The Wine team is proud to announce that release 1.10 of vkd3d, the Direct3D to
Vulkan translation library, is now available.

This release contains improvements that are listed in the release notes below.
The main highlights are:

  - libvkd3d exposes various newer Direct3D 12 interfaces.
  - The HLSL compiler supports dynamic indexing of arrays.
  - libvkd3d-utils implements various helper functions for manipulating DXBC
    blobs.
  - Miscellaneous bug fixes.

The source is available from the following location:

  <https://dl.winehq.org/vkd3d/source/vkd3d-1.10.tar.xz>

The current source can also be pulled directly from the git repository:

  <https://gitlab.winehq.org/wine/vkd3d.git>

Vkd3d is available thanks to the work of multiple people. See the file AUTHORS
for the complete list.

# What's new in vkd3d 1.10

### libvkd3d

  - Creating pipeline state objects from pipeline state stream descriptions is
    implemented.
  - Depth-bounds testing is implemented.
  - When the VK\_KHR\_maintenance2 extension is available, libvkd3d will
    explicitly specify the usage flags of Vulkan image views. This is
    particularly useful on MoltenVK, where 2D-array views of 3D textures are
    subject to usage restrictions.
  - The D3D12\_FORMAT\_SUPPORT2\_UAV\_TYPED\_LOAD and/or
    D3D12\_FORMAT\_SUPPORT2\_UAV\_TYPED\_STORE feature flags are reported for
    UAV formats when the ‘shaderStorageImageReadWithoutFormat’ and/or
    ‘shaderStorageImageWriteWithoutFormat’ Vulkan device features are
    supported.
  - The ID3D12Device5 interface is supported.
  - The ID3D12GraphicsCommandList5 interface is supported.
  - The ID3D12Resource1 interface is supported.

### libvkd3d-shader

  - New features for the HLSL source type:
    - Support for the following intrinsic functions:
      - ceil()
      - degrees() and radians()
      - fwidth()
      - tan()
      - tex2Dlod(), tex2Dproj(), texCUBEproj(), and tex3Dproj()
    - Constant folding support for more expression types. In particular:
      - ternary operators and branches
      - reciprocal square roots
      - exponentials
      - logical ‘not’ on booleans
      - bitwise complements
      - left/right shifts
      - ceil(), floor(), frac(), and saturate()
    - Support for dynamic indexing of arrays.
    - Support for ‘break’ and ‘continue’ statements.
    - Support for ‘switch’ statements.
    - The ‘linear’, ‘centroid’, and ‘noperspective’ interpolation modifiers
      are supported.
    - The ‘RWTexture1DArray’ and ‘RWTexture2DArray’ unordered access view
      types are supported.
    - ‘\[loop\]’ attributes are accepted on loops.
    - u/U and l/L suffixes on integer constants.

  - Floating-point values are explicitly clamped to the upper and lower bounds
    of the target type by ‘ftoi’ and ‘ftou’ instructions when targeting
    SPIR-V. Similarly, NaNs are flushed to zero. Some hardware/drivers would
    already do this implicitly, but behaviour for such inputs is undefined as
    far as SPIR-V is concerned.

  - The VKD3D\_SHADER\_CONFIG environment variable can be used to modify the
    behaviour of libvkd3d-shader at run-time, analogous to the existing
    VKD3D\_CONFIG environment variable for libvkd3d. See the README for a list
    of supported options.

  - When scanning legacy Direct3D bytecode using vkd3d\_shader\_scan(),
    descriptor information for shader model 2 and 3 combined resource-sampler
    pairs is returned in the vkd3d\_shader\_scan\_descriptor\_info structure.
    Note that this information is not yet available for shader model 1
    sources, although this will likely be added in a future release.

  - The Direct3D shader assembly target supports the ‘rasteriser ordered view’
    flag (‘\_rov’) on unordered access view declarations.

  - New interfaces:
    - The VKD3D\_SHADER\_COMPILE\_OPTION\_BACKWARD\_COMPATIBILITY compile
      option can be used to specify backward compatibility options. The
      VKD3D\_SHADER\_COMPILE\_OPTION\_BACKCOMPAT\_MAP\_SEMANTIC\_NAMES flag is
      the only currently supported flag, and can be used to specify that
      shader model 1-3 semantic names should be mapped to their shader model
      4+ system value equivalents when compiling HLSL sources.
    - The VKD3D\_SHADER\_COMPILE\_OPTION\_FRAGMENT\_COORDINATE\_ORIGIN compile
      option can be used to specify the origin of fragment coordinates for
      SPIR-V targets. This is especially useful in OpenGL environments, where
      the origin may be different than in Direct3D or Vulkan environments.
    - The vkd3d\_shader\_scan\_combined\_resource\_sampler\_info structure
      extends the vkd3d\_shader\_compile\_info structure, and can be used to
      retrieve information about the combined resource-sampler pairs used by a
      shader. This is especially useful when compiling shaders for usage in
      environments without separate binding points for samplers and resources,
      like OpenGL.
    - vkd3d\_shader\_free\_scan\_combined\_resource\_sampler\_info() is used
      to free vkd3d\_shader\_scan\_combined\_resource\_sampler\_info
      structures.

### libvkd3d-utils

  - Passing the D3DCOMPILE\_ENABLE\_BACKWARDS\_COMPATIBILITY flag to
    D3DCompile() and D3DCompile2() will enable mapping shader model 1-3
    semantic names to their shader model 4+ system value equivalents.

  - New interfaces:
    - D3DGetBlobPart() is used to retrieve specific parts of DXBC blobs.
    - D3DGetDebugInfo() is used to retrieve debug information from DXBC blobs.
    - D3DGetInputAndOutputSignatureBlob() is used to retrieve input and output
      signatures from DXBC blobs.
    - D3DGetInputSignatureBlob() is used to retrieve input signatures from
      DXBC blobs.
    - D3DGetOutputSignatureBlob() is used to retrieve output signatures from
      DXBC blobs.
    - D3DStripShader() is used to remove specific parts from DXBC blobs.

### vkd3d-compiler

  - The ‘--fragment-coordinate-origin’ option can be used to specify the
    origin of fragment coordinates for SPIR-V targets.

  - The ‘--semantic-compat-map’ option can be used to specify that shader
    model 1-3 semantic names should be mapped to their shader model 4+ system
    value equivalents when compiling HLSL sources.

### vkd3d-dxbc

  - The ‘--list’ and ‘--list-data’ options now also output the offsets of
    sections inside the input data.

### build

  - The minimum required version of Vulkan-Headers for this release is version
    1.2.148.

  - When available, the libEGL and libOpenGL libraries are used to run the
    vkd3d tests in additional configurations. These libraries are not used by
    vkd3d itself.

  - The SONAME\_LIBDXCOMPILER configure variable can be used specify the
    shared object name of the dxcompiler library. When available, it's used to
    run the vkd3d tests in additional configurations. The dxcompiler library
    is not used by vkd3d itself.
