VKD3D-Proton
VKD3D-Proton is a fork of VKD3D, which aims to implement the full Direct3D 12 API on top of Vulkan. The project serves as the development effort for Direct3D 12 support in Proton.
Upstream
The original project is available at WineHQ.
Priorities
Performance and compatibility are important targets, at the expense of compatibility with older drivers and systems. Modern Vulkan extensions and features are aggressively made use of to improve performance and compatibility. It is recommended to use the very latest drivers you can get your hands on for the best experience. Backwards compatibility with the vkd3d standalone API is not a goal of this project.
Cloning the repo
To clone the repo you should run:
git clone --recursive https://github.com/HansKristian-Work/vkd3d-proton
in order to pull in all the submodules which are needed for building.
Building VKD3D
Requirements:
- wine (for
widl
)- On Windows this may be substituted for Strawberry Perl as it ships
widl
and is easy to find and install -- although this dependency may be eliminated in the future.
- On Windows this may be substituted for Strawberry Perl as it ships
- Meson build system (at least version 0.51)
- glslang compiler
- Mingw-w64 compiler and headers (at least version 7.0) [for cross-builds for d3d12.dll which are default]
Building:
The simple way
Inside the VKD3D directory, run:
./package-release.sh master /your/target/directory --no-package
This will create a folder vkd3d-master
in /your/target/directory
, which contains both 32-bit and 64-bit versions of VKD3D, which can be set up in the same way as the release versions as noted above.
If you want to build natively (ie. for libvkd3d.so
), pass --native
to the build script. This option will make it build using your system's compilers.
In order to preserve the build directories for development, pass --dev-build
to the script. This option implies --no-package
. After making changes to the source code, you can then do the following to rebuild VKD3D:
# change to build.86 for 32-bit
cd /your/target/directory/build.64
ninja install
Compiling manually (cross for d3d12.dll, default)
# 64-bit build.
meson --cross-file build-win64.txt -Denable_standalone_d3d12=True --buildtype release --prefix /your/vkd3d/directory build.64
cd build.64
ninja install
# 32-bit build
meson --cross-file build-win32.txt -Denable_standalone_d3d12=True --buildtype release --prefix /your/vkd3d/directory build.86
cd build.86
ninja install
Compiling manually (native)
# 64-bit build.
meson --buildtype release --prefix /your/vkd3d/directory build.64
cd build.64
ninja install
# 32-bit build
meson --cross-file x86-linux-gnu --buildtype release --prefix /your/vkd3d/directory build.86
cd build.86
ninja install
Using VKD3D
VKD3D can be used by projects that target Direct3D 12 as a drop-in replacement at build-time with some modest source modifications.
If VKD3D is available when building Wine, then Wine will use it to support Direct3D 12 applications.
Environment variables
Most of the environment variables used by VKD3D are for debugging purposes. The environment variables are not considered a part of API and might be changed or removed in the future versions of VKD3D.
Some of debug variables are lists of elements. Elements must be separated by commas or semicolons.
VKD3D_CONFIG
- a list of options that change the behavior of libvkd3d.- vk_debug - enables Vulkan debug extensions.
VKD3D_DEBUG
- controls the debug level for log messages produced by libvkd3d. Accepts the following values: none, err, fixme, warn, trace.VKD3D_SHADER_DEBUG
- controls the debug level for log messages produced by libvkd3d-shader. SeeVKD3D_DEBUG
for accepted values.VKD3D_LOG_FILE
- If set, redirectsVKD3D_DEBUG
logging output to a file instead.VKD3D_VULKAN_DEVICE
- a zero-based device index. Use to force the selected Vulkan device.VKD3D_DISABLE_EXTENSIONS
- a list of Vulkan extensions that libvkd3d should not use even if available.VKD3D_SHADER_DUMP_PATH
- path where shader bytecode is dumped.VKD3D_TEST_DEBUG
- enables additional debug messages in tests. Set to 0, 1 or 2.VKD3D_TEST_FILTER
- a filter string. Only the tests whose names matches the filter string will be run, e.g.VKD3D_TEST_FILTER=clear_render_target
. Useful for debugging or developing new tests.VKD3D_TEST_PLATFORM
- can be set to "wine", "windows" or "other". The test platform controls the behavior of todo(), todo_if(), bug_if() and broken() conditions in tests.VKD3D_TEST_BUG
- set to 0 to disable bug_if() conditions in tests.VKD3D_PROFILE_PATH
- If profiling is enabled in the build, a profiling block is emitted to${VKD3D_PROFILE_PATH}.${pid}
.
CPU profiling (development)
Pass -Denable_profiling=true
to Meson to enable a profiled build. With a profiled build, use VKD3D_PROFILE_PATH
environment variable.
The profiling dumps out a binary blob which can be analyzed with programs/vkd3d-profile.py
.
The profile is a trivial system which records number of iterations and total ticks (ns) spent.
It is easy to instrument parts of code you are working on optimizing.
