* Update release number to 122.
Internal Issues:
* Add style guide language on not using standalone `+` signs (internal
issue 736); not using leading whitespace for markup (internal issue
747); and on keeping descriptions of a single API in a contiguous block
of markup (internal issue 949), and apply them to the specification.
* Add a glossary definition of "`constant integral expression`", pointing
to the SPIR-V "`constant instruction`" definition (internal issue 1225).
* Many minor edits to improve writing style consistency and capture
additional style guidelines (internal issue 1553).
* Clarify that <<fragops-depth-write, depth writes are not performed>> if
there is no depth framebuffer attachment (internal issue 1771).
* Allow implementations to use rectangular line style of interpolation for
<<primsrast-lines-bresenham, wide Bresenham lines>>, though replicating
attributes is still preferred. Clarify that code:FragCoord is not
replicated (internal issue 1772).
* Resolve a contradiction in valid usage statements for
slink:VkImageCreateInfo and slink:VkImageStencilUsageCreateInfoEXT
(internal issue 1773).
* Add style guide discussion of markup for indented equations, and use
markup workaround for asciidoctor 2 compatibility (internal issue 1793).
* Deprecate the `<<VK_EXT_validation_flags>>` extension in `vk.xml` and
the extension appendix (internal issue 1801).
* Add a new checker script `scripts/xml_consistency.py`. This is not
currently run as part of internal CI (internal merge request 3285).
* Correct "`an`" -> "`a`" prepositions where needed (internal merge
request 3334).
* Clarify that the <<features-uniformBufferStandardLayout,
pname:uniformBufferStandardLayout>> feature is only required when the
extension defining it is supported (internal merge request 3341).
* Bring scripts into closer sync with OpenXR, mainly through conversion of
comments to docstrings where appropriate, and add gen-scripts-docs.sh
(internal merge request 3324).
* Correct pname:maxDrawMeshTasksCount to 2^16^-1 in the <<limits-required,
Required Limits>> table (internal merge requests 3361).
New Extensions
* `<<VK_IMG_format_pvrtc>>` (public issue 512).

Applications may wish to update a fixed set of descriptors in a large number
|
|
of descriptors sets very frequently, i.e. during initializaton phase or if
|
|
it is required to rebuild descriptor sets for each frame.
|
|
For those cases it is also not unlikely that all information required to
|
|
update a single descriptor set is stored in a single struct.
|
|
This extension provides a way to update a fixed set of descriptors in a
|
|
single slink:VkDescriptorSet with a pointer to a user defined data structure
|
|
describing the new descriptors.
|
|
|
|
|
|
=== New Object Types
|
|
|
|
* sname:VkDescriptorUpdateTemplateKHR
|
|
|
|
=== New Enum Constants
|
|
|
|
Extending elink:VkStructureType:
|
|
|
|
** ename:VK_STRUCTURE_TYPE_DESCRIPTOR_UPDATE_TEMPLATE_CREATE_INFO_KHR
|
|
|
|
=== New Enums
|
|
|
|
* tlink:VkDescriptorUpdateTemplateCreateFlagsKHR
|
|
* elink:VkDescriptorUpdateTemplateTypeKHR
|
|
|
|
=== New Structures
|
|
|
|
* slink:VkDescriptorUpdateTemplateEntryKHR
|
|
* slink:VkDescriptorUpdateTemplateCreateInfoKHR
|
|
|
|
=== New Functions
|
|
|
|
* flink:vkCreateDescriptorUpdateTemplateKHR
|
|
* flink:vkDestroyDescriptorUpdateTemplateKHR
|
|
* flink:vkUpdateDescriptorSetWithTemplateKHR
|
|
ifdef::VK_KHR_push_descriptor[]
|
|
* flink:vkCmdPushDescriptorSetWithTemplateKHR
|
|
endif::VK_KHR_push_descriptor[]
|
|
|
|
=== Promotion to Vulkan 1.1
|
|
|
|
ifdef::VK_KHR_push_descriptor[]
|
|
flink:vkCmdPushDescriptorSetWithTemplateKHR is included as an interaction
|
|
with `<<VK_KHR_push_descriptor>>`.
|
|
If Vulkan 1.1 and VK_KHR_push_descriptor are supported, this is included by
|
|
`<<VK_KHR_push_descriptor>>`.
|
|
endif::VK_KHR_push_descriptor[]
|
|
|
|
The base functionality in this extension is included in core Vulkan 1.1,
|
|
with the KHR suffix omitted.
|
|
The original type, enum and command names are still available as aliases of
|
|
the core functionality.
