* 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>>`

== Hdr Metadata
|
|
|
|
To improve color reproduction of content it is useful to have information
|
|
that can be used to better reproduce the colors as seen on the mastering
|
|
display.
|
|
That information can be provided to an implementation by calling
|
|
fname:vkSetHdrMetadataEXT.
|
|
The metadata will be applied to the specified sname:VkSwapchainKHR objects
|
|
at the next fname:vkQueuePresentKHR call using that sname:VkSwapchainKHR
|
|
object.
|
|
The metadata will persist until a subsequent fname:vkSetHdrMetadataEXT
|
|
changes it.
|
|
The definitions below are from the associated SMPTE 2086, CTA 861.3 and CIE
|
|
15:2004 specifications.
|
|
|
|
The definition of fname:vkSetHdrMetadataEXT is:
|
|
|
|
[open,refpage='vkSetHdrMetadataEXT',desc='function to set Hdr metadata',type='protos']

|
* pname:device is the logical device where the swapchain(s) were created.
|
|
* pname:swapchainCount is the number of swapchains included in
|
|
pname:pSwapchains.
|
|
* pname:pSwapchains is a pointer to the array of pname:swapchainCount
|
|
sname:VkSwapchainKHR handles.
|
|
* pname:pMetadata is a pointer to the array of pname:swapchainCount
|
|
sname:VkHdrMetadataEXT structures.

Chromaticity coordinates x and y are as specified in CIE 15:2004
|
|
"`Calculation of chromaticity coordinates`" (Section 7.3) and are limited to
|
|
between 0 and 1 for real colors for the mastering display.
