Change log for November 1, 2020 Vulkan 1.2.159 spec update:

  * Update release number to 159 for this update.

Github Issues:

  * Clarify handle uniqueness with private data in the
    <<fundamentals-objectmodel-overview, Object Model>> section (public
    issue 1349).
  * Make ename:VK_PERFORMANCE_COUNTER_DESCRIPTION_PERFORMANCE_IMPACTING_KHR
    an alias of
    ename:VK_PERFORMANCE_COUNTER_DESCRIPTION_PERFORMANCE_IMPACTING_BIT_KHR
    and ename:VK_PERFORMANCE_COUNTER_DESCRIPTION_CONCURRENTLY_IMPACTED_KHR
    an alias of
    ename:VK_PERFORMANCE_COUNTER_DESCRIPTION_CONCURRENTLY_IMPACTED_BIT_KHR,
    for backwards compatibility while complying with naming conventions
    (public issue 1367).
  * Make ename:VK_SURFACE_COUNTER_VBLANK_EXT an alias of
    ename:VK_SURFACE_COUNTER_VBLANK_BIT_EXT for backwards compatibility
    while complying with naming conventions (public issue 1368).
  * Add a note to the <<memory-model-synchronizes-with, Synchronizes-With>>
    section that fragment shader interlock instructions don't perform
    implicit availability or visibility operations (public issue 1383).

Internal Issues:

  * Dynamically generate SPIR-V <<spirvenv-capabilities-table,
    Capabilities>> and <<spirvenv-extensions-table, Extensions>> tables from
    new tags in `vk.xml`, exposing this information for other projects
    downstream (internal issue 2156).
  * Clarify when a <<renderpass-feedbackloop, feedback loop>> creates a data
    race (internal issue 2296).
  * Remove un-needed `noautovalidity` attributes on pname:pNext structure
    members, including a few cases where they were actually suppressing
    appropriate autogenerated validity statements (internal issue 2335;
    similar purpose to closed public PR 1339).
  * Clarify treatment of most-negative signed normalized fixed-point values
    in the <<fundamentals-fixedfpconv, Conversion from Normalized
    Fixed-Point to Floating-Point>> section (internal issue 2367).
  * Clarify that enabling an extension cannot change existing implementation
    behavior in the introduction to the <<extendingvulkan-extensions,
    Extensions>> chapter (internal issue 2375).
  * Add missing valid usage statement to flink:vkCreatePrivateDataSlotEXT
    (internal issue 2379).
  * Fix a misplaced asciidoctor `endif::` for flink:vkCreateSwapchainKHR
    (internal merge request 4177).
  * Add missing pname:aspectMask valid usage statement to
    slink:VkSubpassDescription2, matching
    slink:VkInputAttachmentAspectReference (internal merge request 4177).
  * Clarify <<interfaces, SPIR-V rules on decorations>> (internal
    spirv/SPIR-V issue 444).
  * Add missing `<<VK_VERSION_1_2>>` to all
    `<<VK_EXT_separate_stencil_usage>>` conditional markup (internal
    vulkansc/vulkansc issue 58).

New Extensions:

  * `<<VK_QCOM_rotated_copy_commands>>` (internal merge request 4132).

    flink:vkCmdSetScissor, flink:vkCmdSetExclusiveScissorNV,
    flink:vkCmdSetViewportShadingRatePaletteNV, and flink:vkCmdSetViewport
    (internal merge request 4200).

New Extensions:

  * `<<VK_NV_fragment_shading_rate_enums>>`

source: https://github.com/KhronosGroup/Vulkan-Docs/commit/f90136facacd25f016e523064f03713bdfe1b22d

New extension:
- VK_NV_fragment_shading_rate_enums
Quote
This extension builds on the fragment shading rate functionality provided by
the VK_KHR_fragment_shading_rate extension, adding support for "supersample"
fragment shading rates that trigger multiple fragment shader invocations per
pixel as well as a "no invocations" shading rate that discards any portions
of a primitive that would use that shading rate.

Vulkan API specifications 1.2.161 released
« Reply #122 on: November 23, 2020, 12:03:34 PM »
Quote
Change log for November 16, 2020 Vulkan 1.2.161 spec update:

  * Update release number to 161 for this update.

Github Issues:

  * Add some missing types to the table of handle type <->
    etext:VK_OBJECT_TYPE_* enums in the debugging chapter (in response to a
    comment on public issue 1379).

Internal Issues:

  * Move copyright statement into its own "`Preamble`" chapter to simplify
    preprocessing for chunked HTML target and make PDF / single-page HTML
    consistent with the chunked output (internal issue 2384).
  * Clarify that slink:VkExternalMemoryBufferCreateInfo::pname:handleTypes
    and slink:VkExternalMemoryImageCreateInfo::pname:handleTypes can be
    zero, and fix missing `optional` attribute in `vk.xml` for the latter
    case (internal issue 2388).
  * Make `specialuse` attributes in source markup expand properly in
    extension refpages (internal issue 2412).

    slink:VkRenderPassMultiviewCreateInfo::pname:pViewMask in the
    slink:VkRenderPassCreateInfo pname:pNext chain, and for
    slink:VkRenderPassCreateInfo2::pname:viewMask. These statements cannot
    ever be violated given that view masks cannot exceed index 31 and
    pname:maxFramebufferLayers exceeds this value (internal merge request
    4204).
  * Only allow forward pointers for physical storage buffers in the
    <<spirvenv-module-validation>> section (internal merge request 4206).
  * Fix a variety of minor valid usage statement issues with the
    `<<VK_KHR_fragment_shading_rate>>` extension (internal merge request
    4207).

Vulkan API specifications 1.2.162 released
« Reply #123 on: November 23, 2020, 12:09:42 PM »

Change log for November 23, 2020 Vulkan 1.2.162 spec update:

  * Update release number to 162 for this update.

Github Issues:

  * Mark pname:pNext pointers as `optional="true"` in `vk.xml` (public pull

  ** `<<VK_KHR_ray_query>>`
  ** `<<VK_KHR_pipeline_library>>`
  ** `<<VK_KHR_deferred_host_operations>>`

Source: https://github.com/KhronosGroup/Vulkan-Docs/commit/c5d94a31766e91607473ca0049a293e3f632c6ff

New extensions

- VK_KHR_acceleration_structure
Quote
In order to be efficient, rendering techniques such as ray tracing need a
quick way to identify which primitives may be intersected by a ray
traversing the geometries.
Acceleration structures are the most common way to represent the geometry
spatially sorted, in order to quickly identify such potential intersections.


- VK_KHR_ray_tracing_pipeline
Quote
Rasterization has been the dominant method to produce interactive graphics,
but increasing performance of graphics hardware has made ray tracing a
viable option for interactive rendering.
Being able to integrate ray tracing with traditional rasterization makes it
easier for applications to incrementally add ray traced effects to existing
applications or to do hybrid approaches with rasterization for primary
visibility and ray tracing for secondary queries.

To enable ray tracing, this extension adds a few different categories of new
functionality:

  * A new ray tracing pipeline type with new shader domains: ray generation,
    intersection, any-hit, closest hit, miss, and callable
  * A shader binding indirection table to link shader groups with
    acceleration structure items
  * Trace ray commands which initiates the ray pipeline traversal and
    invocation of the various new shader domains depending on which
    traversal conditions are met


- VK_KHR_ray_query
Quote
Rasterization has been the dominant method to produce interactive graphics,
but increasing performance of graphics hardware has made ray tracing a
viable option for interactive rendering.
Being able to integrate ray tracing with traditional rasterization makes it
easier for applications to incrementally add ray traced effects to existing
applications or to do hybrid approaches with rasterization for primary
visibility and ray tracing for secondary queries.

Ray queries are available to all shader types, including graphics, compute
and ray tracing pipelines.
Ray queries are not able to launch additional shaders, instead returning
traversal results to the calling shader.

- VK_KHR_pipeline_library
Quote
A pipeline library is a special pipeline that cannot be bound, instead it
defines a set of shaders and shader groups which can be linked into other
pipelines.
This extension defines the infrastructure for pipeline libraries, but does
not specify the creation or usage of pipeline libraries.
This is left to additional dependent extensions.


- VK_KHR_deferred_host_operations
Quote
The VK_KHR_deferred_host_operations extension defines the infrastructure
and usage patterns for deferrable commands, but does not specify any
commands as deferrable.

source: https://github.com/KhronosGroup/Vulkan-Docs/commit/8f718b4194ed1e0a572d37072e5558dd9ceabcb0

New Extensions

- VK_NV_acquire_winrt_display
Quote
This extension allows an application to take exclusive control of a display
on Windows 10 provided that the display is not already controlled by a
compositor.
When control is acquired the application has exclusive access to the display
until control is released or the application terminates.
An application's attempt to acquire is denied if a different application has
already acquired the display.

- VK_VALVE_mutable_descriptor_type
Quote
This extension allows applications to reduce descriptor memory footprint by
allowing a descriptor to be able to mutate to a given list of descriptor
types depending on which descriptor types are written into, or copied into a
descriptor set.
