* Update release number to 111.
Github Issues:
* Clean up flink:vkGetPhysicalDeviceSurfaceFormatsKHR and
flink:vkGetPhysicalDeviceSurfaceFormats2KHR to drop the
ename:VK_FORMAT_UNDEFINED case, require callers pass a supported
surface, and rearrange some validation-related language (public issue
207).
* Allow dynamic and nonuniform indexing of acceleration structures in the
<<interfaces-resources-descset, Descriptor Set Interface>> section
(public KhronosGroup/glslang issue 1766).
Internal Issues:
* Clarify when images require the use of YCbCr samplers for
slink:VkWriteDescriptorSet and slink:VkImageViewCreateInfo (internal
issue 1639).
* Remove the "`block`" language around <<features-robustBufferAccess,
vectorizing and robust buffer access>> (internal issue 1642).
* Allow code:OpTypeImageFormat == code:Unknown for input attachments in
the <<interfaces-resources-descset, Descriptor Set Interface>> section
(internal issue 1645).
* Fix asciidoctor conditionals around
ename:VK_ERROR_FULL_SCREEN_EXCLUSIVE_MODE_LOST_EXT in the
<<fundamentals-errorcodes>> section (internal issue 1679).
* Remove error codes from `vk.xml` for
flink:vkUninitializePerformanceApiINTEL, which has a `void` return type
(internal issue 1704).
* Various subgroup-related fixes in the <<spirvenv-capabilities,
Capabilities>>, <<shaders-subgroup-arithmetic, Arithmetic Subgroup
Operations>>, <<shaders-subgroup-clustered, Clustered Subgroup
Operations>>, and <<shaders-subgroup-partitioned, Partitioned Subgroup
Operations>> sections (internal merge request 3164).
* Fix asciidoctor markup affecting math rendering in the <<Precision of
core SPIR-V Instructions>> table (internal merge request 3166).
* Fix incorrect reference to flink:vkGetPhysicalDeviceFeatures2KHR in the
description of slink:VkPhysicalDeviceASTCDecodeFeaturesEXT (internal
merge request 3169).
* Fix a non-sentence in the introduction to the <<textures, Image
Operations Overview>> section (internal merge request 3184).
* Minor markup, grammar, and typo fixes for the
`<<NV_shader_sm_builtins>>` extension spec language (internal merge
request 3189).
* Clarify that 1D and 1D array format support is optional for cubic
filters, immediately following the <<formats-mandatory-features-astc,
Mandatory ASTC LDR format support>> table (internal merge request 3194).

=== Description
|
|
|
|
This extension provides the ability to determine device-specific properties
|
|
on NVIDIA GPUs.
|
|
It provides the number of streaming multiprocessors (SMs), the maximum
|
|
number of warps (subgroups) that can run on an SM, and shader builtins to
|
|
enable invocations to identify which SM and warp a shader invocation is
|
|
executing on.
|
|
|
|
This extension enables support for the SPIR-V code:ShaderSMBuiltinsNV
|
|
capability.
|
|
|
|
These properties and built-ins should: typically only be used for debugging
|
|
purposes.
|
|
|
|
|
|
=== New Object Types
|
|
|
|
None.
|
|
|
|
=== New Enum Constants
|
|
|
|
* Extending elink:VkStructureType:
|
|
** ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SM_BUILTINS_FEATURES_NV
|
|
** ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SM_BUILTINS_PROPERTIES_NV
|
|
|
|
=== New Enums
|
|
|
|
None.

|
=== New Functions
|
|
|
|
None.
|

=== Issues
|
|
. What should we call this extension?

|
|
RESOLVED: Using NV_shader_sm_builtins.
|
|
Other options considered included:
|
|
|
|
* NV_shader_smid - but SMID is really easy to typo/confuse as SIMD.
|
|
* NV_shader_sm_info - but *Info* is typically reserved for input
|
|
structures
