[JeGX]

Change log for November 16, 2021 Vulkan 1.2.199 spec update:
  * Update release number to 199 for this update.

Github Issues:

  * Add upper bound for stext:AccelerationStructure geometry limits for
    slink:VkPhysicalDeviceRayTracingPropertiesNV and
    slink:VkPhysicalDeviceAccelerationStructurePropertiesKHR (public issue
    1670).
  * Trivial typos in proposal documents (public pull request 1682).
  * Add missing stage mask common valid usage statements to
    slink:VkSubmitInfo, slink:VkSubpassDependency, and
    slink:VkSubpassDependency2; remove unused common VU 4098; and add new
    stage mask VUs to flink:vkCmdBeginRenderPass,
    flink:vkCmdBeginRenderPass2, flink:vkCmdSetEvent, flink:vkCmdResetEvent,
    flink:vkCmdWaitEvents, and flink:vkCmdPipelineBarrier (public
    Vulkan-ValidationLayers pull request 3331).

Internal Issues:

  * Fix formatting of <<versions-1.0, Vulkan 1.0>> appendix section headers
    (internal issue 2921).
  * Fix location of bad conditional `endif::` in SPIR-V environment appendix
    VU 06271 (internal issue 2917).
  * Use etext:VK_VERSION_m_n instead of etext:VK_API_VERSION_m_n in
    `<spirvcapability>` and `<spirvextension>` XML tags for consistency with
    other version / extension reqiurements. Note that there is a possibility
    of this change affecting downstream consumers of the XML (internal issue
    2896).
  * Add refpage cross-reference from slink:VkSwapchainKHR to
    flink:vkQueuePresent (internal issue 2823).
  * Update apiext:VK_KHR_dynamic_rendering
    proposal document to use etext:STORE_OP_DONT_CARE
    (internal merge request 4924).
  * Fix most remaining dead links in the published specifications and
    refpages by adding missing API language for basetype:VkFlags64;
    stub reference pages for apiext:VK_NVX_binary_import; and
    tag refpage aliases for API constants which were promoted to core
    (internal merge request 4921).
  * Add description of elink:VkFormats in the new <formats>
    tag for `vk.xml`, and corresponding schema and script updates.
    (internal issues 1761, 2484, and 2811).

New Extensions:

  * apiext:VK_EXT_image_view_min_lod (internal merge request 4701).

source: https://github.com/KhronosGroup/Vulkan-Docs/commit/83c7507600618d8748bb911dfd8c3d9b4fabaca0

New extensions:
- VK_EXT_image_view_min_lod

This extension allows applications to clamp the minimum LOD value during
<<textures-image-level-selection,Image Level(s) Selection>> and
<<textures-integer-coordinate-operations,Integer Texel Coordinate
Operations>> with a given slink:VkImageView by
slink:VkImageViewMinLodCreateInfoEXT::pname:minLod.

This extension may be useful to restrict a slink:VkImageView to only mips
which have been uploaded, and the use of fractional pname:minLod can be
useful for smoothly introducing new mip levels when using linear mipmap
filtering.

Change log for November 23, 2021 Vulkan 1.2.200 spec update:
  * Update release number to 200 for this update.

Github Issues:

  * Refer to flink:vkCmdPipelineBarrier2KHR::pname:pDependencyInfo as a
    pointer, not an array (public issue 1456).
  * Fix spelling and add backwards-compatibility aliases for some
    elink:VkPipelinCreateFlagBits values (public issue 1676).
  * Fix typo in apiext:VK_INTEL_shader_integer_functions2 (public issue
    1696).
  * Replace usage of {depth, color} buffer with {depth, color} attachment
    (public pull request 1701).
  * Add restriction to the <<formats-mandatory-features-depth-stencil,
    manadatory format support table>> for depth/stencil formats preventing
    implementations from advertising those bits in
    slink:VkFormatProperties::pname:bufferFeatures (public
    Vulkan-ValidationLayers issue 3225).

Internal Issues:

  * Add an additional guarantee for buffer memory requirements in
    slink:VkMemoryRequirements as a minor update to the
    apiext:VK_KHR_maintenance4 extension (internal issue 2885).
  * Add a <<fundamentals-api-name-aliases, section to the fundamentals
    chapter>> describing typo aliases (internal issue 2897).
  * Determine extensions dependencies directly from `vk.xml` in the build
    scripts, rather than generating an auxiliary `extDependency.py` target
    (internal issue 2923).
  * Remove redundant SPIR-V `RuntimeSpirv` valid usage statements 04830,
    06271, 06374, and 06375 (internal merge requests 4827, 4830).
  * Suppress file-not-found `include::` errors for validusage target, using
    an IncludeProcessor extension, due to the way in which the validusage
    extension processes conditionals. Make all include paths absolute and
    require this in the style guide (internal merge request 4925).
  * Add missing `optional="true"` attribute to
    slink:VkCommandBufferInheritanceRenderingInfoKHR::pname:colorAttachmentCount
    (internal merge request 4935).
  * Remove references to apiext:VK_KHR_synchronization2 enums when that
    extension is not enabled in the specification being built (internal
    merge request 4937).
  * Minor wording changes for style guide compliance and consistency
    (internal merge request 4938).
  * Ignore etext:*_EXTENSION_NAME and etext:*_SPEC_VERSION aliases in
    `makemanaliases.py` script since there are no corresponding refpages for
    these meta-enums.

New Extensions:

  * apiext:VK_ARM_rasterization_order_attachment_access (internal merge
    request 3856).
  * apiext:VK_EXT_depth_clip_control (public issues 986 and 1054).

source: https://github.com/KhronosGroup/Vulkan-Docs/commit/9ed8caef1a0b5abe9778adb39feff435b2328f1b

New extensions:
- VK_ARM_rasterization_order_attachment_access

Renderpasses, and specifically
<<synchronization-pipeline-barriers-subpass-self-dependencies, subpass
self-dependencies>> enable much of the same functionality as the framebuffer
fetch and pixel local storage extensions did for OpenGL ES.
But certain techniques such as programmable blending are awkward or
impractical to implement with these alone, in part because a self-dependency
is required every time a fragment will read a value at a given sample
coordinate.

This extension extends the mechanism of input attachments to allow access to
framebuffer attachments when used as both input and color, or depth/stencil,
attachments from one fragment to the next, in rasterization order, without
explicit synchronization.

- VK_EXT_depth_clip_control

This extension allows the application to use the OpenGL depth range in NDC,
i.e. with depth in range [eq]#[-1, 1]#, as opposed to Vulkan's default of
[eq]#[0, 1]#.
The purpose of this extension is to allow efficient layering of OpenGL over
Vulkan, by avoiding emulation in the pre-rasterization shader stages.
This emulation, which effectively duplicates gl_Position but with a
different depth value, costs ALU and consumes shader output components that
the implementation may not have to spare to meet OpenGL minimum
requirements.

New Extensions:

  * apiext:VK_EXT_image_compression_control
  * apiext:VK_EXT_pipeline_properties
  * apiext:VK_EXT_subpass_merge_feedback
  * apiext:VK_KHR_ray_tracing_maintenance1

source: https://github.com/KhronosGroup/Vulkan-Docs/commit/71decb7f868d3891974eab139f03c7c6c87fea4d

New extensions:

- VK_EXT_image_compression_control

This extension enables fixed-rate image compression and adds the ability to
control when this kind of compression can be applied.
Many implementations support some form of framebuffer compression.
This is typically transparent to applications as lossless compression
schemes are used.
With fixed-rate compression, the compression is done at a defined bitrate.
Such compression algorithms generally produce results that are visually
lossless, but the results are typically not bit-exact when compared to a
non-compressed result.
The implementation may not be able to use the requested compression rate in
all cases.
This extension adds a query that can be used to determine the compression
scheme and rate that was applied to an image.

- VK_EXT_pipeline_properties

Vulkan SC requires offline compilation of pipelines.
In order to support this, the pipeline state is represented in a
https://github.com/KhronosGroup/VulkanSC-Docs/wiki/JSON-schema[JSON schema]
that is read by an offline tool for compilation.

One method of developing a Vulkan SC application is to author a Vulkan
application and use a layer to record and serialize the pipeline state and
shaders for offline compilation.
Each pipeline is represented by a separate JSON file, and can be identified
with a pname:pipelineIdentifier.

Once the pipelines have been compiled by the offline pipeline cache
compiler, the Vulkan SC application can then use this
pname:pipelineIdentifier for identifying the pipeline via Vulkan SC's
pname:VkPipelineIdentifierInfo structure.

This extension allows the Vulkan application to query the
pname:pipelineIdentifier associated with each pipeline so that the
application can store this with its pipeline metadata and the Vulkan SC
application will then use to map the same state to an entry in the Vulkan SC
pipeline cache.

It is expected that this extension will initially be implemented in the json
generation layer, although we can envision that there might be future uses
for it in native Vulkan drivers as well.

- VK_EXT_subpass_merge_feedback

This extension adds a mechanism to provide feedback to an application about
whether the subpasses specified on render pass creation are merged by the
implementation.
Additionally, it provides a control to enable or disable subpass merging in
the render pass.

- VK_KHR_ray_tracing_maintenance1

`VK_KHR_ray_tracing_maintenance1` adds a collection of minor ray tracing
features, none of which would warrant an entire extension of their own.

The new features are as follows:

  * Adds support for the `SPV_KHR_ray_cull_mask` SPIR-V extension in Vulkan.
    This extension provides access to built-in code:CullMaskKHR shader
    variable which contains the value of the code:OpTrace* `Cull Mask`
    parameter.
    This new shader variable is accessible in the intersection, any-hit,
    closest-hit and miss shader stages.
  * Adds support for a new pipeline stage and access mask built on top of
    `apiext:VK_KHR_synchronization2`:
  ** ename:VK_PIPELINE_STAGE_2_ACCELERATION_STRUCTURE_COPY_BIT_KHR to
     specify execution of <<acceleration-structure-copying, acceleration
     structure copy commands>>
  ** ename:VK_ACCESS_2_SHADER_BINDING_TABLE_READ_BIT_KHR to specify read
     access to a <<shader-binding-table, shader binding table>> in any
     shader pipeline stage
  * Adds two new acceleration structure query parameters:
  ** ename:VK_QUERY_TYPE_ACCELERATION_STRUCTURE_SIZE_KHR to query the
     acceleration structure size on the device timeline
  ** ename:VK_QUERY_TYPE_ACCELERATION_STRUCTURE_SERIALIZATION_BOTTOM_LEVEL_POINTERS_KHR
     to query the number of bottom level acceleration structure pointers for
     serialization
  * Adds an optional new indirect ray tracing dispatch command,
    flink:vkCmdTraceRaysIndirect2KHR, which sources the shader binding table
    parameters as well as the dispatch dimensions from the device.
    The <<features-rayTracingPipelineTraceRaysIndirect2,
    pname:rayTracingPipelineTraceRaysIndirect2>> feature indicates whether
    this functionality is supported.
