This extension adds support for several new integer instructions in SPIR-V
|
|
|
|
|
for use in graphics shaders.
|
|
|
|
|
Many of these instructions have pre-existing counterparts in the Kernel
|
|
|
|
|
environment.

Change log for August 17, 2019 Vulkan 1.1.120 spec update:
* 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).

Change log for July 14, 2019 Vulkan 1.1.115 spec update:
* Update release number to 115.
GitHub issues:
* Add valid usage statements to slink:VkWriteDescriptorSet and
slink:VkCopyDescriptorSet specifying that updating immutable descriptors
with ename:VK_DESCRIPTOR_TYPE_SAMPLER is invalid, and that updating
ename:VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER ignores the update's
samplers (public issue 985).
* Document that the `manhtmlpages` target requires building with all
extensions enabled, in `BUILD.adoc` (public issue 992).
* Fix reference to the wrong subpass in valid usage statement for
slink:VkRenderPassCreateInfo (public pull request 994).
Internal Issues:
* Rename slink:VkPhysicalDeviceShaderIntegerFunctions2INTEL and
ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_INTEGER_FUNCTIONS2_FEATURES_INTEL
for consistency with global naming conventions, and to help code
generation in other projects (internal issue 1685).
* Update valid usage statements for image code:Offset / code:ConstOffset
usage in the <<textures-gather, Texel Gathering>> and
<<spirvenv-module-validation, Validation Rules within a Module>>
sections, and for the <<limits-minTexelGatherOffset>> and
<<limits-maxTexelGatherOffset>> limits (internal issue 1723).
* Require code:code:OpGroupNonUniformBroadcast to take a constant `Id`
operand in the <<spirvenv-module-validation, Validation Rules within a
Module>> sections (internal issue 1726).
* Note that the swapchain specified in slink:VkImageSwapchainCreateInfoKHR
when creating an image must match the one specified in
slink:VkBindImageMemorySwapchainInfoKHR when binding memory to the image
(internal issue 1729).
* Remove stext:KHR suffix from some structure cross-references that were
promoted to Vulkan 1.1 (internal issue 1730).
* Fix structure name in `structextends` attribute for
slink:VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT in `vk.xml`
(internal issue 1740).
* Fix an error in the code:ClipColor() pseudocode for
<<VK_EXT_blend_operation_advanced>> (internal issue 1741).
* Add a row for
ename:VK_QUERY_TYPE_ACCELERATION_STRUCTURE_COMPACTED_SIZE_NV to the
description of elink:VkQueryType, and make a few related minor text
cleanups.
* Rename slink:VkPhysicalDeviceFloat16Int8FeaturesKHR to
slink:VkPhysicalDeviceShaderFloat16Int8FeaturesKHR for consistency,
retaining aliases of the old structure name and structure type enum for
backwards compatibility.
