add missing VU statements for flink:vkUpdateDescriptorSets (internal
|
|
issue 333).
|

* Correct swapped ifdef/ifndef blocks for `VK_KHR_maintenance1` extension
|
|
(internal issue 776).

Change log for April 8, 2017 Vulkan 1.0.47 spec update:
|
|
|
|
* Bump API patch number and header version number to 47 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Allow <<synchronization-pipeline-barriers-subpass-self-dependencies,
|
|
self-dependencies>> (also described for slink:VkSubpassDependency) to
|
|
have earlier stages depend on later stages if all stages are
|
|
framebuffer-space (public issue 125).
|
|
* Clarify when pipeline state structures are ignored in the
|
|
slink:VkGraphicsPipelineCreateInfo strucure, when the tessellation
|
|
structure must be valid, and remove 'if `NULL`' descriptions from the
|
|
valid usage statements (public issue 445).
|
|
* Remove the obsolete "validextensionstructs" attribute for
|
|
flink:VkPresentRegionsKHR. This caused a pname:pNext valid usage
|
|
statement to be generated which wasn't consistent with what is stated in
|
|
the spec (public issue 481).
|
|
|
|
Internal Issues:
|
|
|
|
* Clarify facingness of non-polygon fragments for slink:VkStencilOpState
|
|
and in the code:FrontFacing <<interfaces-builtin-variables,built-in
|
|
variable description>>. Define 'facingness' of a fragment as a distinct
|
|
term from facingness of a polygon (internal issue 662).
|
|
* Clarify that the texture compression features (e.g.
|
|
pname:textureCompressionBC) means that all formats of that type
|
|
(<<features-features-textureCompressionASTC_LDR,ASTC>>,
|
|
<<features-features-textureCompressionETC2,ETC2>>,
|
|
<<features-features-textureCompressionBC,BC>>) are supported, and that
|
|
support for individual formats may: queried separately (internal issue
|
|
663).
|
|
* Clarify in the valid usage for slink:VkBindImageMemoryInfoKHX that each
|
|
SFR rectangle must be a multiple of the sparse block size for each
|
|
aspect, e.g. in a depth/stencil image using separate depth/stencil
|
|
planes (internal issue 721).
|
|
* Re-remove KHX variants of KHR structure types after promotion (internal
|
|
issue 762).

|
Change log for March 31, 2017 Vulkan 1.0.46 spec update:
|
|
|
|
* Bump API patch number and header version number to 46 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Add language to the <<fundamentals-validusage-enums, Valid Usage for
|
|
Enumerated Types>> section allowing values to be returned from Vulkan
|
|
that are not present in extensions explicitly enabled by the
|
|
application, similar to existing language for bit flags in the
|
|
<<fundamentals-validusage-flags, Valid Usage for Flags>> section (public
|
|
issue 442).
|
|
* *Important*: run `gem update --pre asciidoctor-pdf` before trying to
|
|
build this version of the spec - 1.5.0.alpha15 is required for this
|
|
change. Removes the monkey patch currently used to draw valid usage
|
|
blocks across multiple pages which had numerous issues. A fixed version
|
|
was incorporated into Asciidoctor-PDF for the latest release, so the
|
|
monkey patch or any variant thereof is no longer required (public issue
|
|
465).
|
|
|
|
Internal Issues:
|
|
|
|
* Add ename:VK_DEBUG_REPORT_OBJECT_TYPE_DESCRIPTOR_UPDATE_TEMPLATE_KHR_EXT
|
|
to `VK_EXT_debug_report` extension
|
|
* Fix ptext:pNext member of
|
|
slink:VkPhysicalDeviceDiscardRectanglePropertiesEXT to be a non-const
|
|
pointer. Properties structures return values, so the chain should be
|
|
non-const.
|
|
* Explicitly remove gl_NumSamples from the `GL_KHR_vulkan_glsl` extension,
|
|
against 1.0 (internal issue 612).
|
|
* Add Valid Usage statements requiring that each structure type valid in a
|
|
ptext:pNext chain must: not appear more than once in a chain (internal
|
|
issue 752).
|
|
* Use ename:VK_USE_PLATFORM_WIN32_KHX in the
|
|
`VK_KHX_external_memory_win32` extension, rather than etext:_KHR
|
|
(internal issue 754).
|
|
|
|
New Extensions:
|
|
|
|
* `VK_KHR_incremental_present`

Change log for March 24, 2017 Vulkan 1.0.45 spec update:
|
|
|
|
* Bump API patch number and header version number to 45 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Defined the lifetime of the memory pointed to by
|
|
slink:VkDisplayPropertiesKHR::pname:displayName to be equal to that of
|
|
its associated display handle (public issue 460).
|
|
* Correct several cases where the sparse memory feature name
|
|
pname:residencyNonResidentStrict was written as
|
|
pname:sparseResidencyNonResidentStrict (public issue 475).
|
|
|
|
Internal Issues:
|
|
|
|
* Fix ptext:pNext member of slink:VkPhysicalDeviceGroupPropertiesKHX to be
|
|
a non-const pointer. Properties structures return values, so the chain
|
|
should be non-const.
|
|
* Clarify definition of memory aliasing to consistently use the terms
|
|
"linear" and "non-linear" when referring to resources, and define what
|
|
those terms mean.
|
|
* Modified XML schema and implicit validity scripts to generate language
|
|
for all ptext:pNext values in a ptext:pNext chain instead of just the
|
|
top level struct, and made `noautovalidity` functional for ptext:sType
|
|
and ptext:pNext (internal issue 535).
|
|
* Add more detail for BT2020 and scRGB color spaces in
|
|
`VK_EXT_swapchain_colorspace` extension (internal issue 632).
|
|
* Add naming rules for Extension Structure Names (structures added to the
|
|
ptext:pNext chain of a base structure) to the style guide (internal
|
|
issue 706).
|
|
* Define the glossary term "ptext:pNext chain", and use it consistently in
|
|
the spec (internal issue 744).

|
flink:vkWaitForFences, and flink:vkGetFenceStatus (public issue 423).
|
|
* Clarify definition of flink:vkGetQueryPoolResults::pname:queryCount
|
|
(public issue 441).
|
|
* Simplify and clean up normative language. Remove shall and replace
|
|
recommend and variants with should wherever possible (public issue 448).
|
|
* Fix all dangling internal cross-references in the 1.0-extensions
|
|
specification, and add scripts/checkXrefs to find these in the future
|
|
(public issue 456).
|
|
* Reverse order of ChangeLog.txt entries so the most recent version is
|
|
documented first (public issue 463)
|
|
* Removes "become invalid" which clashes with invalid state for command
|
|
buffers. (public issue 467)
|
|
* Disallowed pending state in spec text for vkResetCommandBuffer, matching
|
|
valid usage (public issue 468)
|
|
* Removes sentence describing invalid state "like initial state". (public
|
|
issue 469)
|
|
* Disallows begin command buffer from resetting command buffers in the
|
|
"recording" state. (public issue 470)
|
|
* Removes mention of state from description of
|
|
VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT (public issue 471)
|

|
|
code from the specification and noted it has been moved to the Vulkan
|
|
SDK cube demo (internal issue 179).
|
|
* Reorder VkExternalMemoryHandleTypeFlagBitsNV description (internal issue
|
|
480).
|
|
* Clarify than an implementation is
|
|
<<fundamentals-validusage-flags,permitted to return 'undefined' bit
|
|
flags>> in a bitfield (internal issue 640).
|
|
* Break Valid Usage statements describing unrelated parameters into
|
|
separate statements, and add a style guide entry to follow this approach
|
|
(internal issue 685).
|
|
* Move valid usage statement for slink:VkImageCreateInfo from spec body to
|
|
the explicit valid usage block (internal issue 693).
|
|
* Fix typos in the descriptions of slink:VkDisplaySurfaceCreateInfoKHR,
|
|
flink:vkCreateDisplayModeKHR, and
|
|
flink:vkGetDisplayPlaneSupportedDisplaysKHR in the <<display,Presenting
|
|
Directly to Display Devices>> section (internal issue 698, 704, 716).
|
|
* Clarified that mandatory depth/stencil formats are only a requirement
|
|
for 2D images (internal issue 719).
|
|
* Clarify that variables decorated with DeviceIndex/ViewIndex must be in
|
|
the Input storage class (internal issue 733).
|

Change log for March 10, 2017 Vulkan 1.0.43 spec update:
|
|
|
|
* Bump API patch number and header version number to 43 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Make clearer that color write mask is applied regardless of whether
|
|
blending is enabled, by referring to the
|
|
<<framebuffer-color-write-mask,Color Write Mask>> section (public issue
|
|
241).
|
|
* Fix public issue 414:
|
|
** Added two new command buffer states (invalid, pending), and an explicit
|
|
"command buffer lifecycle" section to explain them.
|
|
** Replaced "pending execution" with "in the pending state".
|
|
** Replaced a bunch of "this will invalidate the command buffer" language
|
|
with "this will move the command buffer to the invalid state", and added
|
|
validation language for what state those command buffers should be in.
|
|
** Added additional validation language about what state a command buffer
|
|
should be in for various commands that affect it.
|
|
** Added invalidation language to destroy commands in the lifetimes section
|
|
of fundamentals.
|
|
** Added command buffers to list of objects which must not be deleted
|
|
whilst a (primary) command buffer is in the recording or pending state.
|
|
* Update `GL_KHR_vulkan_glsl` extension to allow anonymous push constant
|
|
blocks (public issue 428).
|
|
|
|
Internal Issues:
|
|
|
|
* Document rules about extension interactions in the style guide (internal
|
|
issue 579).
|
|
* Require ename:VK_PRESENT_MODE_MAILBOX_KHR support in queries of surfaces
|
|
created with flink:vkCreateWaylandSurfaceKHR using the
|
|
VK_KHR_wayland_surface extension (internal issue 666).
|
|
* Remove Valid Usage constraints for flink:vkAllocateDescriptorSets when
|
|
the `VK_KHR_maintainance1` extension is present (internal issue 686).
|
|
* Remove undocumented KHX-variants of vkGetPhysicalDeviceProperties2KHR
|
|
and vkGetPhysicalDeviceImageFormatProperties2KHR from the
|
|
<<VK_KHX_external_memory_capabilities>> and
|
|
<<VK_KHX_external_semaphore_capabilities>> extensions.
|
|
|

Change log for February 27, 2017 Vulkan 1.0.42 spec update:
|
|
|
|
* Bump API patch number and header version number to 42 for this update
|
|
(the first anniversary edition).
|
|
|
|
Github Issues:
|
|
|
|
* Changed asciidoctor macros so cross-page links in the standalone
|
|
reference pages function properly (public issue 462).
|
|
|
|
Internal Issues:
|
|
|
|
* Clarified host visibility discussion for slink:VkMemoryType,
|
|
flink:vkInvalidateMappedMemoryRanges, elink:VkAccessFlagBits, and the
|
|
<<synchronization-framebuffer-regions,Framebuffer Region Dependencies>>
|
|
section, removing duplicated information and adding a central definition
|
|
in the access types section (internal issue 552).
|
|
* Change description of
|
|
slink:vkGetPhysicalDeviceSurfacePresentModesKHR::pname:pPresentModes to
|
|
return an array of values, not structures (internal issue 699).
|
|
|
|
New Extensions:
|
|
|
|
* Add a NOTE to the <<extensions,Layers & Extensions>> chapter describing
|
|
the experimental status of `KHX` extensions.
|

Change log for February 17, 2017 Vulkan 1.0.41 spec update:
|
|
|
|
* Bump API patch number and header version number to 41 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Made all uses of `NULL` vs. code:VK_NULL_HANDLE consistent (public issue
|
|
276).
|
|
* Clarify render pass compatibility in different usage scenarios (public
|
|
issues 403 and 404).
|
|
* Add valid usage statements to slink:VkFramebufferCreateInfo requiring
|
|
that the width, height, and number of layers of the framebuffer all be
|
|
nonzero (public issue 432).
|
|
* Allow `offset` and `align` in any GLSL version for the
|
|
`GL_KHR_vulkan_glsl` extension (public issue 435).
|
|
* Specify lifetime of string objects passed to the
|
|
tlink:PFN_vkDebugReportCallbackEXT user callback in the
|
|
+VK_EXT_debug_report+ extension (public issue 446).
|
|
* Fix inter-page links in multi-file reference pages (public issue 454).
|
|
|
|
Internal Issues:
|
|
|
|
* Update valid usage language for slink:VkImageCreateInfo to disallow
|
|
creating images that have ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT
|
|
set without other attachment usage bits
|
|
(ename:VK_IMAGE_USAGE_INPUT_ATTACHMENT_BIT,
|
|
ename:VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT, or
|
|
ename:VK_IMAGE_USAGE_DEPTH_STENCIL_ATTACHMENT_BIT) (internal issue 540).
|
|
* Disable `VK_EXT_swapchain_colorspace` extension until internal issues
|
|
640 and 661 are mutually resolved.
|
|
* Allow alternative mipmap level selection when [eq]#lambda == 0.5# during
|
|
texture <<textures-image-level-selection,Image Level(s) Selection>>
|
|
(internal issue 680).
|
|
|
|
Other Issues:
|
|
|
|
* Add a clarification to the style guide that the extension revision
|
|
number is treated as a patch number, so that changes to published
|
|
extensions should only include bug fixes and spec clarifications.
|
|
|
|
-----------------------------------------------------
|
|
|
|
Change log for February 10, 2017 Vulkan 1.0.40 spec update:
|
|
|
|
* Bump API patch number and header version number to 40 for this update.
|
|
* There is a major build change in this release. We are now using the
|
|
Ruby-based ``asciidoctor'' implementation, rather than the Python-based
|
|
``asciidoc'' implementation, to process the specification. While the
|
|
actual specification markup changes were minimal, this requires a new
|
|
set of build tools and a very different installation process, especially
|
|
because we now use an experimental direct-to-PDF backend for Asciidoctor
|
|
instead of Docbook->dblatex->PDF. It is no longer possible to build the
|
|
Specification using asciidoc. See doc/specs/vulkan/README.adoc
|
|
for some guidance on installing the new toolchain components.
|
|
* There are some minor rendering issues in the PDF output due to teething
|
|
problems with the asciidoctor toolchain, especially with mathematical
|
|
equations. We are aware of these and working on them.
|
|
|
|
Github Issues:
|
|
|
|
* Updated sample code for the <<sparsememory-examples-basic,sparse
|
|
resource binding example>> (public issue 97).
|
|
* Modify line and point clipping behavior in the
|
|
<<vertexpostproc-clipping, Primitive Clipping>> section to allow for
|
|
pop-free behavior. The ability to check for which behavior is
|
|
implemented may be added a future feature or extension (public issue
|
|
113).
|
|
* Unify the discussions of implicit ordering throughout the spec, in
|
|
particular in the new sections <<drawing-primitive-order, Primitive
|
|
Order>>, <<primrast-order, Rasterization Order>>, and
|
|
<<synchronization-implicit, Implicit Synchronization Guarantees>>; the
|
|
discussion of <<synchronization-submission-order, submission order>>;
|
|
and references elsewhere to these sections (public issue 133).
|
|
* Clarify \<\<descriptorsets-compatibility,Pipeline Layout Compatibility>>
|
|
language and introduce the term ``identically defined'' (public issue
|
|
164).
|
|
* Add a dependency to the +VK_EXT_debug_marker+ extension that's needed to
|
|
reuse the object type enum from +VK_EXT_debug_report+, and moves the
|
|
definition of that enum into +VK_EXT_debug_report+ where it should be
|
|
(public issue 409).
|
|
* Remove redundant valid usage statement from slink:VkImageBlit (public
|
|
issue 421).
|
|
* Update GL_KHR_vulkan_glsl to allow the ternary operator to result in a
|
|
specialization constant (public issue 424).
|
|
* Fix valid usage for flink:VkPipelineShaderStageCreateInfo (public issue
|
|
426).
|
|
* Correct typo in New Objects list for <<VK_EXT_debug_report>> (public
|
|
issue 447).
|
|
|
|
Internal Issues:
|
|
|
|
* Moved to asciidoctor for spec builds (internal issue 121).
|
|
* Update style guide to describe where to put new extensions-specific
|
|
asciidoc files, and what to name them (internal issue 626).
|
|
* Add src/spec/indexExt.py to autogenerate registry index entries linking
|
|
into the 1.0-extensions specification, instead of maintaining the index
|
|
manually. (internal issue 642).
|
|
* Autogenerate extension dependencies and lists of all extensions and all
|
|
KHR extensions from the "supported" attributes in +vk.xml+. Execute
|
|
+make config/extDependency.sh+ from +doc/specs/vulkan+ when a supported
|
|
extension is added to vk.xml, to regenerate the dependency script. The
|
|
consequence is that specifying a single extension to the +makeExt+
|
|
script will automatically enable all extensions it depends on as well,
|
|
and that the +makeAllExts+ and +makeKHR+ scripts do not need to be
|
|
updated when a new extension is supported (internal issue 648).
|
|
* Put extension appendices all at the same asciidoc section level, so KHR
|
|
WSI extensions show up in the HTML index (internal issue 648).
|
|
|
|
Other Issues:
|
|
|
|
* Imbed images in the generated HTML specs instead of loading them from
|
|
the images/ directory.
|
|
* Fix missing EXT in extension name
|
|
(ename:VK_EXT_SWAPCHAIN_COLOR_SPACE_EXTENSION_NAME).
|
|
* Add new +VK_EXT_SMPTE_2086_metadata+ extension.
|
|
* In the <<platformCreateSurface_xlib,Xlib Surface>> section of the
|
|
`VK_KHR_xlib_surface` specification, add language warning users that
|
|
they always need to call code:XinitThreads.
|
|
* Use the term "presentable image" (rather than "swapchain image")
|
|
consistently in `VK_KHR_swapchain` and related extensions, and add a
|
|
glossary term defining it.
|
|
* Relocate the valid usage for samples of
|
|
flink:vkGetPhysicalDeviceSparseImageFormatProperties2KHR::pname:pFormatInfo
|
|
to be below the flink:VkPhysicalDeviceSparseImageFormatInfo2KHR
|
|
structure.

|
|
|
Change log for January 23, 2017 Vulkan 1.0.39 spec update:
|
|
|
|
* Bump API patch number and header version number to 39 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Clarified that only accesses via the specified buffer/image subresource
|
|
ranges are included in the access scopes (public issue 306).
|
|
* Add missing valid usage statements for flink:vkCreateComputePipelines
|
|
and flink:vkCreateGraphicsPipelines (public issue 427).
|
|
|
|
Internal Issues:
|
|
|
|
* Add a Note to the <<invariance,Invariance>> appendix about a difference
|
|
between OpenGL and Vulkan with regards to how primitives derived from
|
|
offsets are handled (internal issue 355).
|
|
* Add the +<<VK_KHR_get_physical_device_properties2>>+,
|
|
+<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+
|
|
extensions (internal issue 448).
|
|
* Add the +<<VK_EXT_shader_subgroup_vote>>+ and
|
|
+<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449).
|
|
* Update the texture level-of-detail equation in the
|
|
<<textures-scale-factor,Scale Factor Operation>> section to better
|
|
approximate the ellipse major and minor axes (internal issue 547).
|
|
* Forbid non-explicitly allowed uses of interface decorations in the
|
|
introduction to the <<interfaces,Shader Interfaces>> chapter (internal
|
|
issue 607).
|
|
* Replace use of MathJax with KaTeX, for improved load-time performance as
|
|
well as avoiding the scrolling-and-scrolling behavior due to MathJax
|
|
asynchronous rendering when loading at an anchor inside the spec. This
|
|
change also requires moving to HTML5 output for the spec instead of
|
|
XHTML, and there is a visible difference in that the chapter navigation
|
|
index is now in a scrollable sidebar instead of at the top of the
|
|
document. We may or may not retain the nav sidebar based on feedback
|
|
(internal issue 613).
|
|
* Improve consistency of markup and formatting in extension appendices
|
|
(internal issue 631).
|
|
|
|
Other Issues:
|
|
|
|
* Add explicit valid usage statements to slink:VkImageCopy requiring that
|
|
the source and destination layer ranges be contained in their respective
|
|
source and destination images.
|
|
* Add valid usage language for swapchain of flink:vkAcquireNextImage. If
|
|
the swapchain has been replaced, then it should not be passed to
|
|
flink:vkAcquireNextImage.
|
|
* Add a valid usage statement to flink:vkCreateImageView, that the image
|
|
must have been created with an appropriate usage bit set.
|
|
* Noted that slink:VkDisplayPresentInfoKHR is a valid extension of
|
|
slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section.
|
|
* Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor
|
|
to account for the multiple viewport feature. If the feature is not
|
|
enabled, the parameters for these functions have required values that
|
|
are defined in the <<features-features-multiViewport,multiple
|
|
viewports>> section of the spec but were not reflected in the valid
|
|
usage text for these functions.
|
|
* Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common
|
|
color spaces.
|
|
|

|
Change log for December 16, 2016 Vulkan 1.0.38 spec update:
|
|
|
|
* Bump API patch number and header version number to 38 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Make ename:VK_PIPELINE_STAGE_HOST_BIT invalid for all stage masks,
|
|
except for flink:vkCmdWaitEvents (public issue 261).
|
|
|
|
Internal Issues:
|
|
|
|
* Added validation language for flink:vkQueueBindSparse,
|
|
slink:VkPresentInfoKHR, and slink:VkSubmitInfo, and a note to the
|
|
<<synchronization-semaphores-waiting,Semaphore Waiting and Unsignaling>>
|
|
section to clarify that semaphores must be signaled and waited on in a
|
|
1:1 fashion (internal issue 546).
|
|
* Modify valid usage for slink:VkBufferImageCopy to only require
|
|
pname:bufferOffset to be a multiple of the image format's element size
|
|
when the format is not depth/stencil (internal issue 594).
|
|
|
|
Other Issues:
|
|
|
|
* Vulkan is now a registered trademark symbol, and this is reflected in
|
|
documents and copyright statements.
|
|
|

Change log for December 10, 2016 Vulkan 1.0.37 spec update:
|
|
|
|
* Bump API patch number and header version number to 37 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Add usability guarantees on the values returned by
|
|
flink:vkGetPhysicalDeviceSurfaceCapabilitiesKHR in the
|
|
slink:VkSurfaceCapabilitiesKHR structure and by
|
|
flink:vkGetPhysicalDeviceSurfaceFormatsKHR in the
|
|
pname:pSurfaceFormatCount parameter (public issue 385).
|
|
* Add elink:VkDebugReportObjectTypeEXT enumerants for new object types
|
|
introduced by new extensions (public issue 408).
|
|
* Add +VK_NVX_device_generated_commands+ etext:ACCESS bits and define how
|
|
they are used (public issue 415).
|
|
* Fix indentation for slink:VkDebugReportCallbackCreateInfoEXT member
|
|
descriptions (public issue 419).
|
|
|
|
Internal Issues:
|
|
|
|
* Expand requirements memory binding of non-sparse images and buffers from
|
|
the <<resources-association,Resource Memory Association>> section into
|
|
valid usage statements for all of the applicable API calls (internal
|
|
issue 508).
|
|
* Explicitly state that valid usage of flink:vkCreateImage requires that
|
|
flink:vkGetPhysicalDeviceImageFormatProperties would return
|
|
ename:VK_SUCCESS for the requested image configuration (internal issue
|
|
598).

Change log for December 1, 2016 Vulkan 1.0.36 spec update:
|
|
|
|
* Bump API patch number and header version number to 36 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Fix "recorded with" terminology in the valid usage language for the
|
|
flink:vkCmdExecuteCommands::pname:pCommandBuffers parameter (public
|
|
issue 390).
|
|
* Modify +genvk.py+ to support specifying extensions to remove from output
|
|
generators, allowing the extension loader +vulkan_ext.c+ to be created
|
|
without WSI extensions which are statically exported by the Vulkan
|
|
loader (public issue 412).
|
|
* Added validation language for slink:VkSubpassDependency and in the
|
|
<<synchronization-access-types-supported,supported access types>>
|
|
section to catch access masks that include bits which are not supported
|
|
by pipeline stages in the stage masks (partially addresses
|
|
github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers/issues/1006 ).
|
|
|
|
Internal Issues:
|
|
|
|
* Added validation language for flink:vkCmdWaitEvents,
|
|
flink:vkQueueSubmit, flink:VkRenderPassCreateInfo, and in the
|
|
<<synchronization-pipeline-stages-supported>> section to prevent
|
|
recording stage dependencies that aren't supported on the queue
|
|
(internal issue 516).
|
|
* Make a few changes that generalize spec language for use with possible
|
|
future extensions by adding glossary terms and generalizing ``feature''
|
|
to ``feature or extension'' where relevant (internal issues 448, 590).
|
|
* Added "pipeline type" attribute to +vk.xml+ for relevant commands and
|
|
utilize it in automatic generation of the Command Properties table
|
|
(internal issue 517).
|
|
* Specify that WSI implementations must provide both UNORM and sRGB
|
|
formats in the description of slink:VkColorSpaceKHR (internal issue
|
|
529).
|
|
* Remove nesting of explicit valid usage statements where it is not
|
|
meaningful (internal issue 583).
|
|
|
|
Other Issues:
|
|
|
|
* Add validity language requiring that
|
|
slink:VkPushConstantRange::pname:offset be a multiple of 4, as stated in
|
|
the spec language.

Change log for November 25, 2016 Vulkan 1.0.35 spec update:
|
|
|
|
* Bump API patch number and header version number to 35 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Document in the <<memory-device-hostaccess,Host Access>> section that
|
|
mapping and unmapping does not invalidate or flush the mapped memory
|
|
(public issues 27, 126).
|
|
* Redefine the entire <<synchronization>> chapter in terms of consistent
|
|
and well defined terminology, that's called out at the start of the
|
|
chapter. This terminology is applied equally to all synchronization
|
|
types, including subpass dependencies, submissions, and much of the
|
|
implicit ordering stuff dotted around the spec. Key terms are laid out
|
|
in the <<synchronization-dependencies,Execution and Memory
|
|
Dependencies>> section at the top of the rewritten chapter (public
|
|
issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407).
|
|
* Specify order of submission for batches in the
|
|
<<vkQueueSubmit,vkQueueSubmit>> and
|
|
<<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371).
|
|
* Add valid usage statements to each of the WSI extension sections
|
|
indicating that the WSI-specific structure parameters must be valid, and
|
|
remove automatically generated valid usage statements now covered by the
|
|
manual sections (public issue 383).
|
|
* Clarify render pass compatibility for flink:vkCmdExecuteCommands (public
|
|
issue 390).
|
|
|
|
Internal Issues:
|
|
|
|
* Update +vk.xml+ to make previously explicit valid usage statements for
|
|
<<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead
|
|
(internal issue 553).
|
|
* Add valid usage statement for slink:VkCreateImageInfo preventing
|
|
creation of 1D sparse images (internal issue 573).
|
|
* Fix Python scripts to always read/write files in utf-8 encoding, and a
|
|
logic error in reflib.py which could cause a fatal error for
|
|
malstructured asciidoc (internal issues 578, 586).

Change log for November 18, 2016 Vulkan 1.0.34 spec update:
|
|
|
|
* Bump API patch number and header version number to 34 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Allow vkUpdateDescriptorSets overflow to skip empty bindings. Clarify
|
|
that unused bindings have a descriptorCount of zero. Improve some valid
|
|
usage for vkUpdateDescriptorSets (public issue 256).
|
|
* Require that slink:VkImageSubresourceRange always define a non-empty
|
|
range of the resource (public issue 303).
|
|
* Added valid usage for slink:VkPresentInfoKHR on the layout of presented
|
|
images (public issue 397).
|
|
|
|
Internal Issues:
|
|
|
|
* Add dependency in src/spec/Makefile so specversion.txt is regenerated
|
|
when needed (internal issue 462).
|
|
* Shorten the table of contents in the single-page ref page HTML output.
|
|
Still working on the PDF (internal issue 536).

Change log for November 11, 2016 Vulkan 1.0.33 spec update:
|
|
|
|
* Bump API patch number and header version number to 33 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Added implicit external synchronization parameters to
|
|
vkBegin/EndCommandBuffer, and fixed missing command pool host
|
|
synchronization from per-command lists (public issue 398).
|
|
* Started using git tags including the spec release number, such as
|
|
'v1.0.32-core', instead of tags including the date of release, such as
|
|
'v1.0-core-20161025' (public issue 405).
|
|
|
|
Internal Issues:
|
|
|
|
* Add validity constraint for
|
|
slink:VkImportMemoryWin32HandleInfoNV::pname:handle (internal issue
|
|
#480).
|
|
* Add scripts to compare two Vulkan HTML specifications, derived from W3
|
|
htmldiff service (internal issue 525).
|
|
* Relax requirement that memoryTypeBits can't depend on format, to allow
|
|
it to differ only for depth/stencil formats (internal issue 544).
|
|
* Add a new generator script to create a simple extension loader for
|
|
Vulkan based on +vk.xml+ (internal issue 558).
|
|
* Add the overlooked requirement that buffer and image memory
|
|
alignment requirements must be a power of two in the
|
|
<<resources-association,Resource Memory Association>> section
|
|
(internal issue 569).
|
|
|
|
Other Issues:
|
|
|
|
* Add a naming rule to the style guide for members of extension structures
|
|
defining array lengths which are the same as array lengths of the core
|
|
structure they are chained from.
|
|
* Add a new generator to create a simple extension loader in
|
|
+src/ext_loader/vulkan_ext.[ch]+ from +vk.xml+. This code can be
|
|
included in your project, and is expected to be packaged in the Vulkan
|
|
SDK provided by LunarG in the future.

Change log for October 25, 2016 Vulkan 1.0.32 spec update:
|
|
|
|
* Bump API patch number and header version number to 32 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Add automatic visibility operations to the presentation engineE when
|
|
doing a queue present in flink:vkAcquireNextImageKHR. Removed all
|
|
references to MEMORY_READ that referenced WSI - they no longer make
|
|
sense (some aspects of public issues 128, 131, 132, 261, and 298).
|
|
* Document valid non-boolean +externsync+ attribute values for <param>
|
|
tags in +vk.xml+ (public issue 265).
|
|
* Add valid usage to slink:VkImageCreateInfo requiring that
|
|
pname:arrayLayers be 1 for images of type ename:VK_IMAGE_TYPE_3D
|
|
(public issue 319).
|
|
* Add missing captions to figures in the <<textures,Image Operations>>
|
|
chapter (public issue 334).
|
|
* Clarify WSI interaction with exclusive sharing mode (public issue
|
|
344).
|
|
* Added explicit language clarifying the allowed queue usage of
|
|
resources created with ename:VK_SHARING_MODE_CONCURRENT (public
|
|
issue 386).
|
|
* Require that the
|
|
slink:VkDescriptorSetLayoutCreateInfo::pname:binding members of the
|
|
pname:pBindings array passed to
|
|
flink:vkDescriptorSetLayoutCreateInfo all be distinct (public issue
|
|
391).
|
|
|
|
Internal Issues:
|
|
|
|
* Remove empty validity blocks from +vk.xml+ and suppressed broken
|
|
validity statements and added missing statements to explicit
|
|
validity. Doesn't affect output, other than some statements
|
|
appearing in another block now (internal issue 513).
|

|
|
Change log for October 14, 2016 Vulkan 1.0.31 spec update:
|
|
|
|
* Bump API patch number and header version number to 31 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Clarifying wording of slink:VkGraphicsPipelineCreateInfo parameters and
|
|
adding Valid Usage statements on render pass compatibility to the
|
|
<<drawing,drawing commands>> (public issue 375).
|
|
* Replace 'texel size' with 'element size', and add a definition to the
|
|
glossary (public issue 382).
|
|
* Clarify the description of ename:VK_ERROR_NATIVE_WINDOW_IN_USE_KHR to
|
|
make it accurate, but still generic (non-exhaustive). Remove two Valid
|
|
Usage statements describing error situations that will return
|
|
ename:VK_ERROR_NATIVE_WINDOW_IN_USE_KHR (public issue 387).
|
|
* Fix refBegin tag for elink:VkDebugReportFlagBitsEXT (public issue 392).
|
|
* The <<interfaces-builtin-variables,built-in variable>> code:PrimitiveId
|
|
in a fragment shader needs the code:Input storage class (public issue
|
|
393).
|
|
|
|
Internal Issues:
|
|
|
|
* Unused ({y,z} and {height,depth} for 1D, z and depth for 2D) offsets
|
|
must be 0 and unused extents must be 1. Added basic offset and extent
|
|
valid usage for slink:VkImageResolve to match that of slink:VkImageCopy
|
|
(internal issue 413).
|
|
* Describe what flink:vkGetPhysicalDeviceImageFormatProperties returns for
|
|
pname:sampleCounts when for pname:usage only includes transfer-related
|
|
flags (internal issue 478).
|
|
* Remove mention of
|
|
slink:VkPhysicalDeviceLimits::pname:maxImageArrayLayers from the valid
|
|
usage for slink:VkImageCreateInfo::pname:arrayLayers (internal issue
|
|
520).
|
|
* Tag usages of ``dynamically uniform'' as glossary terms and add a
|
|
glossary entry pointing to the SPIR-V Specification's definition of the
|
|
term (internal issue 531).
|
|
|

Change log for October 7, 2016 Vulkan 1.0.30 spec update:
|
|
|
|
* Bump API patch number and header version number to 30 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Document missing pname:sType and pname:pNext parameters for
|
|
slink:VkCommandBufferInheritanceInfo (public issue 224).
|
|
* As promised, we are removing the example code, from the appendix, for
|
|
the VK_KHR_surface and VK_KHR_swapchain extensions. The cube demo
|
|
(shipped in the official Khronos SDK) has been updated, and is the
|
|
example code that we want people to look at for how to use these two
|
|
extensions (public issues 279, 308, and 311).
|
|
* Clarify the formats for which the slink:VkClearColorValue pname:float32
|
|
member is used. Also clean up related language for flink:vkCmdBlitImage
|
|
(public issue 369).
|
|
* Reword the <<invariance, Invariance>> appendix chapter to better match
|
|
Vulkan terminology (public issue 372).
|
|
|
|
Internal Issues:
|
|
|
|
* Update slink:VkMemoryRequirements to not require a host_visible memory
|
|
type exists that can be bound to sparse buffers (internal issue 494).
|
|
* Modify the <<features-supported-sample-counts,Supported Sample Counts>>
|
|
language to allow multisampled depth-stencil images (internal issue
|
|
521).
|
|

Change log for September 30, 2016 Vulkan 1.0.29 spec update:
|
|
|
|
* Bump API patch number and header version number to 29 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Remove redundant constraint on
|
|
slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue
|
|
224).
|
|
* Fix typo and remove link in Note in the
|
|
<<extended-functionality-instance-extensions-and-devices, Instance
|
|
Extensions and Device Extensions>> section (public issue 359).
|
|
* Fix erroneous validation statement for the pname:layout member of
|
|
slink:VkComputePipelineCreateInfo (public issue 362).
|
|
|
|
Internal Issues:
|
|
|
|
* Restore long figure captions using asciidoc sidebar blocks, due to
|
|
restrictions of asciidoc syntax (internal issue 101).
|
|
* Replace most latexmath equations with comparable markup in straight
|
|
asciidoc, which significantly improves time required to fully load and
|
|
process the HTML forms of the Specification. There are known minor font
|
|
and alignment inconsistencies with MathJax and PDF rendering of
|
|
latexmath equations. Please do not file github issues about these. We
|
|
are aware of the inconsistencies and will make refinements over time,
|
|
while the performance improvements are compelling in at least some major
|
|
browsers (internal issue 313).
|
|
* Move handcoded validity statements from +vk.xml+ into the Specification
|
|
body, easing work in the single-branch model. Specify the distinction
|
|
between these explicit statements, and the implicit validity statements
|
|
inferred from vk.xml. Validity statements now appear in two blocks for
|
|
each command and structure - handcoded "Valid Usage" and the implicit
|
|
"Valid Usage (Implicit)" (internal issue 392).
|
|
* Add the +returnedonly="false"+ attribute to WSI output structures,
|
|
removing incorrectly generated implicit validity statements for
|
|
slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR,
|
|
slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR,
|
|
slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures
|
|
(internal issue 486).
|
|
* Update slink:VkImageLayout to require the
|
|
ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images
|
|
(internal issue 487).
|
|
* Use an explicit format specifier string for the date command invocation
|
|
in the +Makefile+ instead of the shorthand -R option, which doesn't work
|
|
on BSD and MaxOS X date commands (internal issue 500).
|
|
|
|
Other Issues:
|
|
|
|
* Use the terms ``allocation scope'' and ``extension scope'' instead of
|
|
just ``scope'', and add them to the glossary.
|
|

Change log for September 23, 2016 Vulkan 1.0.28 spec update:
|
|
|
|
* Bump API patch number and header version number to 28 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Minor spelling and typography cleanup, add definitions of
|
|
ename:VK_FALSE and ename:VK_TRUE as just what their names say
|
|
(public issues 220, 318, 325, 365; internal issues 451, 496)
|
|
* Clarify that the pname:maxDescriptorSet limits in the
|
|
<<features-limits-required,Required Limits>> table are n *
|
|
maxPerStage limit (where n=number of supported stages) (public issue
|
|
254).
|
|
* Minor cleanup to <<boilerplate-platform-macros,Platform-Specific
|
|
Macro Definitions>> appendix (public issue 314).
|
|
* Add valid usage statement to slink:VkPipelineLayoutCreateInfo
|
|
disallowing multiple push constant ranges for the same shader stage
|
|
(public issue 340).
|
|
* Clarify the elink:VkSharingMode description of what executing the
|
|
"same" barriers means in case of ownership transfer (public issue
|
|
347).
|
|
* Rename copyright.txt and add COPYING.md to try and reduce confusion
|
|
about applicable copyrights (public issue 350).
|
|
* Extend the table in the <<boilerplate-wsi-header, Window System-Specific
|
|
Header Control>> section to describe the external headers included when
|
|
each etext:VK_USE_PLATFORM_* macro is defined (public issue 376).
|
|
|
|
Internal Issues:
|
|
|
|
* Add "Revision History" to the PDF outputs following the table of
|
|
contents, to match HTML outputs (internal issue 43).
|
|
* Clarified that flink:vkMapMemory may fail due to virtual address
|
|
space limitations (internal issue 346).
|
|
* Add +refBody+ comment markup for ref page autoextraction when required
|
|
(internal issue 400).
|
|
* Document proper use of "mipmap" and "mip" in the style guide API
|
|
naming rules, matching the spelling rules (internal issue 471).
|
|
* Tweak the <<extensions,Layers and Extensions>> appendix to note that
|
|
the Specification may be built with arbitrary combinations of
|
|
extensions (internal issue 483).
|
|
* Remove incorrect statement allowing
|
|
slink:VkClearAttachment::pname:colorAttachment to be >=
|
|
slink:VkSubpassDescription::pname:colorAttachmentCount (internal
|
|
issue 488).
|
|
* The <<features-limits-viewportboundsrange,viewportBoundsRange>> is
|
|
expressed in terms of the pname:maxViewportDimensions but this is
|
|
actually two values. Clarify that it's based on the larger of the two
|
|
(if they differ) (internal issue 499).
|
|
|
|
Other Issues:
|
|
|
|
* Reflowed text of the entire spec using the 'reflow' Makefile target, to
|
|
(hopefully) reduce future internal git churn as edits are made and
|
|
extensions added in return for one-time pain. This has no perceptible
|
|
effect on the spec outputs, but considerable changes on the asciidoc
|
|
source (internal issue 367).
|

Change log for September 16, 2016 Vulkan 1.0.27 spec update:
|
|
|
|
* Bump API patch number and header version number to 27 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Weaken flink:vkGetPipelineCacheData invariance conditions; previous
|
|
conditions were stronger than agreed and can't be guaranteed (public
|
|
issue 280).
|
|
* Add link to "Vulkan Loader Specification and Architecture Overview"
|
|
document to Normative References section (public issue 359).
|
|
|
|
Internal Issues:
|
|
|
|
* Be more clear in the <<interfaces-resources-layout-std140, uniform
|
|
buffer layout>> section that block offsets can be out of order
|
|
(internal issue 396).
|
|
* Document that extension authors should add support for their extensions
|
|
to the validation layers (internal issue 398).
|
|
* Clarify that the valid range of depth clear values should be limited
|
|
to the 0..1 range and that copies to depth aspect must also be in this
|
|
range (internal issue 412).
|
|
* Specify ``a'' vs. ``an'' use in the style guide (internal issue 432).
|
|
* Increase the maximum pname:nonCoherentAtomSize value in the
|
|
<<features-limits-required,Required Limits>> section from 128 to 256
|
|
(internal issue 435).
|
|
* Fix vk_platform.h for compiler errors on some Android platforms
|
|
(internal issue 441).
|
|
* Clarify that slink:VkPhysicalDeviceFeatures::pname:pEnabledFeatures ==
|
|
`NULL` disables all features, including the "required" feature
|
|
pname:robustBufferAccess (internal issue 479).
|
|
|
|
Other Issues:
|
|
|
|
* Expand style guide and make it more self-consistent.
|
|
* Use ISO 8601 date format everywhere.
|
|
* Emphasise the correct way of using
|
|
slink:VkSurfaceCapabilitiesKHR::pname:maxImageCount.
|
|
* Added +VK_EXT_validation_flags+ extension for validation flag mechanism.
|
|
* Fix an <<credits,author credit>> to include their current employer.

Change log for September 6, 2016 Vulkan 1.0.26 spec update:
|
|
|
|
* Bump API patch number and header version number to 26 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Bring sample code in the `VK_KHR_surface` and `VK_KHR_swapchain`
|
|
extension summary appendices up to date, and note they will be replaced
|
|
with pointers to the LunarG SDK examples in the future (public issue
|
|
279).
|
|
* Add a new <<fundamentals-commandsyntax-results-lifetime,Lifetime of
|
|
Retrieved Results>> section specifying that ftext:vkGet* and
|
|
ftext:VkEnumerate* results are invariant unless otherwise specified, and
|
|
specify behavior for individual commands which are not invariant (public
|
|
issue 280).
|
|
* Remove conflicting definition of
|
|
slink:VkDisplayPlaneCapabilitiesKHR::pname:maxSrcPosition and clean up
|
|
language of the remaining definition (public issue 351).
|
|
* Fix many minor spelling errors and add rules to the style guide to
|
|
prevent recurrences (public issue 352).
|
|
|
|
Internal Issues:
|
|
|
|
* Remove redundant descriptions of the etext:VK_USE_PLATFORM_* macros from
|
|
the <<wsi,Window System Integration>> chapter in favor of the
|
|
description in the <<boilerplate-wsi-header,Window System-Specific
|
|
Header Control>> appendix (internal issue 6).
|
|
* Replace misleading 'can: be destroyed when not X' with more correct
|
|
'must: not be destroyed while X' in the
|
|
<<fundamentals-objectmodel-lifetime,Object Lifetime>> section. Disallow
|
|
destroying a pipeline layout while a command buffer using it is
|
|
recording (internal issue 241).
|
|
* Clarify that ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT is valid for
|
|
all images used as attachments in elink:VkImageUsageFlagBits and the
|
|
slink:VkImageLayout validity language (internal issue 320).
|
|
* Note that <<extended-functionality-layers,Layers>> may wrap object
|
|
handles, but that this is a generally discouraged. A link to additional
|
|
information in the documentation for layer authors is provided (issue
|
|
398)
|
|
* Replace the mustnot: and shouldnot: macros with equivalent must: not and
|
|
should: not to get rid of non-English words while still highlighting
|
|
normative language (internal issue 407).
|
|
* Disallow creating multisampled images with
|
|
ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT in the slink:VkImageLayout
|
|
validity language and the <<features-supported-sample-counts,Supported
|
|
Sample Counts>> section (internal issue 445).
|
|
* Fix typo so that flink:vkCmdDrawIndexedIndirect is defined in terms of
|
|
flink:vkCmdDrawIndexed rather than flink:vkCmdDrawIndirect (internal
|
|
issue 446).
|
|
* Reorganize the per-extension information sections to all be in the
|
|
<<extensions,Layers & Extensions>> appendix. Also fix a typo in
|
|
+VK_IMG_filter_cubic+ which incorrectly identified it as a +KHR+
|
|
extension (internal issue 461).
|
|
|
|
Other Issues:
|
|
|
|
* Use asciidoc markup instead of latexmath to simplify diagrams in the
|
|
<<features-formats-non-packed,byte mapping tables>> for color formats.
|
|
* Fix a markup problem with the wildcarded enumerant names in a NOTE in
|
|
the <<textures-texel-replacement,Texel Replacement>> section.
|
|
* Fix missing attributes in the XML interface for
|
|
elink:VkExternalMemoryHandleTypeFlagBitsNV and
|
|
elink:VkExternalMemoryFeatureFlagBitsNV (KhronosGroup/Vulkan-Hpp issue
|
|
25)
|
|
* Cleanup reference page builds so only core pages are built for releases.

Change log for August 26, 2016 Vulkan 1.0.25 spec update:
|
|
|
|
* Bump API patch number and header version number to 25 for this update.
|
|
* Structurally change the specification so that multiple extensions are
|
|
included in the +1.0+ git branch, and specifications will include or not
|
|
include those extensions at build time based on options passed to the
|
|
Makefile. See +doc/specs/vulkan/README.html+ and the ``Layers and
|
|
Extensions'' section of the ``Vulkan Documentation and Extensions''
|
|
document for more information on this change.
|
|
* Register and publish new extensions in the single-branch form:
|
|
** +VK_NV_external_memory_capabilities+
|
|
** +VK_NV_external_memory+
|
|
** +VK_NV_external_memory_win32+
|
|
** +VK_NV_win32_keyed_mutex+

|
|
exception to the American spelling rules convention (public issue
|
|
327).
|
|
* Fix Makefile to create output directory for ``styleguide''
|

target (public issue 329).
|
|
* Fix numerous minor issues with incorrectly tags on enumerant names and
|
|
table titles (public issue 330).
|

|
|
flink:VkShaderModuleCreateInfo into an internal link to the normative
|
|
reference (public issue 336).
|
|
* Add ename:VK_ERROR_OUT_OF_MEMORY error code to
|
|
flink:vkCreateDebugReportCallbackEXT (public issue 337).
|
|
|
|
Internal Issues:
|
|
|
|
* Update style guide regarding use of code:NULL and dname:VK_NULL_HANDLE
|
|
(internal issue 393).
|
|
* Change the definition of latexmath:[$q$] in the
|
|
<<textures-image-level-selection,texture image level selection>> section
|
|
to be the index of the maximum defined level for the view, not the
|
|
number of levels in the view (internal issue 406).
|
|
* Allow developers to override dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE
|
|
with their own binary-compatible definition (internal issue 439).
|
|
* Fix +vk_platform.h+ conditional logic causing compile failure with some
|
|
Android compilers (internal issue 441).

Change log for August 12, 2016 Vulkan 1.0.24 spec update:
|
|
|
|
* Bump API patch number and header version number to 24 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Fix type mismatch in swapchain image equivalency table (public issue
|
|
289).
|
|
* Fix a copy-and-paste error in the description of
|
|
flink:vkGetSwapchainImagesKHR::pname:pSwapchainImages, that said it
|
|
was an array of ``sname:VkSwapchainImageKHR structures'' instead of
|
|
an array of ``sname:VkImage handles'' (public issue 292).
|
|
* Specify that ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT is only valid
|
|
for ename:VK_IMAGE_TYPE_2D images (public issue 293).
|
|
* Add a valid usage statement to flink:vkCmdExecuteCommands saying
|
|
that when called outside a render pass instance, the secondary
|
|
command buffers must not have been created with the
|
|
ename:VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT (public issue
|
|
297).
|
|
* Fix description of +VK_NO_STDINT_H+ in the
|
|
<<boilerplate-platform-macros,platform macros>> section (public
|
|
issue 314).
|
|
|
|
Internal Issues:
|
|
|
|
* Normalize the language for the remaining built-in variables in the
|
|
<<interfaces-builtin-variables,Built-In Variables>> section. Fix
|
|
code:FrontFacing and code:HelperInvocation, as they should be of
|
|
code:boolean type rather than code:integer (internal issue 323).
|
|
* Clarify that when ename:VK_WHOLE_SIZE is used for a buffer
|
|
descriptor range, the effective range must still be within the max
|
|
buffer range (internal issue 426).
|
|
* Clarify that command buffers and descriptor sets are allocated
|
|
rather than created. Also clarify when the recording state of a
|
|
command buffer is relevant (internal issue 434).
|
|

|
Change log for August 5, 2016 Vulkan 1.0.23 spec update:
|
|
|
|
* Bump API patch number and header version number to 23 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Add explicit valid value attributes to pname:sType members in vk.xml
|
|
(public issue 34).
|
|
* Clarify usage of flink:vkGetInstanceProcAddr and
|
|
flink:vkGetDeviceProcAddr (public issue 225).
|
|
* Fix a copy-and-paste error in the description of
|
|
pname:pSwapchainImageCount saying that it was the count of ``format
|
|
pairs'' instead of ``swapchain images'' (public issue 292).
|
|
* flink:vkCmdExecuteCommandBuffers requires all command buffers to be
|
|
allocated from command pools created for the same queue family (public
|
|
issue 296).
|
|
* Remove bogus +optional+ attribute for
|
|
flink:vkEnumerateDeviceLayerProperties::pname:physicalDevice from vk.xml
|
|
(public issue 301).
|
|
* Clean up the <<resources-image-views-compatibility,image and image view
|
|
compatibility table>> reference and contents. Use full enumerant names.
|
|
Refer to pname:layerCount in the ``view parameters'' column instead of
|
|
pname:arrayLayers. Require N >= 1 for the cube array subview row, not
|
|
just arrayLayers >= 6 N (public issue 304).
|
|
* Modify description of <<resources-memory-aliasing,memory aliasing>> to
|
|
be consistent with the description of
|
|
<<resources-bufferimagegranularity,buffer image granularity>> (public
|
|
issue 307).
|
|
|
|
Internal Issues:
|
|
|
|
* Describe remaining +vk_platform.h+ macros in the <<boilerplate,API
|
|
Boilerplate>> appendix (internal issue 6).
|
|
* Clarify
|
|
<<features-features-robustBufferAccess,pname:robustBufferAccess>>
|
|
feature behavior; what memory can be accessed, how bounds checking is
|
|
performed, and allowing for vectorization (internal issue 332).
|
|
* Document markup for automatic extraction of reference pages from the
|
|
spec sources in the style guide (internal issue 395).
|
|
* Allow flink:vkCreateDisplayModeKHR to return
|
|
ename:VK_ERROR_INITIALIZAION_FAILED_KHR if the user requests mode
|
|
parameters that the specified display does not support (internal issue
|
|
411).
|
|
* Remove atomic counters (atomic_uint style) from KHR_vulkan_glsl, and
|
|
more clearly remove the subroutine keyword alongside it (internal issue
|
|
421).
|
|
* Clarify behavior of flink:vkCmdBindDescriptorSets for descriptor sets
|
|
not contained in the layout (internal issue 427).
|
|
|
|
Other Commits:
|
|
|
|
* Change the order in which members of sname:VkAttachmentDescription and
|
|
sname:VkPipelineInputAssemblyStateCreateInfo are described to match
|
|
their order in the structures.

Change log for July 22, 2016 Vulkan 1.0.22 spec update:
|
|
|
|
* Bump API patch number and header version number to 22 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Translate the subpass self-dependency language into concrete
|
|
validity statements, and added a validity statement about the
|
|
restrictions on layout parameters (public issue 267).
|
|
* Add validity requirement that
|
|
slink:VkAttachmentDescription::pname:finalLayout and
|
|
slink:VkAttachmentReference::pname:layout must not be
|
|
ename:VK_IMAGE_LAYOUT_UNDEFINED or
|
|
ename:VK_IMAGE_LAYOUT_PREINITIALIZED (public issue 268).
|
|
* Clarify that slink:VkSubpassDescription::pname:pResolveAttachments
|
|
layouts are used. Make language consistent with other attachment
|
|
arrays (public issue 270).
|
|
* Changed 64-bit definition for
|
|
dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE to work for x32 platform in
|
|
+vk.xml+ and the resulting +vulkan.h+ (public issue 282).
|
|
* Add missing error return code for
|
|
flink:vkEnumerateInstanceExtensionProperties and
|
|
flink:vkEnumerateDeviceExtensionProperties (public issue 285)
|
|
* Fix several cases of stext::VkStructName.memberName markup to
|
|
stext::VkStructName::pname:memberName, to match other usage in the
|
|
spec, and describe this markup in the style guide (public issue
|
|
286).
|
|
* Modified validity language generation script to avoid redundant
|
|
common ancestor language if covered by generic parent language, and
|
|
used `Both' instead of `Each' when appropriate (public issue 288).
|
|
|
|
Internal Issues:
|
|
|
|
* Add language about behavior of flink:vkAllocateDescriptorSets when
|
|
allocation fails due to fragmentation, a new error
|
|
ename:VK_ERROR_FRAGMENTED_POOL, and a Note explaining the situation
|
|
(internal issue 309).
|
|
* For the features of code:PointSize, code:ClipDistance, and
|
|
code:CullDistance, the SPIR-V capability is required to be declared
|
|
on use (read or write) rather than on decoration (internal issue
|
|
359).
|
|
* Have desktop versions of GLSL respect precision qualification
|
|
(code:mediump and code:lowp) when compiling for Vulkan. These will
|
|
get translated to SPIR-V's code:RelaxedPrecision decoration as they
|
|
do with OpenGL ES versions of GLSL (ESSL). The default precision of
|
|
all types is code:highp when using a desktop version (internal issue
|
|
360).
|
|
* Add validity statement for slink:VkImageCreateInfo specifying that
|
|
multisampled images must be two-dimensional, optimally tiled, and
|
|
with a single mipmap level (internal issue 369).
|
|
* Add validity statements to slink:VkImageViewCreateInfo disallowing
|
|
creation of images or image views with no supported features. Made
|
|
some slink:VkImageViewCreateInfo validity statements more precise
|
|
and consistent. Added a Note to the <<features,features>> chapter
|
|
about formats with no features (internal issue 371).
|
|
* Remove +manpages+ from default build targets. Nroff outputs
|
|
containing imbedded latexmath will not render properly. Fixing this
|
|
is a lot of work for limited use cases (internal issue 401).
|
|
|
|
Other Commits:
|
|
|
|
* Fix flink:vkRenderPassBeginInfo::pname:clearValueCount validity
|
|
statement to be based on attachment indices rather than the number
|
|
of cleared attachments
|
|
(Vulkan-LoaderAndValidationLayers/issues/601).
|
|
* Convert registry documentation from LaTeX to asciidoc source and
|
|
rename from +src/spec/readme.tex+ to +src/spec/registry.txt+.
|
|
* Fix lack of Oxford commas in validity language.
|
|
* Lots of cleanup of generator scripts and Makefiles to move extension
|
|
list for generator into the script arguments instead of the body of
|
|
genvk.py, and express better dependencies between XML, scripts, and
|
|
generated files.

Change log for July 15, 2016 Vulkan 1.0.21 spec update:
|
|
|
|
* Bump API patch number and header version number to 21 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Clarify how <<features-supported-sample-counts,sample count queries>>
|
|
relate to the limits in slink:VkPhysicalDeviceLimits. (public issue
|
|
185).
|
|
* Clarify in the <<interfaces-iointerfaces,Shader Input and Output
|
|
Interfaces>> section that shader output variables have undefined values
|
|
until the shader writes to them (public issue 240).
|
|
* Specify the implicit value of image parameters that cannot be set in
|
|
slink:VkSwapchainCreateInfo::pname:flags, pname:imageType,
|
|
pname:mipLevels, pname:samples, pname:tiling, and pname:initialLayout
|
|
(public issue 243).
|
|
* Make use of code:NULL and code:VK_NULL_HANDLE consistent in the
|
|
VK_KHR_swapchain extension (public issue 276).
|
|
|
|
Internal Issues:
|
|
|
|
* Clarify that presenting an image to a display surface swapchain applies
|
|
the display surface's mode, and that destroying a display surface
|
|
swapchain may reset the display's mode, in the VK_KHR_display_swapchain
|
|
extension (internal issue 247).
|
|
* Better describe what a slink:VkSurfaceKHR is, and that creating one does
|
|
not set a mode, in the VK_KHR_display extension. This is a round-about
|
|
way of pointing out that mode setting is not covered by the extension,
|
|
but rather is performed as a side effect of presentation (internal issue
|
|
247).
|
|
* Add more valid usage statements to flink:vkQueuePresentKHR command when
|
|
the VK_KHR_display_swapchain extension is present (internal issue
|
|
247).
|
|
* Add more includes to the VK_KHR_swapchain extension to better document
|
|
interactions with VK_KHR_display_swapchain (internal issue 247).
|
|
* Clarify restrictions on location aliasing in the
|
|
<<fxvertex,Fixed-Function Vertex Processing>> section (internal issue
|
|
370).
|
|
* Add mathematical description of blitting to flink:vkCmdBlitImage, and
|
|
link it to the <<textures,Image Operations>> chapter. Use mathematical
|
|
notation for ranges of texel coordinates in the <<textures,Image
|
|
Operations>> chapter. Fixed miscellaneous validity statements for
|
|
flink:vkCmdBlit and slink:VkImageBlit (internal issue 382).
|
|
|
|
Other Commits:
|
|
|
|
* Added a valid usage rule to flink:VkGraphicsPipelineCreateInfo that the
|
|
ename:VK_PRIMITIVE_TOPOLOGY_PATCH_LIST topology must only be used when
|
|
tessellation shaders are used.
|
|
* Expand the style guide into a formal "Procedures and Conventions"
|
|
document. Add a API Naming Conventions section, move most of the API
|
|
Specification Appendix C (Layers and Extensions) content into the new
|
|
document, and define the resulting procedures as mandatory (where
|
|
relevant). This more clearly separates use vs. specification of Vulkan
|
|
APIs.
|
|
* Update vk_platform.h to handle 32-bit ARMv8 binaries.
|
|
* Various minor cleanups to the Makefile and build process.

Change log for July 8, 2016 Vulkan 1.0.20 spec update:
|
|
|
|
* Bump API patch number and header version number to 20 for this
|
|
update.
|
|
|
|
Github Issues:
|
|
|
|
* Replaced existing reference pages by text automatically extracted from
|
|
the specification source, or generated from vk.xml in some cases. This
|
|
is not a complete solution for the reference pages, but puts them in a
|
|
much better state. The ref pages (only) are now placed under a CC BY
|
|
open source license, which is more current than the obsolete license
|
|
previously used. Various minor tweaks to the Specification sources were
|
|
made to enable this, and a new ``API Boilerplate'' chapter added to
|
|
include definitions of all the entities in the API and +vulkan.h+ which
|
|
were not already described in some form in the document.
|
|
|
|
Further improvements to the pages should not edit them directly, but
|
|
instead concentrate on the specification source from which the ref pages
|
|
are being extracted (public issues 44, 55, 160; internal issue 389).

Change log for July 1, 2016 Vulkan 1.0.19 spec update:
|
|
|
|
* Bump API patch number and header version number to 19 for this
|
|
update.
|
|
|
|
Github Issues:
|
|
|
|
* Clarified how flink:vkGetImageSubresourceLayout interacts with image
|
|
layouts (public issue 247).
|
|
* Remove ename:VK_IMAGE_LAYOUT_PREINITIALIZED from valid usage rule for
|
|
slink:VkImageMemoryBarrier::pname:oldLayout. It is only valid if it is
|
|
the current layout (public issue 248).
|
|
* Modify valid usage for flink:vkBindBufferMemory so implementations are
|
|
free to require a different backing memory size than the buffer size
|
|
(public issue 251).
|
|
* Clarify that filtering rules for flink:vkCmdBlitImage always apply, and
|
|
are usually no-ops if the formats are the same (public issue 253).
|
|
* Remove 'non-sparse' from description of
|
|
flink:vkGetBufferMemoryRequirements and
|
|
flink:vkGetImageMemoryRequirements (public issue 257).
|
|
* Remove ename:VK_ERROR_LAYER_NOT_PRESENT error code from
|
|
flink:vkCreateDevice (public issue 259).
|
|
* Change "must: not" to "should: not" in constraint on when
|
|
flink:vkAcquireNextImageKHR is called in the VK_KHR_swapchain branch
|
|
(public issue 262).
|
|
* Change type of flink:vkCmdUpdateBuffer::pname:pData from
|
|
basetype:uint32_t* to basetype:void* (public issue 263).
|
|
* Change should: to must: in description of where additional segments are
|
|
placed in the <<[tessellation-tessellator-spacing,Tessellator Spacing>>
|
|
section (public issue 264).
|
|
|
|
Internal Issues:
|
|
|
|
* Normalize the language of all the compute shader built-ins in the
|
|
<<interfaces-builtin-variables,Built-in Variables>> section (internal
|
|
issue 323).
|
|
* Remove definition of presentation engine internal queue lengths
|
|
associated with ename:VK_PRESENT_MODE_FIFO_KHR and
|
|
ename:VK_PRESENT_MODE_FIFO_RELAXED_KHR in the <<Window System
|
|
Integration,wsi>> chapter (internal issue 374).
|
|
* The language of a Note was too broad, and implied that loaders for a
|
|
given OS would statically export functions for WSI extensions that
|
|
were not relevant to (or supported on) the OS. Also, removed
|
|
"Khronos-provided" since the Android loader is not (internal issue 380)
|
|
|
|
Other Commits:
|
|
|
|
* Add ename:VK_INCOMPLETE to list of return values for
|
|
flink:vkGetPipelineCacheData. Spec says this value is returnable, but it
|
|
was not listed in the error codes.
|
|
* Fix "correponds" typo in member definitions for
|
|
slink:VkSubpassDescription.

Change log for June 24, 2016 Vulkan 1.0.18 spec update:
|
|
|
|
* Bump API patch number and header version number to 18 for this
|
|
update.
|
|
|
|
Github Issues:
|
|
|
|
* Added "queue operation" terminology, and modified spec to actually
|
|
use this terminology (public issue 155). The act of submitting a
|
|
piece of work to a queue now generates "operations" for the queue to
|
|
execute, including operations to wait on/signal semaphores and
|
|
fences. Synchronization waits on these operations, making execution
|
|
dependency chains more obvious for semaphores and fences (though
|
|
additional work is still needed here). These changes include:
|
|
** Overview of "queue submission" commands in chapter
|
|
<<devsandqueues-submission>>.
|
|
** Updated descriptions for fence and semaphore waits and signals in
|
|
the synchronization chapter <<synchronization-semaphores-waiting>>,
|
|
<<synchronization-semaphores-signaling>> and
|
|
<<synchronization-fences-waiting>>.
|
|
** Clarifications to semaphore and fence operation within queue
|
|
submission functions.
|
|
** New glossary terms.
|
|
** Moved device idle and queue wait idle to synchronization chapter in
|
|
order to describe them in terms of other synchronization
|
|
primitives.
|
|
** Clarifications to semaphore and fence operation allowed removal of
|
|
the "implicit ordering guarantees" section, as this information is
|
|
now wholly covered where these primitives are described.
|
|
*** The "host writes" section of this is still there for now - in its
|
|
own section. This could probably be merged into other sections
|
|
later.
|
|
*** Modified fundamentals chapter on queue ordering to make sense in
|
|
context of the new changes, and avoid duplication.
|
|
<<fundamentals-queueoperation>>
|
|
* Added "aspect" and "component" definitions to the glossary, and made
|
|
sure these terms are referenced correctly (public issue 163).
|
|
* Update valid usage for ftext:vkGet*ProcAddr to only include
|
|
conditions that must be met to get a valid result. In particular,
|
|
it is okay to call flink:vkGetDeviceProcAddr with any string and will
|
|
get a code:NULL if that string is not a core Vulkan function or an
|
|
enabled extension function (addresses but does not fully close
|
|
public issue 214).
|
|
* Change the WSI extension dependencies to refer to version 1.0 of the
|
|
Vulkan API, instead of the pre-1.0-release internal revisions
|
|
numbers (public issue 238).
|

|
issue 52).
|
|
* Add logic to generate spec boilerplate without using the 'git'
|
|
command-line client, needed when building from a tarball or another
|
|
source of the Vulkan tree rather than a cloned git repo. Remove
|
|
boilerplate as part of 'clean' target (public issue 195).
|
|
* Document that color writes and clears to unused attachments have no
|
|
effect for slink:VkClearAttachment and
|
|
elink:VkColorComponentFlagBits (public issue 198).

|
(internal issue 109).
|
|
* Place WorkgroupSize in alphabetical order in the
|
|
<<interfaces-builtin-variables,Built-in Variables>> section
|
|
(internal issue 323).
|
|
* Corrects valid usage in vkEndRenderPass to only affect primary
|
|
render passes, as secondaries may be entirely within a render pass,
|
|
and should be able to be ended (previous language disallowed that)
|
|
(internal issue 338).
|
|
* Fix relational operator from <= to >= in the
|
|
<<features-extentperimagetype,Allowed Extent Values>> section
|
|
(internal issue 343).

|
issue 321).
|
|
* Fixes naming of the single elink:VkColorSpaceKHR enum from
|
|
ename:VK_COLORSPACE_SRGB_NONLINEAR_KHR to
|
|
ename:VK_COLOR_SPACE_SRGB_NONLINEAR_KHR in XML/header and the

|
|
166).

slink:VkImageCreateInfo validity language (public issue 184).
|
|
|
|
Internal Issues:
|
|
|
|
* Document that the requested patch version number specified as part
|
|
of slink:VkApplicationInfo::pname:apiVersion is ignored when
|
|
creating an instance (internal issue 176).
|
|
* Clarify handling of extension structs in the
|
|
<<fundamentals-validusageValid Usage>> section (internal issue 254).
|

|
|
be limited to the maximum allowed mipmap pyramid size corresponding
|
|
to the actual maximum supported size for the format (internal issue
|
|
256).
|
|
* Modify the <<features-extentperimagetype,Allowed Extent Values Based
|
|
On Image Type>> section so the allowed maximum extent is the maximum
|
|
image dimension supported for each dimension of the type of texture
|
|
being queried (internal issue 257).
|
|
* Clarify in the <<spirvenv-module-validation,Validation Rules within
|

update.
|
|
|
|
Github Issues:
|
|
|
|
* Slightly tweak the <<memory-allocation,Host Memory>> allocator language
|
|
so that an application wrapping the standard C alloc/free/realloc
|
|
functions is still correct - the previous language was too strong with
|
|
regards to freeing memory. Also made certain scenarios clearer - an
|
|
implementation may now continue without error if an allocation failed
|
|
and it is able to continue correctly (public issue 21).
|
|
* Require that etext:VK_*_CREATE_SPARSE_BINDING_BIT is set when the
|
|
corresponding etext:VK_*_CREATE_SPARSE_RESIDENCY_BIT is used, in the

|
the <<compute-shaders,Compute Shaders>> section to further clarify how
|
|
to set the number of workgroups to execute in a compute shader (public
|
|
issue 145).
|
|
* Use the term *image subresource* everywhere instead of *subresource*,
|
|
except for the special case of *host-accessible subresource*, which may
|
|
be either an image subresource or buffer range (public issue 120)
|
|
* Add a note to the <<features,Features, Limits, and Formats>> section
|
|
about extensibility of structures (Public issue 165).
|
|
* Fix return code flink:vkAcquireNextImageKHR when the timeout parameter
|
|

73).
|
|
* Clarify the WSI extension language by switching from the fuzzier
|
|
"ownership" language to more-consistent "acquire" language (public issue
|
|
117).
|
|
* Add language allowing allocation and freeing of memory scoped to the
|
|
duration of any API command in the <<memory-allocation,Memory
|
|
Allocation>> section (public issue 136).
|
|
* Clarify the explicit location assignment always overrides the inherited
|
|
location in the <<interfaces-iointerfaces-locations,Location
|
|
Assignment>> section, even for the first member of a block (public issue

* Change reference to the "lifetime" of a Vulkan command to
|
|
"duration", and define the "duration" term (public issue 135).
|
|
* Added valid usage language for slink:VkImageLayout to require both
|
|
pname:height and pname:depth to be 1 for 1D images and pname:depth
|
|
to be 1 for 2D images (public issue 137).
|
|
* Fix SPIR-V example code in the
|
|
<<descriptorsets-inputattachment,Input Attachment>> section to
|
|
properly decorate the code:InputAttachmentIndex (public issue 139).
|
|
* Fix reference to nonexistent pname:imageInfo in the description of
|
|
flink:VkWriteDescriptorSet to refer to pname:pImageInfo (public
|
|
issue 140).
|
|
|
|
Internal Issues:
|
|
|
|
* Link to the fixed-function vertex chapter from the drawing chapter
|
|
(internal issue 110)
|
|
* Fix typo in slink:VkImageCreateInfo validity language:
|
|
ptext:maxExtent.sampleCounts -> pname:sampleCounts (internal issue
|
|
249).
|
|
* Explain why the non-core token etext:VK_IMAGE_LAYOUT_PRESENT_SRC_KHR
|
|
is used in the example in the
|
|
<<synchronization-semaphores,Semaphores>> section (internal issue
|
|
251).
|
|
* Attempt to clarify in the VK_KHR_android_surface extension's
|
|
<<platformQuerySupport_android,Android Platform Support>> section
|
|
that there is no Android-specific WSI query, and why (internal issue
|
|
252).
|
|
|
|
Other Commits:
|
|
|
|
* Add missing language about ename:VK_INCOMPLETE being returned from
|
|
array queries when the passed array is too short, in the
|
|
VK_KHR_display, VK_KHR_swapchain, and VK_KHR_surface extensions.

|
Change log for March 25, 2016 Vulkan 1.0.7 spec update:
|
|
|
|
* Bump API patch number and header version number to 7 for this
|
|
update.
|
|
|
|
Github Issues:
|
|
|
|
* Fix slink:VkSpecializationMapEntry example to avoid C/C++ strict
|
|
aliasing issues (public issue 14).
|
|
* Clarify the meaning of "matching" in flink:vkCmdBindDescriptorSets
|
|
validity language (public issue 33).
|
|
* Add stub reference pages so xrefs to not-yet-written pages do not
|
|
generate 404 errors. However, the actual content of these pages
|
|
still needs to be filled in as time allows (public issue 44, but
|
|
does not close that issue out).
|
|
* Remove incorrect validity statement for
|
|
flink:vkGetImageSparseMemoryRequirements (public issue 85).
|
|
* Reword the
|
|
<<features-limits-bufferImageGranularity,bufferImageGranularity>>
|
|
feature in terms of "aliasing", and clarify that it applies to
|
|
bindings in the same memory object (public issue 90).
|
|
* Clarify the relationship of the slink:VkPhysicalDeviceLimits
|
|
pname:maxViewportDimensions and pname:viewportBoundsRange limits
|
|
(public issue 92).
|
|
* Specify sparse unbound texture replacement in the
|
|
<<textures-texel-replacement,Texel Replacement>> section
|
|
independently of robust buffer access language (public issue 100).
|
|
* Add the <<fundamentals-architecture-model,Architecture Model>>
|
|
section to explain architecture constraints Vulkan has chosen to
|
|
accept in order to enable portable and performant code (public issue
|
|
122).
|
|
* State that an object must not be destroyed until *all* (not *any*)
|
|
uses of that object have completed (public issue 123).
|
|
* Minor editorial cleanup (public issues 129, 134, 146, 148).
|
|
* Add validity language for layer and extension names to
|
|
slink:VkDeviceCreateInfo matching that used for
|
|
slink:VkInstanceCreateInfo (public issue 130).
|
|
* Clean up terminology for the case when the bits set in one bitmask
|
|
are a subset of the bits set in another bitmask (public issue 138).
|
|
* Document that input attachments are UniformConstant not Input, in
|
|
the <<interfaces-inputattachment,Fragment Input Attachment
|
|
Interface>> section (public glslang bug 169).
|
|
|
|
Internal Issues:
|
|
|
|
* Add max enum values to "flag bits" enums (internal issue 136).
|
|
* Clarify language around the various uses of the term "block" in the
|
|
<<appendix-compressedtex-bc,Block Compressed Image Formats>> section
|
|
(internal issue 202).
|
|
* Removed "expand" dependency from <enums> groups in vk.xml and added
|
|
auto-generation code in the scripts to infer it instead, to ensure
|
|
consistency. This caused renaming of sname:VkColorSpaceKHR and
|
|
sname:VkPresentModeKHR etext:BEGIN_RANGE (etc.) tokens, but those
|
|
tokens are metadata, not part of the API, and the Vulkan WG is OK
|
|
with this change. This change adds ranges to two additional enums
|
|
that were missing them due to not defining the "expand" attribute
|
|
(internal issue 217).
|
|
* Tweak makefile to generate ref page nroff (.3) files in the right
|
|
output directory, working around an a2x limitation (internal issue
|
|
223).
|
|
|
|
Other Commits:
|
|
|
|
* Add validity requirements for flink:vkCmdCopyQueryPoolResults
|
|
pname:dstBuffer parameter.
|
|
* Fix ref page build to generate .3 targets in the right output
|
|
directory.
|
|
|
|
-----------------------------------------------------
|
|
|
|
Change log for March 10, 2016 Vulkan 1.0.6 spec update:
|
|
|
|
* Bump API patch number and header version number to 6 for this
|
|
update.
|
|
|
|
Github Issues:
|
|
|
|
* Define 'invocation group' for compute and graphics shaders. Cleanup
|
|
definition and use of 'workgroup', and add glossary entries (public
|
|
issue 1).
|
|
* Various minor editorial fixes (public issue 33).
|
|
* Clarify locations for block members in the
|
|
<<interfaces-iointerfaces-locations,Location Assignment>>
|
|
section (public issue 45).
|
|
* Editorial fixes for <<commandbuffer-allocation,Command Buffer
|
|
Allocation>> section (public issues 54, 59).
|
|
* Clarify behavior of depth test in the <<fragops-depth,Depth Test>>
|
|
section (public issues 80, 81).
|
|
* Remove discussion of return codes from
|
|
flink:vkGetPhysicalDeviceSparseImageFormatProperties and
|
|
flink:vkGetImageSparseMemoryRequirements, which do not return values
|
|
(public issue 82).
|
|
* Allow flink:vkCmdDrawIndirect and flink:vkCmdDrawIndexedIndirect
|
|
pname:drawCount of 0, as well as 1, when the multiDrawIndirect
|
|
feature is not supported (public issue 88).
|
|
* Remove confusing wording in the <<features-limits,Limits>>
|
|
section describing the slink:VkPhysicalDeviceLimits
|
|
pname:minTexelBufferOffsetAlignment,
|
|
pname:minUniformBufferOffsetAlignment, and
|
|
pname:minStorageBufferOffsetAlignment members as both minimums and
|
|
maximums (public issue 91).
|
|
* Clarified that only the RGB components should be affected in places
|
|
where sRGB is referred to in the spec, such as ASTC formats. Minor
|
|
re-wording to avoid "color space" when actively incorrect, now that
|
|
we refer to the Data Format Spec which actually makes a distinction
|
|
between color space and transfer function (public issue 94).
|
|
* Treat pname:pPropertyCount == 0 consistently in
|
|
flink:vkEnumerateInstanceLayerProperties and
|
|
flink:vkEnumerateDeviceLayerProperties (public issue 99)
|
|
* Cleanup minor editorial issues in chapters 14-17 (public issue 100).
|
|
* Clarify definition of flink:vkEnumerateInstanceExtensionProperties
|
|
and flink:vkEnumerateDeviceExtensionProperties (public issue 101).
|
|
* Define the flink:vkEnumerateInstanceExtensionProperties and
|
|
flink:vkEnumerateDeviceExtensionProperties pname:pLayerName
|
|
parameter to be a pointer to a null-terminated UTF-8 string (public
|
|
issue 101).
|
|
* Rearrange "Missing information" references in mandatory format
|
|
tables (public issue 101).
|
|
* Clarify that the enumerated extensions returned by
|
|
flink:vkEnumerateInstanceExtensionProperties and
|
|
flink:vkEnumerateDeviceExtensionProperties will only include
|
|
extensions provided by the platform or extensions implemented in
|
|
implicitly enabled layers (public issue 101).
|
|
* Miscellaneous editorial fixes. Include the Vulkan spec patch number
|
|
in the PDF title. Fix label on <<fig-non-strict-lines,Non
|
|
strict lines>> diagram. Use more easily distinguished symbols in
|
|
tables in the <<features-required-format-support,Required
|
|
Format Support>> section. Do not require FQDNs used as layer names be
|
|
encoded in lower case if not possible, in the
|
|
<<extensions-naming-conventions, Extension and Layer Naming
|
|
Conventions>> section (public issues 101, 119, 121).
|
|
|
|
Internal Issues:
|
|
|
|
* Fixed excessive spacing in tables in XHTML (internal issue 18).
|
|
* Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT
|
|
applies to secondary command buffers. Previously spec only referred
|
|
to the members of pname:pCommandBuffers being affected by this bit.
|
|
Added a separate slink:VkSubmitInfo Valid Usage restriction
|
|
specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT
|
|
also applies to any secondary command buffers that are recorded into
|
|
the primary command buffers in pname:pCommandBuffers (internal issue
|
|
106).
|
|
* Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be
|
|
NULL (internal issue 117).
|
|
* Remove "the value of" where it is redundant (e.g. speaking of an API
|
|
parameter, struct member, or SPIR-V variable, but not when speaking
|
|
of color components) (internal issue 175).
|
|
* Forced patch version to always be 0 in the header. Add a
|
|
"VK_API_VERSION_<major>_<minor>" macro for people to use to do the
|
|
right thing. Add a VK_HEADER_VERSION which captures the header
|
|
release number independent of the spec patch number (internal issue
|
|
176).
|
|
* Correct description of
|
|
slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to
|
|
a null-terminated UTF-8 string" (internal issue 197).
|
|
|
|
Other Commits:
|
|
|
|
* Updated DataFormat spec reference to the new date for revision 5 of
|
|
that spec.
|
|
* Fixed KEEP option (to retain LaTeX intermediate files) in the
|
|
Makefile to be included when edited there, as well as set on the
|
|
command line.
|
|
* Reserve and add "VK_IMG_filter_cubic" to the registry, and implement
|
|
script functionality to add and remove validity from existing
|
|
functions. Includes schema and readme changes.
|
|
* Update GL_KHR_vulkan_glsl so push_constants do not have descriptor
|
|
sets.
|
|
|
|
-----------------------------------------------------
|
|
|
|
Change log for March 4, 2016 Vulkan 1.0.5 spec update:
|
|
|
|
* Bump API patch number to 5 for this update.
|
|
|
|
Github Issues:
|
|
|
|
* Correctly describe slink:VkPhysicalDeviceProperties pname:deviceName
|
|
member as a string, not a pointer to a string. Also one typo fix for
|
|
"hetereogeneous" (public issue 4).
|
|
* Replace maynot: macro with may: not, and "may: or maynot:" with
|
|
"may:" (public issue 4).
|
|
* Clarify that redundantly setting the state of a fence or event has
|
|
no effect (public issue 4).
|
|
* Minor fixes to ref pages to track descriptions of memory bits that
|
|
changed in the core spec. Fix name of a member in the description of
|
|
sname:sname:VkPipelineMultisampleStateCreateInfo (public issues 8,
|
|
13).
|
|
* Remove redundant validity statement for
|
|
sname:VkGraphicsPipelineCreateInfo::pname:stageCount (public issue
|
|
14).
|
|
* Fix typos in chapters 7-9 (public issue 14).
|
|
* Clarify the example demonstrating the behavior of
|
|
code:OpMemoryBarrier in the
|
|
<<shaders-execution-memory-ordering,shader memory acces
|
|
ordering>> section (public issue 16).
|
|
* Specify that freeing mapped memory implicitly unmaps the memory in
|
|
the description of flink:vkFreeMemory (public issue 17).
|
|
* Forbid allocation callbacks from calling into the API in the
|
|
<<memory-allocation,memory allocation>> section (public issue
|
|
20).
|
|
* Add missing validity rules about size being greater than 0 and
|
|
offset being less than size of object. Fix
|
|
flink:VkMappedMemoryRange's misinterpretation of offset (public
|
|
issues 27, 31).
|
|
* Add validity rule disallowing overlapping source/destination
|
|
descriptors in flink:VkCopyDescriptorSet (public issue 32).
|
|
* Clarify that array and matrix stride has to be a multiple of the
|
|
base alignment of the array or matrix in the
|
|
<<interfaces-resources-layout,Offset and Stride Assignment>>
|
|
section (public issue 38).
|
|
* Correct parenthesis floor nesting error in equation for
|
|
<<textures-RGB-sexp,RGB to shared exponent conversion>>.
|
|
Clarify case of when exp' is forced to 0, avoiding log2(0) undefined
|
|
problem (public issue 40).
|
|
* Remove redundant statement from the code:FragDepth description in
|
|
the <<interfaces-builtin-variables,Built-In Variables>>
|
|
section (public issue 47).
|
|
* Define the clamping of the
|
|
<<textures-level-of-detail-operation,bias added to the scale
|
|
factor>> by linking to the slink:VkPhysicalDevice feature
|
|
pname:maxSamplerLodBias (public issue 64).
|
|
* Fix typo "optimal linear resources" and clarify the set of resources
|
|
<<features-limits-bufferImageGranularity,the
|
|
pname:bufferImageGranularity resource>> applies to (public issue
|
|
67).
|
|
* Replace 'descriptor accessed by a pipeline' language for
|
|
sname:VkDescriptorSetAllocateInfo with more precise phrasing about
|
|
binding a descriptor set before a command that invokes work using
|
|
that set (public issue 69).
|
|
* tstripadj.svg contained an Inkscape tag which caused Firefox and IE
|
|
11 to fail to render it, and was illegal SVG. Generating Plain SVG
|
|
from the Inkscape SVG source fixes this (public issue 70).
|
|
* Fix validity for sname:VkVertexInputBindingDescription and
|
|
sname:VkVertexInputAttributeDescription numbers (public issue 72).
|
|
|
|
Internal Issues:
|
|
|
|
* Clarify the meaning of
|
|
ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT in
|
|
elink:VkFormatFeatureFlagBits with respect to depth compare
|
|
(internal issue 107).
|
|
* Added a note explaining that ename:VK_QUEUE_TRANSFER_BIT may or may
|
|
not be reported for a queue family that already supports
|
|
ename:VK_QUEUE_GRAPHICS_BIT or ename:VK_QUEUE_COMPUTE_BIT as the
|
|
former is a strict subset of the latter ones (internal issue 116).
|
|
* Add validity language for sname:VkDescriptorSetAllocateInfo about
|
|
exceeding the descriptor pool capacity (internal issue 140).
|
|
* Add ename:VK_INCOMPLETE success code for
|
|
flink:vkEnumeratePhysicalDevices query (internal issue 163).
|
|
|
|
Other Commits:
|
|
|
|
* Add the VK_NV_glsl_shader extension definitions to the API.
|
|
* Update GL_KHR_vulkan_glsl with 1) origin_upper_left as default 2)
|
|
specialization array constant semantics.
|
|
* Corrected/updated Data Format Specification date.
|
|
|
|
-----------------------------------------------------
|
|
|
|
Change log for February 25, 2015 Vulkan 1.0.4 spec update:
|
|
|
|
* Bump API patch number from 3 to 4 for the first public update to the
|
|
spec. Add patch number to the spec title (this will be done
|
|
automatically from XML, later).
|
|
* Fixes for numerous editorial issues. Regularize descriptions of
|
|
variable-length array queries. Properly tag enumerants so they come
|
|
out in the right font (many were mislabeled in usage tags in vk.xml,
|
|
or not tagged). Spelling and markup corrections (public issue 4).
|
|
* Fix typos and clearly separate description of different types of
|
|
memory areas (public issue 5).
|
|
* Use standards-compliant preprocessor guard symbols on headers
|
|
(public issue 7).
|
|
* Note that Github users cannot currently set labels on issues, and
|
|
recommend a fallback approach (public issue 15).
|
|
* Use latexmath prefix on len= attributes (public issue 29).
|
|
* Make flink:vkCmdUpdateBuffer pname:dataSize limit consistent (public
|
|
issue 65).
|
|
* Add VK_KHR_mirror_clamp_to_edge extension to core API branch, as an
|
|
optional feature not introducing new commands or enums (internal
|
|
issue 104).
|
|
* Cleanup invariance language inherited from the GL specification to
|
|
not refer to nonexistent (GL-specific) state (internal issue 111).
|
|
* Modify the flink:vkCmdDrawIndexed pname:vertexOffset definition to
|
|
not be the "base offset within the index buffer" but rather the
|
|
"value added to the vertex index before indexing into the vertex
|
|
buffer" (internal issue 118).
|
|
* Fix drawing chapter in the "Programmable Primitive Shading" section
|
|
where it described categories of drawing commands. It referenced
|
|
flink:vkCmdDrawIndexed twice. Replace the second reference with
|
|
flink:vkCmdDrawIndexedIndirect (internal issue 119).
|
|
* Typo fixed in <<sparsememory-examples-advanced,Advanced Sparse
|
|
Resources>> sparse memory example (internal issue 122).
|
|
* Add flink:VkDisplayPlaneAlphaFlagsKHR to <require> section of
|
|
VK_KHR_display extension (internal issue 125)
|
|
* Add missing optional="false,true" to
|
|
flink:vkGetImageSparseMemoryRequirements
|
|
pname:pSparseMemoryRequirementCount parameter (internal issue 132)
|
|
* Rename ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CREATE_INFO_EXT to
|
|
ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CALLBACK_CREATE_INFO_EXT
|
|
(internal issue 133)
|
|
* Fix a handful of broken cross-references in the
|
|
<<samplers,Samplers>> chapter (internal issue 134).
|
|
* Fix "Input Attachement" GLSL example to use correct syntax (internal
|
|
issue 135).
|
|
* Update XML schema and documentation to accommodate recently added
|
|
attributes for validity. Add some introductory material describing
|
|
design choices and pointing to the public repository to file issues.
|
|
* Put include of validity in the core spec extensions chapter on its
|
|
own line, so that asciidoc is happy.
|
|
* Fix vertexOffset language to specify that it is the value added to
|
|
the vertex index before indexing into the vertex buffer, not the
|
|
base offset within the index buffer.
|
|
* Fix error in the description of flink:vkCmdNextSubpass.
