* Update release number to 124.
Github Issues:
* Fix Makefile SPECREMARK macro to work when not building in a git tree
(public issue 992).
* Ignore pname:aspectMask for unused attachments in
slink:VkSubpassDescription2KHR valid usage statements (public pull
request 1028).
* Minor markup / spelling fixes (public pull requests 1035, 1045).
Internal Issues:
* Fix markup in Valid Usage statement for slink:VkCreateFramebuffer
(internal issue 1823).
* Add a new <<synchronization-signal-operation-order, _signal operation
order_>> section to the synchronization chapter which describes in
detail the ordering guarantees provided by the API between fence and
semaphore signal operations (internal merge request 3368).
* Move generated `appendix/meta/` files into the Makefile GENERATED
directory (internal merge request 3381).
New Extensions
* `<<VK_KHR_shader_clock>>`
* `<<VK_KHR_timeline_semaphore>>`
* Update release number to 121.
Github Issues:
* Add missing `structextends` attribute in `vk.xml` for
slink:VkPhysicalDevicePipelineExecutablePropertiesFeaturesKHR (public
issue 1018).
* Change attributes of flink:vkCmdCopyAccelerationStructureNV,
flink:vkCmdWriteAccelerationStructuresPropertiesNV,
flink:vkCmdBuildAccelerationStructureNV, and flink:vkCmdTraceRaysNV to
require that these commands execute outside renderpasses (public issue
1021).
* Add an issue to the `<<VK_EXT_buffer_device_address>>` appendix
discussing the introduction of new names and aliasing by equivalent old
names (public pull request 1024).
Internal Issues:
* Protect the `VK_KHR_sampler_mirror_clamp_to_edge` extension with
asciidoctor conditionals, and remove it from the core-only specification
builds, where it had previously been force-included in the Makefile. It
is now treated like any other extension (internal issue 1776).
* Edit some asciidoctor anchor names starting with `features-features-` to
just start with `features-`, since the old chapters was split into 3
pieces. There are still some mild naming inconsistencies with anchors
which may be addressed in the future (internal issue 1792).
* Add `KHR` alias for the non-suffixed extension token
ename:VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE, for compatibility
with naming rules for extensions (internal issue 1796).
* Clarify requirements for external memory in NOTEs for
sname:VkExternalMemoryBufferCreateInfo, and valid usage statements for
flink:vkBindBufferMemory, slink:VkBindBufferMemoryInfo,
flink:vkBindImageMemory, and slink:VkBindImageMemoryInfo (internal merge
request 3301).
* Make extension version numbers in `vk.xml` and extension appendices
consistent. In a few cases, we could not recover history at this
granularity, and left the summary of a version's change undefined
(internal merge request 3323).
* Fix invocation of `CodeInlineMacro` in the Ruby extension backing the
`code:` macro, which was delegating to the wrong base class (internal
merge request 3331).
* Modify `reg.py` to do a better job of recognizing equivalent <enum>
definitions.
* Add a `sortorder` attribute to XML feature and extension tags.
New Extensions
* `<<VK_AMD_device_coherent_memory>>`
* Update release number to 120.
Github Issues:
* Add slink:VkAccelerationStructureTypeNV explicitly to extension XML for
`<<VK_NV_ray_tracing>>` (public issue 848).
* Add missing valid usage statements for feature flags in
slink:VkCommandBufferInheritanceInfo (public pull request 1017).
Internal Issues:
* Clarify behavior of non-premultiplied destination colors for
`<<VK_EXT_blend_operation_advanced>>` prior to the definition of
slink:VkBlendOverlapEXT (internal issue 1766).
* Fix the confusing phrasing "`no other queue must: be (doing something)`"
for flink:vkQueuePresentKHR, flink:vkQueueSubmit, and
flink:vkQueueBindSparse (internal issue 1774).
* Add `<<VK_EXT_validation_features>>` flag to enable best practices
checks, which will soon be available in the validation layer (internal
issue 1779).
* Specify allowed characters for VUID tag name components in the style
guide (internal issue 1788).
* Update links to SPIR-V extension specifications, and parameterize their
markup in case the URLs change in the future (internal issue 1797).
* Fix an off-by-one error in the valid usage statement for
slink:VkPipelineExecutableInfoKHR (internal merge request 3303).
* Clean up markup indentation not matching the style guide (internal merge
request 3314).
* Minor script updates to allow refpage aliases, generate a dynamic TOC
for refpages, generate Apache rewrite rules for aliases, open external
links from refpages in a new window, and synchronize with the OpenCL
scripts. This will shortly enable a paned navigation setup for refpages,
similar to the OpenCL 2.2 refpages (internal merge request 3322).
* Script updates to add tests to the checker, refactor and reformat code,
generate better text for some valid usage statements, use more Pythonic
idioms, and synchronize with the OpenXR scripts (internal merge request
3239).
* Script updates and minor fixes in spec language to not raise checker
errors for refpage markup of pages not existing in the API, such as
VKAPI_NO_STDINT_H. Remove corresponding suppression of some
check_spec_links.py tests from .gitlab-ci.yml and 'allchecks' target
(internal merge request 3315).
* Update release number to 106.
Public Issues:
* Add searchbox and generate search index for the chunked HTML target.
Note that doing this requires several new toolchain components to build
the `chunked` target (public issue 578 / internal issue 1352).
* Remove descriptions of flink:vkCreateSampler sampler constraints which
were repeated in the valid usage statements (public pull request 648).
* Fix sense of conditional around a valid usage statement in the
<<copies>> chapter (public issue 942).
Internal Issues:
* Add missing pname:extent.width and pname:extent.height valid usage
statements for flink:vkCmdClearAttachments (internal issue 1583).
* Fix some inconsistencies in structures and corresponding pname:sType
enumerant names by renaming
sname:VkPhysicalDeviceShaderDrawParameterFeatures ->
slink:slink:VkPhysicalDeviceShaderDrawParametersFeatures;
sname:VkPhysicalDeviceVariablePointerFeatures ->
slink:VkPhysicalDeviceVariablePointerFeatures;
sname:VkPhysicalDeviceVariablePointerFeaturesKHR ->
slink:VkPhysicalDeviceVariablePointerFeaturesKHR;
sname:VkPhysicalDeviceBufferAddressFeaturesEXT ->
slink:VkPhysicalDeviceBufferDeviceAddressFeaturesEXT;
etext:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_DRAW_PARAMETER_FEATURES
->
ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_DRAW_PARAMETERS_FEATURES;
etext:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTER_FEATURES ->
ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTERS_FEATURES;
etext:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTER_FEATURES_KHR ->
ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTERS_FEATURES_KHR;
and etext:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_ADDRESS_FEATURES_EXT
->
ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_DEVICE_ADDRESS_FEATURES_EXT.
The old names are still available as aliases for backwards
compatibility. This change required introducing valid XML markup which
externally written XML processing scripts may need to be modified to
accomodate, to support multiple aliases of a single command or token
name (internal issue 1592).
* Add slink:VkDevice as the first parameter to flink:vkSetLocalDimmingAMD
(internal issue 1618).
* Improve CI header compilation tests to test all Vulkan platform
includes, using fake platform headers where needed, and change the
`allchecks` Makefile target to use the more comprehensive
`check_spec_links.py` script instead of the retired `checkinc` and
`checklinks` targets.
* Move descriptions of the ASTC compressed texture decode mode from the
<<appendix-compressedtex-astc,appendix>> to the recently updated
external Khronos Data Format Specification.
* Fix minor markup and spelling issues in the `VK_NV_ray_tracing`
extension.
* Update release number to 98.
Public Issues:
* Fix missing markup in flink:vkDestroyPipelineLayout valid usage
statement (pull request 882).
* Add missing contributors for `<<VK_EXT_buffer_device_address>>` (public
pull request 891).
Internal Issues:
* Detect nested bullet points in valid usage blocks and warn about them
during VUID assignment (internal issue 1382).
* Update the style guide to document the process for reserving new bits in
bitmask types (internal issue 1411).
* Clarify for slink:VkApplicationInfo::pname:apiVersion and in the
<<fundamentals-validusage-versions, Valid Usage for Newer Core
Versions>> section when it is valid for an application to use a certain
version of Vulkan API functionality (for an instance and for a
device/physical device); and when the validation layers must generate an
error (internal issue 1412).
* Add optional <<memory-model-availability-visibility, transitive
availability/visibility operations to the memory model, including a new
pname:vulkanMemoryModelAvailabilityVisibilityChains feature for
slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR (internal issue
1460).
* Add the code:StorageBuffer storage class to those in the
<<interfaces-resources-descset, Descriptor Set Interface>> (internal
issue 1480).
* Add missing `returnedonly` tags for a number of returned extension
structures that can be passed in pname:pNext chains (internal issue
1515).
* Clean up and rearrange some spec language for
slink:VkRenderPassCreateInfo and slink:VkAttachmentReference.txt
(internal issue 1522).
* Correctly round the code:OpVectorTimesScalar and
code:OpMatrixTimesScalar SPIR-V operations in the <<Precision of core
SPIR-V Instructions>> table (internal merge request 2996).
* Work around cases in flink:vkCmdBeginTransformFeedbackEXT,
flink:vkCmdEndTransformFeedbackEXT, and
slink:VkPipelineCoverageModulationStateCreateInfoNV where an array
parameter is `optional` but the length is not in `vk.xml`. This is an
interim fix using `noautovalidity` + handcoded VU replacing those that
should be autogenerated (internal issue 2944 and
https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/480).
* Remove redundant capability validation of the code:float16 and code:int8
SPIR-V capabilities from the <<spirvenv-capabilities, Capabilities>>
section, since they are already covered in the preceding table.
* Update check_spec_links script, including validation for reference page
open blocks. Fix errors identified by the script.
* Update release number to 97.
Public Issues:
* Add a special case to the <<renderpass-compatibility, Render Pass
Compatibility>> rules allowing single-subpass renderpasses to be
compatible even if they have different resolve attachment references
(public issue 835).
* Fix the miss shader binding table record address rule in the
<<shader-binding-table-indexing-rules, Miss Shaders>> section to index
by code:missIndex, not code:sbtOffset (public issue 875).
Internal Issues:
* Add a missing anchor to the elink:VkSamplerCreateFlagBits language
(internal issue 1483).
* Add missing implicit valid usage include for slink:VkHdrMetadataEXT and
corresponding `noautovalidity` attributes in `vk.xml` for the
externally-defined metadata properties (internal issue 1514).
* Remove restrictions on the `mask` parameter of SPIR-V's
code:OpGroupNonUniformXor in the <<spirvenv-module-validation,
Validation Rules within a Module>> appendix (internal merge request
2971).
* Restore `noautovalidity` attribute for
slink:VkPipelineViewportWScalingStateCreateInfoNV::pname:pViewportWScalings
in `vk.xml` (internal merge request 2975).
* Update copyright dates on Khronos-copyrighted files to 2019 (internal
merge request 2980).
New Extensions:
* `VK_KHR_depth_stencil_resolve`
* `VK_EXT_buffer_device_address`
* `VK_EXT_memory_budget`
* `VK_EXT_memory_priority`
* `VK_EXT_validation_features`
