* 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`

This extension provides functionality to use a logical device that consists
|
|
of multiple physical devices, as created with the
|
|
`<<VK_KHR_device_group_creation>>` extension.
|
|
A device group can allocate memory across the subdevices, bind memory from
|
|
one subdevice to a resource on another subdevice, record command buffers
|
|
where some work executes on an arbitrary subset of the subdevices, and
|
|
potentially present a swapchain image from one or more subdevices.

=== Version History
|
|
|
|
* Revision 1, 2016-10-19 (Jeff Bolz)
|
|
- Internal revisions
|
|
* Revision 2, 2017-05-19 (Tobias Hector)
|
|
- Removed extended memory bind functions to VK_KHR_bind_memory2, added
|
|
dependency on that extension, and device-group-specific structs for
|
|
those functions.
|
|
* Revision 3, 2017-10-06 (Ian Elliott)
|
|
- Corrected Vulkan 1.1 interactions with the WSI extensions.
|
|
All Vulkan 1.1 WSI interactions are with the VK_KHR_swapchain
|
|
extension.
|
|
* Revision 4, 2017-10-10 (Jeff Bolz)
|
|
- Rename "SFR" bits and structure members to use the phrase "split
|
|
instance bind regions".
