``VC4_DEBUG=help`` to print a list of available options.
Shared Vulkan driver environment variables
------------------------------------------
.. envvar:: MESA_VK_MEMORY_TRACE
enable memory tracing and exporting RMV captures (requires the
``scripts/setup.sh`` script in the Radeon Developer Tools folder to be
run beforehand). ``MESA_VK_MEMORY_TRACE=n`` dumps data
after n frames. Currently, only RADV implements this.
.. envvar:: MESA_VK_MEMORY_TRACE_TRIGGER
enable trigger file-based memory tracing. (e.g.
``export MESA_VK_MEMORY_TRACE_TRIGGER=/tmp/memory_trigger`` and then
``touch /tmp/memory_trigger`` to capture a memory trace).
Running ``scripts/setup.sh`` beforehand is required.
