* 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.

This extension allows the application to query a 64-bit buffer device
|
|
address value for a buffer, which can be used to access the buffer memory
|
|
via the code:PhysicalStorageBufferEXT storage class in the
|
|
https://github.com/KhronosGroup/GLSL/blob/master/extensions/ext/GLSL_EXT_buffer_reference.txt[`GL_EXT_buffer_reference`]
|
|
GLSL extension and
|
|
{spirv}/EXT/SPV_EXT_physical_storage_buffer.html[`SPV_EXT_physical_storage_buffer`]
|
|
SPIR-V extension.
|
|
|
|
It also allows buffer device addresses to be provided by a trace replay
|
|
tool, so that it matches the address used when the trace was captured.

=== Issues
|
|
|
|
1) Where is VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_ADDRESS_FEATURES_EXT
|
|
and VkPhysicalDeviceBufferAddressFeaturesEXT?
|
|
|
|
*RESOLVED*: They were renamed as
|
|
ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_DEVICE_ADDRESS_FEATURES_EXT
|
|
and slink:VkPhysicalDeviceBufferDeviceAddressFeaturesEXT accordingly for
|
|
consistency.
|
|
Even though, the old names can still be found in the generated header files
|
|
for compatibility.
