* Bump API patch number and header version number to 53 for this update.
Github Issues:
Internal Issues:
* Clarify mappings of coordinates for mutable, compatible image views in
slink:VkImageViewCreateInfo (internal issue 815).
* Make ename:VK_BIND_SFR_BIT require a logical device with multiple
physical devices, so that standard sparse image block dimensions are
only required on systems that support multi-GPU (internal issue 835).
* Convert all files from use of // refBegin .. // refEnd comments to
delimit ref pages, to use of open blocks, and update style guide
accordingly (internal issue 839).
* Add valid usage for slink:VkWriteDescriptorSet when performing updates
to a ename:VK_STORAGE_IMAGE descriptor with layout
ename:VK_IMAGE_LAYOUT_GENERAL.
* Add a hack to the validity generator script to support an odd
interaction between flink:vkCmdFillBuffer and an extension (internal
issue 853).
* Remove redundant text describing slink:VkBufferCreateInfo::pname:usage,
which was already covered by implicit valid usage (internal issue 854).
* Update implicit validity generator script to properly handle the
pname:sType and pname:pNext members of "returnedonly" structures
(internal issue 874).
* Note that slink:VkApplicationInfo::pname:pApplicationName &
slink:VkApplicationInfo::pname:pEngineName are optional, and add missing
implicit valid usage statements for flink:vkDestroyInstance.
* Added missing valid usage for flink:vkCmdWriteTimestamp to require a
timestamp query pool.
* Simplify and/or split "`non-atomic`" valid usage statements.
New Extensions:
* `VK_AMD_gpu_shader_int16`
* `VK_EXT_blend_operation_advanced`
* `VK_EXT_sampler_filter_minmax`
* `VK_NV_framebuffer_mixed_samples`
-----------------------------------------------------
Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release
combines both change sets.
-----------------------------------------------------
Change log for June 13, 2017 Vulkan 1.0.52 spec update:
* Bump API patch number and header version number to 52 for this update.
Github Issues:
Internal Issues:
* Clarify behavior when non-coherent memory has
<<memory-device-unmap-does-not-flush, not been flushed before being
unmapped>> (internal issue 819).
* Fix description of code:WorkgroupSize builtin to note it decorates an
object, not a variable (internal issue 836).
* Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style
equations are rendered properly (internal issue 845).
* Add language to the "`Extension Handles, Objects, Enums, and Typedefs`"
section of the Procedures and Conventions document stating that any new
handle type requires a corresponding entry in the elink:VkObjectType
enumerated type (internal issue 856).
* Update style guide to use slink macro for Vulkan handle type names, and
define narrow conditions under which to use the *name and *text macros
instead of *link (internal issue 886).
* Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>>
extension on VK_KHX_device_group_creation to +vk.xml+ and the extension
appendix.
* Change the copyright on Vulkan specification asciidoc *source* files to
CC-BY 4.0, and update the proprietary Khronos copyright applied to the
generated *output* formats (internal issue 327). This enables broader
re-use and modification of the Vulkan specification sources, while not
affecting the Reciprocal IP License between Vulkan Adopters and Working
Group Members.
New Extensions:
* `VK_NV_fill_rectangle`
* `VK_NV_fragment_coverage_to_color`

== 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.

chromaticity coordinates

chromaticity coordinates

nits

|
* pname:maxContentLightLevel is content's maximum luminance in nits
|
|
* pname:maxFrameAverageLightLevel is the maximum frame average light level

in nits
