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. + + +# What's new in vkd3d 1.9 (21 Sep 2023) + +### libvkd3d + +- Copying between depth/stencil and colour formats in + ID3D12GraphicsCommandList::CopyResource() is supported. +- The ID3D12Fence1 interface is supported. + + +### libvkd3d-shader + +- vkd3d_shader_scan() supports retrieving descriptor information for ‘d3dbc’ + shaders. This is one of the requirements for eventual SPIR-V generation from + ‘d3dbc’ sources. + +- New features for the HLSL source type: + - Support for the following intrinsic functions: + - clip() + - ddx_coarse() and ddy_coarse() + - ddx_fine() and ddy_fine() + - tex1D(), tex2D(), texCUBE(), and tex3D() + - Constant folding support for more expression types. In particular: + - comparison operators + - floating-point min() and max() + - logical ‘and’ and ‘or’ + - dot products + - square roots + - logarithms + - Support for multi-sample texture object declarations without explicit + sample counts in shader model 4.1 and later shaders. + - Support for using constant expressions as sample counts in multi-sample + texture object declarations. + - Support for variable initialisers using variables declared earlier in the + same declaration list. E.g., ‘float a = 1, b = a, c = b + 1;’. + - The GetDimensions() texture object method is implemented. + - Matrix swizzles are implemented. + - Parser support for if-statement attributes like ‘[branch]’ and + ‘[flatten]’. + - Support for the ‘inline’ function modifier. + +- Previously, vkd3d_shader_compile() would in some cases return VKD3D_OK + despite compilation failing when targeting legacy Direct3D bytecode. These + cases have been fixed. + +- Various HLSL preprocessor fixes for edge cases related to stringification. + +- SPIR-V target support for the ‘linear noperspective centroid’ input + interpolation mode. + +- New interfaces: + - The vkd3d_shader_scan_signature_info structure extends the + vkd3d_shader_compile_info structure, and can be used to retrieve + descriptions of ‘dxbc-tpf’ and ‘d3dbc’ shader inputs and outputs. + - vkd3d_shader_free_scan_signature_info() is used to free + vkd3d_shader_scan_signature_info structures. + - The VKD3D_SHADER_COMPILE_OPTION_PACK_MATRIX_ORDER compile option can be + used to specify the default matrix packing order for HLSL sources. + - The vkd3d_shader_varying_map_info structure extends the + vkd3d_shader_compile_info structure, and can be used to specify a mapping + between the outputs of a shader stage and the inputs of the next shader + stage. + - vkd3d_shader_build_varying_map() is used to build a mapping between the + outputs of a shader stage and the inputs of the next shader stage. + - The VKD3D_SHADER_DESCRIPTOR_INFO_FLAG_RAW_BUFFER flag returned as part of + the vkd3d_shader_descriptor_info structure indicates the descriptor refers + to a byte-addressed (‘raw’) buffer resource. + + +### vkd3d-compiler + +- The ‘--matrix-storage-order’ option can used to specify the default matrix + storage order for HLSL sources. + + +### vkd3d-dxbc + +- vkd3d-dxbc is a new utility that can be used to inspect the contents of DXBC + blobs. + + +# What's new in vkd3d 1.8 (22 Jun 2023) + +### libvkd3d + +- Performance improvements have been made to the code that handles descriptor + updates. In some applications the improvement can be quite significant. + +- Host-visible descriptor heaps are persistently mapped on creation. Some + applications access resource data from the CPU after calling Unmap(), and + that's supposed to work in practice. + +- 1-dimensional texture unordered-access views and shader resource views are + implemented. + +- Shader resource view, unordered access view, and constant buffer view root + descriptors with NULL GPU addresses are supported. + +- Direct3D 12 descriptor heap destruction is delayed until all contained + resources are destroyed. + + +### libvkd3d-shader + +- New features for the HLSL source type: + - Support for the ternary conditional operator "?:". + - Support for "discard" statements. + - Support for the "packoffset" keyword. + - Support for semantics on array types. + - Support for RWBuffer loads and stores. + - Register allocation for arrays and structures of resources and samplers + is implemented. + - Support for the SV_IsFrontFace pixel shader system-value semantics. + - Support for using constant expressions as array sizes and indices. + - Support for dynamic selection of vector components. + - Support for the following intrinsic functions: + - D3DCOLORtoUBYTE4() + - any() + - asfloat() + - ddx() and ddy() + - fmod() + - log(), log2(), and log10() + - sign() + - trunc() + - The SampleBias(), SampleCmp(), SampleCmpLevelZero(), and SampleGrad() + texture object methods are implemented. + - Support for the case-insensitive variants of the "vector" and "matrix" + data types. + - Parser support for the "unroll" loop attribute. A warning is output for + "unroll" without iteration count, and an error is output when an iteration + count is specified. Actual unrolling is not implemented yet. + - Parser support for RWStructuredBuffer resources. + - Parser support for SamplerComparisonState objects. Note that outputting + compiled effects is not supported yet, but parsing these allows shaders + containing SamplerComparisonState state objects to be compiled. + +- More improvements to HLSL support for the Direct3D shader model 1/2/3 + profiles. + +- The section alignment of DXBC blobs produced by + vkd3d_shader_serialize_dxbc() matches those produced by d3dcompiler more + closely. + +- The "main" function for shaders produced by the SPIR-V target is always + terminated, even when the source was a TPF shader without explicit "ret" + instruction. + +- Relative addressing of shader input registers is supported by SPIR-V + targets. + + +# What's new in vkd3d 1.7 (23 Mar 2023) + +### libvkd3d-shader + +- New features for the HLSL source type: + - Support for calling user-defined functions. + - Support for array parameters to user-defined functions. + - Much improved support for the Direct3D shader model 1/2/3 profiles. + - Support for the SV_DispatchThreadID, SV_GroupID, and SV_GroupThreadID + compute shader system-value semantics. + - Support for the optional "offset" parameter of the texture object Load() + method. + - Support for the all() intrinsic function. + - Support for the distance() intrinsic function. + - Support for the exp() and exp2() intrinsic functions. + - Support for the frac() intrinsic function. + - Support for the lit() intrinsic function. + - Support for the reflect() intrinsic function. + - Support for the sin() and cos() intrinsic functions. + - Support for the smoothstep() intrinsic function. + - Support for the sqrt() and rsqrt() intrinsic functions. + - Support for the step() intrinsic function. + - Support for the transpose() intrinsic function. + - Support for the case-insensitive variants of the "float" and "dword" data + types. + - Partial support for minimum precision data types like "min16float". These + are currently interpreted as their regular counterparts. + - Improved constant propagation support, in particular to constant + propagation through swizzles. + +- HLSL static variables are now properly zero-initialised. + +- The Direct3D shader model 4 and 5 disassembler outputs sample counts for + multi-sampled resource declarations. + +- New interfaces: + - vkd3d_shader_parse_dxbc() provides support for parsing DXBC blobs. + - vkd3d_shader_serialize_dxbc() provides support for serialising DXBC blobs. + - vkd3d_shader_free_dxbc() is used to free vkd3d_shader_dxbc_desc + structures, as returned by vkd3d_shader_parse_dxbc(). + - The VKD3D_SHADER_COMPILE_OPTION_WRITE_TESS_GEOM_POINT_SIZE compile option + can be used to specify whether SPIR-V shaders targeting Vulkan + environments should write point sizes for geometry and tessellation + shaders. If left unspecified, point sizes will be written. + + +# What's new in vkd3d 1.6 (7 Dec 2022) + +### libvkd3d-shader + +- New features for the HLSL source type: + - Initial support for compute shaders. + - Improved support for initialisation and assignment of compound objects + like structures and arrays, including casts and implicit conversions. + - Support for loads and stores of texture resource unordered-access views. + - Support for function attributes. In particular, the required "numthreads" + attribute for compute shader entry points is now supported. + - Support for the asuint() intrinsic function. + - Support for the length() intrinsic function. + - Support for the normalize() intrinsic function. + - Support for integer division and modulus. + - Support for taking the absolute value of integers. + - Support for floating-point modulus. + + +- New interfaces: + - The VKD3D_SHADER_DESCRIPTOR_INFO_FLAG_UAV_ATOMICS descriptor info flag is + used to indicate that atomic operations are used on unordered-access view + descriptors. + + +### libvkd3d-common + +- vkd3d debug output is prefixed with "vkd3d:" in order to make it easier to + distinguish from output produced by applications or other libraries. + + +### demos + +- The demos now use libvkd3d-shader to compile HLSL shaders at run-time. + + +# What's new in vkd3d 1.5 (22 Sep 2022) + +### libvkd3d-shader + +- New features for the HLSL source type: + - Improved support for HLSL object types (like e.g. ‘Texture2D’) inside + structures and arrays. + - Implicitly sized array initialisers. + - Support for the dot() intrinsic function. + - Support for the ldexp() intrinsic function. + - Support for the lerp() intrinsic function. + - Support for the logical ‘and’, ‘or’, and ‘not’ operators in shader model 4 + and 5 targets. + - Support for casts from ‘bool’ types in shader model 4 and 5 targets. + - Constant folding for integer bitwise operations. + - Constant folding for integer min() and max(). + +- New interfaces: + - The VKD3D_SHADER_COMPILE_OPTION_TYPED_UAV compile option can be used to + specify the SPIR-V format to use for typed unordered access view loads. + When set to ‘Unknown’, and the ‘shaderStorageImageReadWithoutFormat’ + feature is enabled in the target environment, this allows typed loads from + multicomponent format unordered access views. If left unspecified, a R32 + format will be used, like in previous versions of libvkd3d-shader. + + +# What's new in vkd3d 1.4 (22 Jun 2022) + +### libvkd3d + +- A new descriptor heap implementation using the VK_EXT_descriptor_indexing + extension. In particular, the new implementation is more efficient when + large descriptor heaps are used by multiple command lists. The new + ‘virtual_heaps’ configuration option can be used to select the original + implementation even when the VK_EXT_descriptor_indexing extension is + available. + +- A new fence implementation using the VK_KHR_timeline_semaphore extension. + The new implementation addresses a number of edge cases the original + implementation was unable to, as well as being somewhat more efficient. + +- When the VK_EXT_robustness2 extension is available, it is used to implement + null views. This more accurately matches Direct3D 12 behaviour. For example, + all reads from such a null view return zeroes, while that isn't necessarily + the case for out-of-bounds reads with the original implementation. + +- New interfaces: + - vkd3d_set_log_callback() allows writing log output via a custom callback. + This can be used to integrate vkd3d's log output with other logging + systems. + + +### libvkd3d-shader + +- New features for the HLSL source type: + - Support for integer arithmetic, bitwise and shift operations. + - Support for matrix and vector subscripting. + - Support for the mul() intrinsic function. + - Support for matrix copying, casting, and entry-wise operations. + - Support for complex initialisers. + - Support for the ‘nointerpolation’ modifier. This modifier is applied by + default to integer variables. + - Support for the SV_VertexID semantic. + - Support for matrix-typed varyings. + - Constant folding for a number of operators. + - Copy propagation across branches and loops. This allows use of non-numeric + variables anywhere in a program, as well as more optimised code for + accessing numeric variables within branches and loops. + +- The disassembler supports the shader model 5 ‘msad’ instruction. + +- New interfaces: + - vkd3d_shader_set_log_callback() allows writing log output via a custom + callback. + + +### libvkd3d-utils + +- New interfaces: + - vkd3d_utils_set_log_callback() allows writing log output via a custom + callback. + + +### build + +- The minimum required version of Vulkan-Headers and SPIRV-Headers for this + release is version 1.2.139. + +- The SONAME_LIBVULKAN configure variable can be used to specify the shared + object name of the Vulkan library. Because vkd3d loads the Vulkan library + dynamically, specifying this removes the need for a Vulkan import library at + build time. + +- The ‘crosstests’ target no longer builds Win32/PE demos or tests when these + were not enabled at configure time. + + +# What's new in vkd3d 1.3 (2 Mar 2022) + +### libvkd3d + +- Newly implemented Direct3D 12 features: + - Root signature support for unbounded descriptor tables. + - Unordered-access view counters in pixel shaders. These were previously + only supported in compute shaders. + - Output merger logical operations. + - Retrieving CPU/GPU timestamp calibration values. This requires support for + the VK_EXT_calibrated_timestamps extension. + - The ‘mirror_once’ texture addressing mode. This requires support for the + VK_KHR_sampler_mirror_clamp_to_edge extension. + +- New interfaces: + - The vkd3d_host_time_domain_info structure extends the + vkd3d_instance_create_info structure, and can be used to specify how to + convert between timestamps and tick counts. If left unspecified, a tick + is assumed to take 100 nanoseconds. + +- Various bug fixes. + + +### libvkd3d-shader + +- New features: + - Initial support for HLSL compilation and preprocessing. This is an ongoing + effort; although support for many features is already implemented, support + for many more isn't yet. + - Support for disassembling Direct3D byte-code shaders to Direct3D assembly. + - Support for parsing the legacy Direct3D byte-code format used by Direct3D + shader model 1, 2, and 3 shaders. In the current vkd3d-shader release, + only Direct3D assembly is supported as a target for these; we intend to + support SPIR-V as a target in a future release. + +- New features for the SPIR-V target: + - Support for various aspects of Direct3D shader model 5.1 descriptor + arrays, including unbounded descriptor arrays, UAV counter arrays, dynamic + indexing of descriptor arrays, and non-uniform indexing of descriptor + arrays. With the exception of some special cases, this requires support + for the SPV_EXT_descriptor_indexing extension in the target environment. + - Support for double precision floating-point operations. + - Support for indirect addressing of tessellation control shader inputs. + - Stencil export. I.e., writing stencil values from shaders. This requires + support for the SPV_EXT_shader_stencil_export extension in the target + environment. + - Support for the Direct3D shader model 4+ ‘precise’ modifier. + - Support for Direct3D shader model 4+ global resource memory barriers. + +New interfaces: + - vkd3d_shader_preprocess() provides support for preprocessing shaders. + - The vkd3d_shader_preprocess_info structure extends the + vkd3d_shader_compile_info structure, and can be used to specify + preprocessing parameters like preprocessor macro definitions. + - The vkd3d_shader_hlsl_source_info structure extends the + vkd3d_shader_compile_info structure, and can be used to specify HLSL + compilation parameters like the target profile and entry point. + - The vkd3d_shader_descriptor_offset_info structure extends the + vkd3d_shader_interface_info structure, and can be used to specify offsets + into descriptor arrays referenced by shader interface bindings. This + allows mapping multiple descriptor arrays in a shader to a single binding + point in the target environment, and helps with mapping between the + Direct3D 12 and Vulkan binding models. + - The VKD3D_SHADER_COMPILE_OPTION_API_VERSION compile option can + be used to specify the version of the libvkd3d-shader API the + application is targetting. If left unspecified, + VKD3D_SHADER_API_VERSION_1_2 will be used. + +- Various shader translation fixes, for tessellation shaders in particular. + + +### vkd3d-compiler + +- New source and target types: + - The ‘hlsl’ source type specifies High Level Shader Language source code. + - The ‘d3d-asm’ target type specifies Direct3D assembly shaders. + - The ‘d3dbc’ format specifies legacy Direct3D byte-code, which is used for + Direct3D shader model 1, 2, and 3 shaders. + - The existing ‘dxbc-tpf’ format can now also be used as a target format. + +- New command line options: + - ‘-E’ can be used to specify the input should only be preprocessed. + - ‘-e’/‘--entry’ can be used to specify the entry point for HLSL and/or + SPIR-V shaders. + - ‘-p’/‘--profile’ can be used to specify the target profile for HLSL + shaders. + +- When no source type is explicitly specified, vkd3d-compiler will attempt to + determine the source type from the provided input. Note that this is + intended as a convenience for interactive usage only, and the heuristics + used are subject to future change. Non-interactive usage of vkd3d-compiler, + for example in build scripts, should always explicitly specify source and + target types. + +- When no target type is explicitly specified, a default will be chosen based + on the source type. Like the earlier mentioned source type detection, this + is intended for interactive usage only. + +- vkd3d-compiler will default to colour output if it can determine that the + output is a colour-capable teleprinter. + +- New environment variables: + - NO_COLOUR/NO_COLOR can be used to disable default colour output. + See the README for more detailed descriptions and how to use these. + + +### libvkd3d-utils + +- New interfaces: + - D3DCreateBlob() provides support for creating ID3DBlob objects. + - D3DPreprocess() provides support for preprocessing HLSL source code. + - D3DCompile() and D3DCompile2() provide support for compiling HLSL source + code. + + +### build + +- The ‘gears’ and ‘triangle’ demo applications are installed as ‘vkd3d-gears’ + and ‘vkd3d-triangle’. These were originally intended more as documentation + than as end-user executables, but there's some value in using them for + diagnostic purposes, much like e.g. ‘glxgears’. + +- The VULKAN_LIBS configure variable is used when detecting the Vulkan + library. + +- Builds for the Microsoft Windows target platform no longer require support + for POSIX threads. Windows synchronisation primitives are used instead. + +- If ncurses is available, it will be use by vkd3d-compiler to determine the + capabilities of the connected teleprinter, if any. + + +# What's new in vkd3d 1.2 (22 Sep 2020) + +### libvkd3d + +- Newly implemented Direct3D 12 features: + - Multi-sampling. + - Reserved resources. + - Instance data step rates. This requires the + VK_EXT_vertex_attribute_divisor extension. + - ‘Private data’ APIs for all interfaces. + - Shader-resource view component mappings. + - Indirect indexed draws. + - Indirect draws with a count buffer. This requires the + VK_KHR_draw_indirect_count extension. + - Stream output and stream output queries. This requires the + VK_EXT_transform_feedback extension. + - Predicated/conditional rendering. + - Primitive restart. + - Depth rendering without a pixel shader. + - Depth clipping. This requires the VK_EXT_depth_clip_enable extension. + - Rasteriser discard. + - Dual-source blending. + - Mapping placed resources. + - The ReadFromSubresource() and WriteToSubresource() ID3D12Resource methods. + - Simultaneous access to resources from multiple queues. + - Null-views. I.e., views without an underlying resource. + - Several more feature support queries. + +- New interfaces: + - vkd3d_serialize_versioned_root_signature() and + vkd3d_create_versioned_root_signature_deserializer() provide support for + versioned root signatures. + - The vkd3d_application_info structure extends the + vkd3d_instance_create_info structure, and can be used to pass information + about the application to libvkd3d. It is analogous to the + VkApplicationInfo structure in Vulkan. Its ‘api_version’ field should be + set to the version of the libvkd3d API that the application targets. + - The vkd3d_optional_device_extensions_info structure extends the + vkd3d_device_create_info structure, and can be used to pass a list of + device extensions to enable only when available to libvkd3d. It is + analogous to the vkd3d_optional_instance_extensions_info structure for + instance extensions. + +- New environment variables: + - VKD3D_CONFIG can be used to set options that change the behaviour of + libvkd3d. + - VKD3D_TEST_BUG can be used to disable bug_if() conditions in the test + suite. + - VKD3D_TEST_FILTER can be used to control which tests are run. + - VKD3D_VULKAN_DEVICE can be used to override the Vulkan physical device + used by vkd3d. + See the README for more detailed descriptions and how to use these. + +- When the VK_KHR_dedicated_allocation extension is available, dedicated + allocations may be used for committed resources. + +- When the VK_KHR_image_format_list extension is available, it will be used to + inform the driver about the view formats that a particular mutable Vulkan + image can be used with. This improves performance on some Vulkan + implementations. + +- When the VK_EXT_debug_marker extension is available, object names set with + the ID3D12Object SetName() method will be propagated to the underlying + Vulkan objects. + +- Unordered-access view clears are supported on more formats. Previously these + were limited to integer formats for texture resources, and single component + integer formats for buffer resources. + +- When the D24_UNORM_S8_UINT format is not supported by the Vulkan + implementation, the D32_SFLOAT_S8_UINT format will be used instead to + implement the D24_UNORM_S8_UINT and related DXGI formats. This is required + because the DXGI D24_UNORM_S8_UINT format is mandatory, while the Vulkan + D24_UNORM_S8_UINT format is optional. + +- Various bug fixes. + + +### libvkd3d-shader + +- libvkd3d-shader is now available as a public instead of an internal library. + +- New features: + - Tessellation shaders. + - Root signature version 1.1 serialisation, deserialisation, and conversion. + - Multi-sample masks. + - Per-sample shading. + - Early depth/stencil test. + - Conservative depth output. + - Dual-source blending. + - Stream output. + - Viewport arrays. + +- Support for OpenGL SPIR-V target environments. This allows SPIR-V produced + by libvkd3d-shader to be used with GL_ARB_gl_spirv. This includes support + for OpenGL atomic counters and combined samplers. + +- Preliminary support for shader model 5.1 shaders. This is still a work in + progress. Notably, support for resource arrays is not yet implemented. + +- When the SPV_EXT_demote_to_helper_invocation is available, it will be used + to implement the ‘discard’ shader instruction instead of using SpvOpKill. In + particular, this ensures the ‘deriv_rtx’ and ‘deriv_rty’ instruction return + accurate results after a (conditional) ‘discard’ instruction. + +- Support for using SPIR-V specialisation constants for shader parameters. + +- Support for more shader instructions: + - bufinfo, + - eval_centroid, + - eval_sample_index, + - ld2ms, + - sample_b, + - sample_d, + - sample_info, + - samplepos. + +- When built against SPIRV-Tools, libvkd3d-shader can produce SPIR-V shaders + in text form. + +- libvkd3d-shader now has its own environment variable (VKD3D_SHADER_DEBUG) to + control debug output. + +- Various shader translation fixes. + + +### vkd3d-compiler + +- When supported by libvkd3d-shader, text form SPIR-V is available as a target + format, in addition to the existing binary form SPIR-V target format. + +- Input from standard input, and output to standard output is supported. + + +### libvkd3d-utils + +- To specify the libvkd3d API version to use when creating vkd3d instances, + define VKD3D_UTILS_API_VERSION to the desired version before including + vkd3d_utils.h. If VKD3D_UTILS_API_VERSION is not explicitly defined, + VKD3D_API_VERSION_1_0 will be used. + +- Support for versioned root signatures is provided by the + D3D12SerializeVersionedRootSignature() and + D3D12CreateVersionedRootSignatureDeserializer() entry points. + + +### build + +- The minimum required version of Vulkan-Headers and SPIRV-Headers for this + release is version 1.1.113. + +- The minimum required version of widl for this release is version 3.20. + +- If doxygen is available, it will be used to build API documentation. By + default, documentation will be generated in HTML and PDF formats. + +- If debug logs are not required or desired, defining VKD3D_NO_TRACE_MESSAGES + and VKD3D_NO_DEBUG_MESSAGES will prevent them from being included in the + build. For example, a release build may want to configure with + ‘CPPFLAGS="-DNDEBUG -DVKD3D_NO_TRACE_MESSAGES -DVKD3D_NO_DEBUG_MESSAGES"’. + +- Microsoft Windows is now a supported target platform. To create a build for + Windows, either cross-compile by configuring with an appropriate --host + option like for example ‘--host=x86_64-w64-mingw32’, or build on Windows + itself using an environment like MSYS2 or Cygwin. + + +# What's new in vkd3d 1.1 (5 Oct 2018) + +### libvkd3d + +- Initial support for memory heaps and placed resources. + +- Improved support for resource views. + +- ClearUnorderedAccessViewUint() is implemented for textures. + +- Blend factor is implemented. + +- Performance improvements. + +- A new interface is available for enabling additional Vulkan instance + extensions. + +- A new public function is available for mapping VkFormats to DXGI_FORMATs. + +- Support for more DXGI formats. + +- Various bug fixes. + + +### libvkd3d-shader + +- Support for geometry shaders. + +- Pretty printing is implemented for shader code extracted from DXBC. + +- Clip and cull distances are supported. + +- Support for more shader instructions: + - round_ne, + - sincos, + - ineg, + - continue, + - continuec, + - gather4_po, + - gather4_po_c, + - gather4_c. + +- Texel offsets are supported. + +- Various shader translation fixes. + + +### libvkd3d-utils + +- Vulkan WSI extensions are detected at runtime. + + +### build + +- Demos are not built by default. + +- libxcb is now an optional dependency required only for demos. + +- MoltenVK is supported. + + +# What's included in vkd3d 1.0 (23 May 2018) + +### libvkd3d + +- libvkd3d is the main component of the vkd3d project. It's a 3D graphics + library built on top of Vulkan with an API very similar to Direct3D 12. + +- A significant number of Direct3D 12 features are implemented, including: + - Graphics and compute pipelines. + - Command lists, command allocators and command queues. + - Descriptors and descriptor heaps. + - Root signatures. + - Constant buffer, shader resource, unordered access, render target and depth + stencil views. + - Samplers. + - Static samplers. + - Descriptors copying. + - Committed resources. + - Fences. + - Queries and query heaps. + - Resource barriers. + - Root constants. + - Basic support for indirect draws and dispatches. + - Basic support for command signatures. + - Various Clear*() methods. + - Various Copy*() methods. + + +### libvkd3d-shader + +- libvkd3d-shader is a library which translates shader model 4 and 5 bytecode + to SPIR-V. In this release, libvkd3d-shader is an internal library. Its API + isn't set in stone yet. + +- Vertex, pixel and compute shaders are supported. Also, very simple geometry + shaders should be translated correctly. Issues are expected when trying to + translate tessellation shaders or more complex geometry shaders. + +- A significant number of shader instructions are supported in this release, + including: + - Arithmetic instructions. + - Bit instructions. + - Comparison instructions. + - Control flow instructions. + - Sample, gather and load instructions. + - Atomic instructions. + - UAV instructions. + +- Root signature serialization and deserialization is implemented. + +- Shader model 4 and 5 bytecode parser is imported from wined3d. + +- Shader model 5.1 is not supported yet. + + +### libvkd3d-utils + +- libvkd3d-utils contains simple implementations of various functions which + might be useful for source ports of Direct3D 12 applications. + + +### demos + +- A simple hello triangle Direct3D 12 demo. +- A Direct3D 12 port of glxgears.
