D3D12
|
|
=====
|
|
|
|
Overview
|
|
--------
|
|
|
|
The D3D12 driver is a Gallium driver that emits API calls for Microsoft's
|
|
:abbr:`D3D12 (Direct3D 12)` API instead of targeting a specific GPU
|
|
architecture. This can be used to get full desktop OpenGL 3.3 support on
|
|
devices that only support D3D12.
|
|
|
|
Debugging
|
|
---------
|
|
|
|
There's a few tools that are useful for debugging D3D12, such as these
|
|
environment variables:
|
|
|
|
.. envvar:: D3D12_DEBUG
|
|
|
|
Accepts the following comma-separated list of flags:
|
|
|
|
``verbose``
|
|
Enable verbose output to stdout
|
|
``blit``
|
|
Trace blit and copy resource calls
|
|
``experimental``
|
|
Enable experimental shader models feature
|
|
``dxil``
|
|
Dump DXIL during program compile
|
|
``disass``
|
|
Dump disassambly of created DXIL shader
|
|
``res``
|
|
Debug resources
|
|
``debuglayer``
|
|
Enable `debug layer`_
|
|
``gpuvalidator``
|
|
Enable `GPU validator`_
|
|
|
|
.. envvar:: DXIL_DEBUG
|
|
|
|
Accepts the following comma-separated list of flags:
|
|
|
|
``verbose``
|
|
Enable verbose output to stdout
|
|
``dump_blob``
|
|
Write shader blobs
|
|
``trace``
|
|
Trace instruction conversion
|
|
``dump_module``
|
|
dump module tree to stderr

Utilities
|
|
---------
|
|
|
|
Environment variables that control the behavior of the D3D12 driver.
|
|
|
|
.. envvar:: MESA_D3D12_DEFAULT_ADAPTER_NAME
|
|
|
|
Specifies a substring to search for when choosing a default adapter to
|
|
run on. The first adapter matching the substring is chosen. The substring
|
|
is not case sensitive.
