* 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`
* 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.
* 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`
- make implicit for `vkCmdSetViewport`
- make implicit for `vkCmdSetViewportWScalingNV`
- removed redundant explicit duplicate for `vkCmdSetDiscardRectangleEXT`
- remove redundant VU about the `pDiscardRectanges` vector; it is
implicit
- remove redundant VU about `firstDiscardRectangle` it is fully covered
by `00585` and implicit VU that says `discardRectangleCount` is greater
than 0
- remove redundant VU part saying >=1; it is implicit because of
`discardRectangleCount` > 0
- tweak `VkRect2D` VUs to mention the array they are part of
* 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_OPTIONAL 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`
- add missing `*name` and `*link` and `code`
- change where wrong macro was used
- swap `*name` and `*link` where appropriate
- correct misspelled names
- that sort of thing...
* 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).
Other Issues:
New Extensions:
- fixes rest of #416 (`VkImageSubresourceLayers`)
- migrate `VkImageSubresource` VUs where the state is known
- Simplify `VkImageSubresource` (`*count` always > 0)
1) Make explicit there is a <=> relationship between `DEVICE_LOCAL` heap
and `DEVICE_LOCAL` memory type
2) Make >4GB runtime error report mandatory. Otherwise it basically says
"do not pass >= 4GB, because possible undefined behavior".
3) Removed `VUID-vkAllocateMemory-device-00636`. Behavior is
deterministic returning `VK_ERROR_TOO_MANY_OBJECTS`
4) Moved `allocationSize` VU (depends on non-local state).
5) Changed `allocationSize`. Not sure what the original means, so
improvized a new one saying alloc size must be <= the whole size of the
heap.
6) Added VU restricting `memoryTypeIndex` to only the memory types of
the device.
1) Random grammar and formatting
2) Make example in first paragraph more
straightforward with elementary
Vulkan primitives (the original also
seemed factually wrong in places;
e.g. does UBO really have to be in
"on-device" memory?)
3) Removed unnecessary brandishing of obscure math
describing the memory
type list order. Tried something equally formal,
but more readable.
4) Made a note into a Note
5) Updated example.
Function names seem to be lower-case in the spec.
Hopefully made it bit
more readable. Turned the acompanying note into
the example content and
inline comments.
6) Removed redundant `VkDeviceMemory` intro
7) Break
out specifying language out of a Note
8) More straightforward description of `memoryTypeIndex`
* 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`
- fix `pretransform` and `compositeAlpha`; they are values not bitmasks
- update `imageFormat`, `imageColorSpace`, `imageUsage` and
`oldSwapchain` to be specific to behavior of this command
- fix broken unintended code block
- move `VK_TRUE` clipping text to correct bullet point
- random tweaks...
