Change log for March 3, 2019 Vulkan 1.1.102 spec update:
* Update release number to 102.
Public Issues:
* Simplify flink:vkGetImageMemoryRequirements constraint for
ename:VK_MEMORY_PROPERTY_LAZILY_ALLOCATED_BIT (public pull request 817).
* Fix typo in markup of the <<textures-texel-coordinate-systems-diagrams,
Texel Coordinate Systems, Corner Sampling>> image that was generating
complaints from chunked HTML output generation (public pull request
928).
Internal Issues:
* Split the old <<features, Features>> chapter into four chapters:
<<features, Features>>, <<limits, Limits>>, <<formats, Formats>>, and
<<capabilities, Capabilities>>, with minor edits to the introductory
paragraph of each chapter. Anchor names in these chapters were changed,
with corresponding effects to xrefs to these anchors elsewhere in spec
markup . The purpose is to make the chunked HTML spec output load faster
on what was previously a single, gigantic chapter (internal issue 1554).
* Add ename:VK_PIPELINE_STAGE_RAY_TRACING_SHADER_BIT_NV, to the supported
pipeline stages for ename:VK_ACCESS_UNIFORM_READ,
ename:VK_ACCESS_SHADER_READ, and ename:VK_ACCESS_SHADER_WRITE in the
<<synchronization-access-types-supported>> table.
* Correct legal name of Google, LLC in vk.xml \<tags> section and a
copyright statement.
* Clarify that Vulkan treats the Android
code:AHARDWAREBUFFER_FORMAT_R8G8B8X8_UNORM format as RGBA, and the
application is responsible for forcing the X/A component to be read as
1.0, in the <<memory-external-android-hardware-buffer-formats>> table.
* Clarify the vertex order of various primitive topologies, and define the
order of transform feedback vertex capture based on that. This involves
a lot of refactoring and cleanup in the <<drawing-primitive-topologies,
Primitive Topologies>>, <<geometry-input, Geometry Shader Input
Primitives>> sections, and <<vertexpostproc-transform-feedback Transform
Feedback>> sections, and numerous places in the <<tessellation>>
chapter,
New Extensions:
* `VK_EXT_metal_surface`
* `VK_EXT_ycbcr_image_arrays` (internal issue 1361).
* `VK_NVX_image_view_handle`

The `VK_EXT_metal_surface` extension is an instance extension.
|
|
|
|
|
It provides a mechanism to create a slink:VkSurfaceKHR object (defined by
|
|
|
|
|
the `<<VK_KHR_surface>>` extension) from dlink:CAMetalLayer, which is the
|
|
|
|
|
native rendering surface of Apple's Metal framework.
