Vkd3d is a 3D graphics library built on top of Vulkan. It has an API very similar, but not identical, to Direct3D 12. Wine uses vkd3d libraries for its implementation of Direct3D 12.

Building

Getting the vkd3d source

You can download the Vkd3d source code as a tarball, but if you plan to do any actual testing or developing, you'll want to use git.

To grab the source code, just enter the following command:

git clone git://source.winehq.org/git/vkd3d.git/

Compiling

Enter the following commands:

./autogen.sh
./configure
make

See also the README file.

In order to build 32-bit libraries:

../vkd3d/configure --build=i686-pc-linux-gnu "CPPFLAGS=-m32" "LDFLAGS=-m32"

Building Wine with Direct3D 12 support

Wine uses pkg-config to find vkd3d libraries. If vkd3d libraries are installed system-wide, the Wine configure script should find the vkd3d libraries automatically. You can also use PKG_CONFIG_PATH, VKD3D_CFLAGS or VKD3D_LIBS to override pkg-config search path, C compiler flags for libvkd3d, or linker flags for libvkd3d, e.g.

../wine-git/configure PKG_CONFIG_PATH=$HOME/src/vulkan/install/lib/pkgconfig

Debugging

Debug output

Vkd3d provides VKD3D_DEBUG and VKD3D_SHADER_DEBUG environment variables to control debug log messages. The debug variables can be set to one of the following debug log levels: none, err, fixme, warn, trace.

See the README file for description of all debug environment variables.

Vulkan validation layers

Enable validation layers in a standard way:

export VK_INSTANCE_LAYERS=VK_LAYER_LUNARG_standard_validation

You may also want to enable Vulkan debug extensions in vkd3d:

VKD3D_CONFIG=vk_debug

Tests

Use the following command to run tests:

make check

Tests can also be run individually, for example:

 make tests/d3d12 && ./tests/d3d12

To cross-compile tests for Windows run the following command:

make crosstest

Shader tests

Some tests include compiled shader bytecode. Shader bytecode should be generated with /Qstrip_debug /Qstrip_reflect options. For example:

fxc /Qstrip_debug /Qstrip_reflect /T ps_5_0 source.hlsl /Fo output.dxbc
