There's a few tools that are useful for debugging D3D12, such as these
environment variables:
-.. envvar:: D3D12_DEBUG <flags> ("")
+.. envvar:: D3D12_DEBUG
+
+ Accepts the following comma-separated list of flags:
``verbose``
Enable verbose output to stdout
``gpuvalidator``
Enable `GPU validator`_
-.. envvar:: DXIL_DEBUG <flags> ("")
+.. envvar:: DXIL_DEBUG
+
+ Accepts the following comma-separated list of flags:
``verbose``
Enable verbose output to stdout
Environment variables that control the behavior of the D3D12 driver.
-.. envvar:: MESA_D3D12_DEFAULT_ADAPTER_NAME <string> ("")
+.. 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
These are some Lima-specific environment variables that may aid in
debugging. None of this is required for normal use.
-.. envvar:: LIMA_DEBUG <flags> ("")
+.. envvar:: LIMA_DEBUG
accepts the following comma-separated list of flags:
disable multi job optimization
-.. envvar:: LIMA_CTX_NUM_PLB <int> (None)
+.. envvar:: LIMA_CTX_NUM_PLB
set number of PLB per context (used for development purposes)
-.. envvar:: LIMA_PLB_MAX_BLK <int> (None)
+.. envvar:: LIMA_PLB_MAX_BLK
set PLB max block (used for development purposes)
-.. envvar:: LIMA_PPIR_FORCE_SPILLING <int> (None)
+.. envvar:: LIMA_PPIR_FORCE_SPILLING
force spilling of variables in PPIR (used for development purposes)
-.. envvar:: LIMA_PLB_PP_STREAM_CACHE_SIZE <int> (None)
+.. envvar:: LIMA_PLB_PP_STREAM_CACHE_SIZE
set PP stream cache size (used for development purposes)

-.. envvar:: GALLIUM_PRINT_OPTIONS <bool> (false)

- This option controls if the debug variables should be printed to stderr. This
- is probably the most useful variable, since it allows you to find which
- variables a driver uses.

-.. envvar:: GALLIUM_TRACE <string> ("")
+.. envvar:: GALLIUM_TRACE
If set, this variable will cause the :ref:`trace` output to be written to the
specified file. Paths may be relative or absolute; relative paths are relative
to the working directory. For example, setting it to "trace.xml" will cause
the trace to be written to a file of the same name in the working directory.
-.. envvar:: GALLIUM_TRACE_TC <bool> (false)
+.. envvar:: GALLIUM_TRACE_TC
If enabled while :ref:`trace` is active, this variable specifies that the threaded context
should be traced for drivers which implement it. By default, the driver thread is traced,
which will include any reordering of the command stream from threaded context.
-.. envvar:: GALLIUM_TRACE_TRIGGER <string> ("")
+.. envvar:: GALLIUM_TRACE_TRIGGER
If set while :ref:`trace` is active, this variable specifies a filename to monitor.
Once the file exists (e.g., from the user running 'touch /path/to/file'), a single
frame will be recorded into the trace output.
Paths may be relative or absolute; relative paths are relative to the working directory.
-.. envvar:: GALLIUM_DUMP_CPU <bool> (false)
+.. envvar:: GALLIUM_DUMP_CPU
- Dump information about the current CPU that the driver is running on.
+ Enable dumping of information about the current CPU that the driver is running on.
-.. envvar:: TGSI_PRINT_SANITY <bool> (false)
+.. envvar:: TGSI_PRINT_SANITY
- Gallium has a built-in shader sanity checker. This option controls whether
- the shader sanity checker prints its warnings and errors to stderr.
+ Gallium has a built-in shader sanity checker. This boolean option controls

-.. envvar:: DRAW_USE_LLVM <bool> (false)
+.. envvar:: DRAW_USE_LLVM
Whether the :ref:`Draw` module will attempt to use LLVM for vertex and geometry shaders.
