* Update release number to 92.
Public Issues:
* Move and modify valid usage statements dealing with pname:aspectMask in
flink:vkCmdClearColorImage, flink:vkCmdClearDepthStencilImage, and
slink:VkClearAttachment, so they are in places where all necessary
information is available (public issue 529).
* Fix math markup in <<textures-texel-anisotropic-filtering, Texel
Anisotropic Filtering>> (public pull request 840).
* Fix misspellings (public pull request 845).
Internal Issues:
* Add installation instructions and a Makefile "`chunked`" target for
chunked HTML generation (internal issue 1352).
* Fix pipeline mesh diagram style; also fix a minor bug in the classic
pipeline diagram where vertex/index buffers wrongly fed into the vertex
shader (internal issue 1436).
* Make asciidoctor ERROR output raise an error, and don't suppress
executed command output from CI make invocation (internal issue 1454).
* Minor typo fixes and clarifications for `VK_NV_raytracing`.
* Cleanup extension-specific properties
** Remove duplicated documentation for pname:maxDiscardRectangles,
pname:pointClippingBehavior, and pname:maxVertexAttribDivisor (they
shouldn't be documented with the other members of
slink:VkPhysicalDeviceLimits at all).
** Remove duplicate anchor for pname:maxVertexAttribDivisor
** Consistently document stext:VkPhysicalDevice<Extension>PropertiesKHR
*** Always document pname:sType/pname:pNext (was inconsistent before)
*** Always mention chaining to slink:VkPhysicalDeviceProperties2 (and not
as slink:VkPhysicalDeviceProperties2KHR)
*** Always include Valid Usage statements last
* Update Makefile 'checklinks' target and associated scripts, and fix
markup problems identified by checkLinks.py, so that we can rely on the
checklinks script as part of Gitlab CI.

|
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.
