* Update release number to 107.
Public Issues:
* Fix revision date for the `<<VK_AMD_gpu_shader_half_float>>` appendix
(public issue 617).
* Make <<synchronization-pipeline-barriers-subpass-self-dependencies,
subpass self-dependencies>> less restrictive (public issue 777).
* Fix the `<<VK_EXT_full_screen_exclusive>>` dependency on
`<<VK_KHR_win32_surface>>` in `vk.xml` (public pull request 849).
* Remove single-page (`apispec.html`) refpage sub-targets from the
Makefile `allman` target and the build instructions. The target is still
present in the Makefile, but we have not been actively maintaining the
single-page document and do not promise it will work. The full
Specification and the individual API reference pages are what we support
and publish at present (public issue 949).
Internal Issues:
* De-duplicate common valid usage statements shared by multiple commands
or structures by using asciidoctor includes and dynamically assigning
part of the valid usage ID based on which command or structure they're
being applied to (internal issue 779).
* Add reference pages for constructs not part of the formal API, such as
platform calling convention macros, and script changes supporting them
This required suppressing some check_spec_links warning classes in order
to pass CI, until a more sophisticated fix can be done (internal issue
888).
* Change math notation for the elink:VkPrimitiveTopology descriptions to
use short forms `v` and `p` instead of `vertex` and `primitive`,
increasing legibility (internal issue 1611).
* Rewrite generated file includes relative to a globally specified path,
fixing some issues with refpage generation (internal issue 1630).
* Update contributor list for `<<VK_EXT_calibrated_timestamps>>`.
* Fix use of pathlin in `scripts/generator.py` so the script will work on
Windows under Python 3.5 (internal merge request 3107).
* Add missing conditionals around the
<<descriptorsets-accelerationstructure, Acceleration Structure>>
section (internal merge request 3108).
* More script synchronization with OpenXR spec repository (internal merge
request 3109).
* Mark the `<<VK_AMD_gpu_shader_half_float>>` and
`<<VK_AMD_gpu_shader_int16>>` extensions as deprecated in `vk.xml` and
the corresponding extension appendices (internal merge request 3112).
New Extensions:
* `<<VK_EXT_headless_surface>>`

To query the basic capabilities of a surface, needed in order to create a
|
|
swapchain, call:
|
|
|
|
include::{generated}/api/protos/vkGetPhysicalDeviceSurfaceCapabilities2EXT.txt[]
|
|
|
|
* pname:physicalDevice is the physical device that will be associated with
|
|
the swapchain to be created, as described for
|
|
flink:vkCreateSwapchainKHR.
|
|
* pname:surface is the surface that will be associated with the swapchain.
|
|
* pname:pSurfaceCapabilities is a pointer to an instance of the
|
|
slink:VkSurfaceCapabilities2EXT structure in which the capabilities are
|
|
returned.
|
|
|
|
fname:vkGetPhysicalDeviceSurfaceCapabilities2EXT behaves similarly to
|
|
flink:vkGetPhysicalDeviceSurfaceCapabilitiesKHR, with the ability to return
|
|
extended information by adding extension structures to the pname:pNext chain
|
|
of its pname:pSurfaceCapabilities parameter.

The sname:VkSurfaceCapabilities2EXT structure is defined as:
|
|
|
|
include::{generated}/api/structs/VkSurfaceCapabilities2EXT.txt[]
|
|
|
|
All members of sname:VkSurfaceCapabilities2EXT are identical to the
|
|
corresponding members of slink:VkSurfaceCapabilitiesKHR where one exists.
|
|
The remaining members are:
|
|
|
|
* pname:sType is the type of this structure.
|
|
* pname:pNext is `NULL` or a pointer to an extension-specific structure.
|
|
* pname:supportedSurfaceCounters is a bitmask of
|
|
elink:VkSurfaceCounterFlagBitsEXT indicating the supported surface
|
|
counter types.

.Valid Usage

****
|
|
* [[VUID-VkSurfaceCapabilities2EXT-supportedSurfaceCounters-01246]]
|
|
pname:supportedSurfaceCounters must: not include
|
|
ename:VK_SURFACE_COUNTER_VBLANK_EXT unless the surface queried is a
|
|
<<wsi-display-surfaces,display surface>>.

Bits which can: be set in

supported surface counter types, are:

include::{generated}/api/enums/VkSurfaceCounterFlagBitsEXT.txt[]
|
|
|
|
* ename:VK_SURFACE_COUNTER_VBLANK_EXT specifies a counter incrementing
|
|
once every time a vertical blanking period occurs on the display
|
|
associated with the surface.
