* 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>>`

When the `VK_KHR_display_swapchain` extension is enabled, multiple
|
|
swapchains that share presentable images are created by calling:
|
|
|
|
include::{generated}/api/protos/vkCreateSharedSwapchainsKHR.txt[]
|
|
|
|
* pname:device is the device to create the swapchains for.
|
|
* pname:swapchainCount is the number of swapchains to create.
|
|
* pname:pCreateInfos is a pointer to an array of
|
|
slink:VkSwapchainCreateInfoKHR structures specifying the parameters of
|
|
the created swapchains.
|
|
* pname:pAllocator is the allocator used for host memory allocated for the
|
|
swapchain objects when there is no more specific allocator available
|
|
(see <<memory-allocation,Memory Allocation>>).
|
|
* pname:pSwapchains is a pointer to an array of slink:VkSwapchainKHR
|
|
handles in which the created swapchain objects will be returned.
|
|
|
|
fname:vkCreateSharedSwapchainsKHR is similar to flink:vkCreateSwapchainKHR,
|
|
except that it takes an array of slink:VkSwapchainCreateInfoKHR structures,
|
|
and returns an array of swapchain objects.
|
|
|
|
The swapchain creation parameters that affect the properties and number of
|
|
presentable images must: match between all the swapchains.
|
|
If the displays used by any of the swapchains do not use the same
|
|
presentable image layout or are incompatible in a way that prevents sharing
|
|
images, swapchain creation will fail with the result code
|
|
ename:VK_ERROR_INCOMPATIBLE_DISPLAY_KHR.
|
|
If any error occurs, no swapchains will be created.
|
|
Images presented to multiple swapchains must: be re-acquired from all of
|
|
them before transitioning away from ename:VK_IMAGE_LAYOUT_PRESENT_SRC_KHR.
|
|
After destroying one or more of the swapchains, the remaining swapchains and
|
|
the presentable images can: continue to be used.
