* Update release number to 97.
Public Issues:
* Add a special case to the <<renderpass-compatibility, Render Pass
Compatibility>> rules allowing single-subpass renderpasses to be
compatible even if they have different resolve attachment references
(public issue 835).
* Fix the miss shader binding table record address rule in the
<<shader-binding-table-indexing-rules, Miss Shaders>> section to index
by code:missIndex, not code:sbtOffset (public issue 875).
Internal Issues:
* Add a missing anchor to the elink:VkSamplerCreateFlagBits language
(internal issue 1483).
* Add missing implicit valid usage include for slink:VkHdrMetadataEXT and
corresponding `noautovalidity` attributes in `vk.xml` for the
externally-defined metadata properties (internal issue 1514).
* Remove restrictions on the `mask` parameter of SPIR-V's
code:OpGroupNonUniformXor in the <<spirvenv-module-validation,
Validation Rules within a Module>> appendix (internal merge request
2971).
* Restore `noautovalidity` attribute for
slink:VkPipelineViewportWScalingStateCreateInfoNV::pname:pViewportWScalings
in `vk.xml` (internal merge request 2975).
* Update copyright dates on Khronos-copyrighted files to 2019 (internal
merge request 2980).
New Extensions:
* `VK_KHR_depth_stencil_resolve`
* `VK_EXT_buffer_device_address`
* `VK_EXT_memory_budget`
* `VK_EXT_memory_priority`
* `VK_EXT_validation_features`

|
This extension provides new entry points to query device surface
|
|
capabilities in a way that can be easily extended by other extensions,
|
|
without introducing any further entry points.
|
|
This extension can be considered the `<<VK_KHR_surface>>` equivalent of the
|
|
`<<VK_KHR_get_physical_device_properties2>>` extension.
|
|
|
|
=== New Object Types
|
|
|
|
None.
|
|
|
|
=== New Enum Constants
|
|
|
|
* Extending elink:VkStructureType:
|
|
** ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SURFACE_INFO_2_KHR
|
|
** ename:VK_STRUCTURE_TYPE_SURFACE_CAPABILITIES_2_KHR
|
|
** ename:VK_STRUCTURE_TYPE_SURFACE_FORMAT_2_KHR
|
|
|
|
=== New Enums
|
|
|
|
None.
|
|
|
|
=== New Structures
|
|
|
|
* slink:VkPhysicalDeviceSurfaceInfo2KHR
|
|
* slink:VkSurfaceCapabilities2KHR
|
|
* slink:VkSurfaceFormat2KHR
|
|
|
|
=== New Functions
|
|
|
|
* flink:vkGetPhysicalDeviceSurfaceCapabilities2KHR
|
|
* flink:vkGetPhysicalDeviceSurfaceFormats2KHR
|
|
|
|
=== Issues
|
|
|
|
1) What should this extension be named?
|
|
|
|
*RESOLVED*: `VK_KHR_get_surface_capabilities2`.
|
|
Other alternatives:
|
|
|
|
* `VK_KHR_surface2`
|
|
* One extension, combining a separate display-specific query extension.
|
|
|
|
2) Should additional WSI query functions be extended?
|
|
|
|
*RESOLVED*:
|
|
|
|
* flink:vkGetPhysicalDeviceSurfaceCapabilitiesKHR: Yes.
|
|
The need for this motivated the extension.
|
|
* flink:vkGetPhysicalDeviceSurfaceSupportKHR: No.
|
|
Currently only has boolean output.
|
|
Extensions should instead extend
|
|
flink:vkGetPhysicalDeviceSurfaceCapabilities2KHR.
|
|
* flink:vkGetPhysicalDeviceSurfaceFormatsKHR: Yes.
|
|
* flink:vkGetPhysicalDeviceSurfacePresentModesKHR: No.
|
|
Recent discussion concluded this introduced too much variability for
|
|
applications to deal with.
|
|
Extensions should instead extend
|
|
flink:vkGetPhysicalDeviceSurfaceCapabilities2KHR.
|
|
* flink:vkGetPhysicalDeviceXlibPresentationSupportKHR: Not in this
|
|
extension.
|
|
* flink:vkGetPhysicalDeviceXcbPresentationSupportKHR: Not in this
|
|
extension.
|
|
* flink:vkGetPhysicalDeviceWaylandPresentationSupportKHR: Not in this
|
|
extension.
|
|
* flink:vkGetPhysicalDeviceWin32PresentationSupportKHR: Not in this
|
|
extension.
