* 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`

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,VK_KHR_surface>>
|
|
equivalent of the <<VK_KHR_get_physical_device_properties2,
|
|
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, combined with VK_KHR_get_display_properties2
|
|
|
|
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:vkGetPhysicalDeviceMirPresentationSupportKHR: Not in this
|
|
extension.
|
|
* flink:vkGetPhysicalDeviceWin32PresentationSupportKHR: Not in this
|
|
extension.
