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". config DRM_KUNIT_TEST_HELPERS tristate depends on DRM && KUNIT select DRM_KMS_HELPER help KUnit Helpers for KMS drivers. config DRM_KUNIT_TEST tristate "KUnit tests for DRM" if !KUNIT_ALL_TESTS depends on DRM && KUNIT && MMU select DRM_BRIDGE_CONNECTOR select DRM_BUDDY select DRM_DISPLAY_DP_HELPER select DRM_DISPLAY_HDMI_STATE_HELPER select DRM_DISPLAY_HELPER select DRM_EXEC select DRM_EXPORT_FOR_TESTS if m select DRM_GEM_SHMEM_HELPER select DRM_KUNIT_TEST_HELPERS select DRM_LIB_RANDOM select PRIME_NUMBERS default KUNIT_ALL_TESTS help 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 tristate "KUnit tests for TTM" if !KUNIT_ALL_TESTS default n depends on DRM && KUNIT && MMU && (UML || COMPILE_TEST) select DRM_TTM select DRM_BUDDY select DRM_EXPORT_FOR_TESTS if m 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 depends on DRM && KUNIT default KUNIT_ALL_TESTS help Choose this option to build unit tests for the DRM scheduler.
