- Update to version 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(), 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. (forwarded request 1132181 from tobijk)
