config DRM_USE_DYNAMIC_DEBUG
bool "use dynamic debug to implement drm.debug"
default n
depends on BROKEN
depends on DRM
depends on DYNAMIC_DEBUG || DYNAMIC_DEBUG_CORE
depends on JUMP_LABEL
help
Use dynamic-debug to avoid drm_debug_enabled() runtime overheads.
Due to callsite counts in DRM drivers (~4k in amdgpu) and 56
bytes per callsite, the .data costs can be substantial, and
are therefore configurable.
config DRM_WERROR
bool "Compile the drm subsystem with warnings as errors"
depends on DRM && EXPERT
depends on !WERROR
default n
help
A kernel build should not cause any compiler warnings, and this
enables the '-Werror' flag to enforce that rule in the drm subsystem.
The drm subsystem enables more warnings than the kernel default, so
this config option is disabled by default.
If in doubt, say N.
config DRM_HEADER_TEST
bool "Ensure DRM headers are self-contained and pass kernel-doc"
depends on DRM && EXPERT && BROKEN
default n
help
Ensure the DRM subsystem headers both under drivers/gpu/drm and
include/drm compile, are self-contained, have header guards, and have
no kernel-doc warnings.
If in doubt, say N.
config DRM_DEBUG_MM
bool "Insert extra checks and debug info into the DRM range managers"
default n
depends on DRM
depends on STACKTRACE_SUPPORT
select STACKDEPOT
help
Enable allocation tracking of memory manager and leak detection on
shutdown.
Recommended for driver developers only.
If in doubt, say "N".

This builds unit tests for DRM. This option is not useful for
distributions or general kernels, but only for kernel
developers working on DRM and associated drivers.
For more information on KUnit and unit tests in general,
please refer to the KUnit documentation in
Documentation/dev-tools/kunit/.
If in doubt, say "N".
config DRM_TTM_KUNIT_TEST

select DRM_TTM
select DRM_BUDDY

select DRM_KUNIT_TEST_HELPERS
default KUNIT_ALL_TESTS
help
Enables unit tests for TTM, a GPU memory manager subsystem used
to manage memory buffers. This option is mostly useful for kernel
developers. It depends on (UML || COMPILE_TEST) since no other driver
which uses TTM can be loaded while running the tests.
If in doubt, say "N".
config DRM_SCHED_KUNIT_TEST
tristate "KUnit tests for the DRM scheduler" if !KUNIT_ALL_TESTS
select DRM_SCHED

help
Choose this option to build unit tests for the DRM scheduler.
Recommended for driver developers only.
If in doubt, say "N".
