* Update release number to 97.
Public Issues:
* Add a special case to the <<renderpass-compatibility, Render Pass
Compatibility>> rules allowing single-subpass renderpasses to be
compatible even if they have different resolve attachment references
(public issue 835).
* Fix the miss shader binding table record address rule in the
<<shader-binding-table-indexing-rules, Miss Shaders>> section to index
by code:missIndex, not code:sbtOffset (public issue 875).
Internal Issues:
* Add a missing anchor to the elink:VkSamplerCreateFlagBits language
(internal issue 1483).
* Add missing implicit valid usage include for slink:VkHdrMetadataEXT and
corresponding `noautovalidity` attributes in `vk.xml` for the
externally-defined metadata properties (internal issue 1514).
* Remove restrictions on the `mask` parameter of SPIR-V's
code:OpGroupNonUniformXor in the <<spirvenv-module-validation,
Validation Rules within a Module>> appendix (internal merge request
2971).
* Restore `noautovalidity` attribute for
slink:VkPipelineViewportWScalingStateCreateInfoNV::pname:pViewportWScalings
in `vk.xml` (internal merge request 2975).
* Update copyright dates on Khronos-copyrighted files to 2019 (internal
merge request 2980).
New Extensions:
* `VK_KHR_depth_stencil_resolve`
* `VK_EXT_buffer_device_address`
* `VK_EXT_memory_budget`
* `VK_EXT_memory_priority`
* `VK_EXT_validation_features`

The `VK_KHR_xcb_surface` extension is an instance extension.
|
|
It provides a mechanism to create a slink:VkSurfaceKHR object (defined by
|
|
the `<<VK_KHR_surface>>` extension) that refers to an X11 code:Window, using
|
|
the XCB client-side library, as well as a query to determine support for
|
|
rendering via XCB.
|
|
|
|
=== New Object Types
|
|
|
|
None
|
|
|
|
=== New Enum Constants
|
|
|
|
* Extending elink:VkStructureType:
|
|
** ename:VK_STRUCTURE_TYPE_XCB_SURFACE_CREATE_INFO_KHR
|
|
|
|
=== New Enums
|
|
|
|
None
|
|
|
|
=== New Structures
|
|
|
|
* slink:VkXcbSurfaceCreateInfoKHR
|
|
|
|
=== New Functions
|
|
|
|
* flink:vkCreateXcbSurfaceKHR
|
|
* flink:vkGetPhysicalDeviceXcbPresentationSupportKHR
|
|
|
|
=== Issues
|
|
|
|
1) Does XCB need a way to query for compatibility between a particular
|
|
physical device and a specific screen? This would be a more general query
|
|
than flink:vkGetPhysicalDeviceSurfaceSupportKHR: If it returned
|
|
ename:VK_TRUE, then the physical device could be assumed to support
|
|
presentation to any window on that screen.
|
|
|
|
*RESOLVED*: Yes, this is needed for toolkits that want to create a
|
|
slink:VkDevice before creating a window.
|
|
To ensure the query is reliable, it must be made against a particular X
|
|
visual rather than the screen in general.
|
|
|
|
=== Version History
|
|
|
|
* Revision 1, 2015-09-23 (Jesse Hall)
|
|
- Initial draft, based on the previous contents of VK_EXT_KHR_swapchain
|
|
(later renamed VK_EXT_KHR_surface).
|
|
|
|
* Revision 2, 2015-10-02 (James Jones)
|
|
- Added presentation support query for an (xcb_connection_t*,
|
|
xcb_visualid_t) pair.
|
|
- Removed "root" parameter from CreateXcbSurfaceKHR(), as it is redundant
|
|
when a window on the same screen is specified as well.
|
|
- Adjusted wording of issue #1 and added agreed upon resolution.
|
|
|
|
* Revision 3, 2015-10-14 (Ian Elliott)
|
|
- Removed "root" parameter from CreateXcbSurfaceKHR() in one more place.
|
|
|
|
* Revision 4, 2015-10-26 (Ian Elliott)
|
|
- Renamed from VK_EXT_KHR_xcb_surface to VK_KHR_xcb_surface.
|
|
|
|
* Revision 5, 2015-10-23 (Daniel Rakos)
|
|
- Added allocation callbacks to vkCreateXcbSurfaceKHR.
|
|
|
|
* Revision 6, 2015-11-28 (Daniel Rakos)
|
|
- Updated the surface create function to take a pCreateInfo structure.
