- Make implicit validity for optional `void*` mean "nothing" in the
script
- Make `optional` mean non-NULL for `void*` (not implemented)
- Uses of `void*` that point to something should have `noautovalidity`
(adding it)
- Add missing explicit VUs of `void*` parameters
(`vkCmdPushDescriptorSetWithTemplateKHR` and
`vkUpdateDescriptorSetWithTemplateKHR`)
- Also indirectly fixes `vkMapMemory`, `VkAllocationCallbacks`,
`VkDebugReportCallbackCreateInfoEXT`, and Apple and NN surface create
- Remove ugly text hack from script
Previously
(`vkGetDeviceGroupSurfacePresentModesKHX::pModes` and
`vkGetDeviceGroupPeerMemoryFeaturesKHX::pPeerMemoryFeatures`)
required output flags pointer to be valid + non-0
* 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.
New Extensions:
* `VK_EXT_shader_stencil_export`
* Bump API patch number and header version number to 57 for this update.
Github Issues:
* Fix error in description of ename:VK_FORMAT_ETC2_R8G8B8A8_SRGB_BLOCK
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:
* `VK_AMD_mixed_attachment_samples`
* `VK_EXT_post_depth_coverage`
* `VK_KHR_relaxed_block_layout`
* `VK_NV_depth_range_unrestricted`
* 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+.
* Bump API patch number and header version number to 53 for this update.
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.
New Extensions:
* `VK_AMD_gpu_shader_int16`
* `VK_EXT_blend_operation_advanced`
* `VK_EXT_sampler_filter_minmax`
* `VK_NV_framebuffer_mixed_samples`
-----------------------------------------------------
Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release
combines both change sets.
-----------------------------------------------------
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.
New Extensions:
* `VK_NV_fill_rectangle`
* `VK_NV_fragment_coverage_to_color`
* 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.
New Extensions:
* 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`
* `VK_KHR_shared_presentable_image`
* 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`
* 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).
New Extensions:
* 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.
New Extensions:
* `VK_EXT_hdr_metadata`
* `VK_GOOGLE_display_timing`
* 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.
* 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 public issue
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.
* 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).
* 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.
* 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).
* 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.
* 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.
* 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+
Github Issues:
* Clarify description of GetInstanceProcAddr and GetDeviceProcAddr (public
issue 212).
* Add SPIR-V <<textures-operation-validation, instruction validation>> for
single-sampled images (public issue 316).
* Fix spelling of ``tesselation'' in a few places and note it as an
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).
* Generate specversion.txt date in UTC time and RFC 2822 format
(public issue 335).
* Convert link to the SPIR-V Specification for
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).
* Implement the single-branch model as described above (internal issue
461).
Other Issues:
* 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.
* 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.
* 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 isn't 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.
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).
