* Bump API patch number and header version number to 61 for this update.
Github Issues:
* Provide alternate length attributes (altlen=) in the XML schema, for
those using length attributes to generate code instead of documentation
(public issue 555).
* Fix erroneous references to `latex:` being used for asciidoc math
markup, rather than `latexmath:` (public pull request 556).
* Add author ID to XML for Kazan software renderer (public pull request
557).
Internal Issues:
* Add the <<fundamentals-abi,Application Binary Interface>> section
describing platform ABI requirements and recommendations, add examples
of function and function pointer declarations to the
<<boilerplate-platform-specific-calling-conventions, Platform-Specific
Calling Conventions>> section, and remove related language that existed
elsewhere in the specification (internal issue 64).
* Describe where to document valid usage interactions of chained
structures in the style guide, and fix one case now appearing in
slink:VkBufferCreateInfo instead of the child
slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue
715).
* Add example to the style guide of describing enumerated types which are
empty when the spec is built without relevant extensions enabled, and
apply it to existing examples for
elink:VkDescriptorSetLayoutCreateFlagBits and
elink:VkSubpassDescriptionFlagBits (internal issue 864).
* Add a note to the <<fundamentals-validusage-enums, Valid Usage for
Enumerated Types>> section that the special values suffixed with
etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and
etext:_MAX_ENUM are not part of the API and should: not be used by
applications (internal issue 872).
* Added note to flink:vkCmdUpdateBuffers explaining the performance
penalty for copies done in this way, and why the upper copy limit is
what it is (internal issue 952).
* Update `VK_KHX_device_group` to split some functionality into the new
`VK_KHR_bind_memory2` extension, and rename that functionality (internal
issue 969).
* Remove *Status* fields from extension appendices, since they are by
definition published and complete by the time they reach the public
github repository (internal issue 973).
Other Issues:
* Update Data Format specification dependency to version 1.2 and change
references to DF sections accordingly.
* Update XML to make the pname:pAllocator parameter of
flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in
the `VK_EXT_display_control` extension as optional.
New Extensions:
* `VK_KHR_bind_memory2`
* `VK_KHR_image_format_list`
* `VK_KHR_maintenance2`
* `VK_KHR_sampler_ycbcr_conversion`

|
|
This extension adds support for the following SPIR-V extension in Vulkan:
|
|
|
|
* +SPV_NV_viewport_array2+
|
|
|
|
which allows a single primitive to be broadcast to multiple viewports and/or
|
|
multiple layers.
|
|
A new shader built-in output code:ViewportMaskNV is provided, which allows a
|
|
single primitive to be output to multiple viewports simultaneously.
|
|
Also, a new SPIR-V decoration is added to control whether the effective
|
|
viewport index is added into the variable decorated with the *Layer*
|
|
built-in decoration.
|
|
These capabilities allow a single primitive to be output to multiple layers
|
|
simultaneously.
|
|
|
|
This extension allows variables decorated with the code:Layer and
|
|
code:ViewportIndex built-ins to be exported from vertex or tessellation
|
|
shaders, using the code:ShaderViewportIndexLayerNV capability.
|
|
|
|
This extension adds a new code:ViewportMaskNV built-in decoration that is
|
|
available for output variables in vertex, tessellation evaluation, and
|
|
geometry shaders, and a new code:ViewportRelativeNV decoration that can be
|
|
added on variables decorated with code:Layer when using the
|
|
code:ShaderViewportMaskNV capability.
|
|
|
|
When using GLSL source-based shading languages, the code:gl_ViewportMask[]
|
|
built-in output variable and code:viewport_relative layout qualifier from
|
|
+GL_NV_viewport_array2+ map to the code:ViewportMaskNV and
|
|
code:ViewportRelativeNV decorations, respectively.
|
|
Behaviour is described in the +GL_NV_viewport_array2+ extension
|
|
specificiation.

[NOTE]
|
|
.Note
|
|
====
|
|
The code:ShaderViewportIndexLayerNV capability is equivalent to the
|
|
code:ShaderViewportIndexLayerEXT capability added by
|
|
<<VK_EXT_shader_viewport_index_layer,VK_EXT_shader_viewport_index_layer>>.
