2022-12-23drm/tests: reduce drm_mm_test stack usageArnd Bergmann
The check_reserve_boundaries function uses a lot of kernel stack, and it gets inlined by clang, which makes __drm_test_mm_reserve use even more of it, to the point of hitting the warning limit: drivers/gpu/drm/tests/drm_mm_test.c:344:12: error: stack frame size (1048) exceeds limit (1024) in '__drm_test_mm_reserve' [-Werror,-Wframe-larger-than] When building with gcc, this does not happen, but the structleak plugin can similarly increase the stack usage and needs to be disabled, as we do for all other kunit users.

2022-11-02drm/tests: Add back seed value informationArthur Grillo
As reported by Michał, the drm_mm and drm_buddy unit tests lost the printk with seed value after they were refactored into KUnit. Add kunit_info with seed value information to assure reproducibility.

2022-10-11treewide: use get_random_u32() when possibleJason A. Donenfeld
The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.

2022-09-14drm/tests: Change "igt_" prefix to "drm_test_"Maíra Canal
With the introduction of KUnit, IGT is no longer the only option to run the DRM unit tests, as the tests can be run through kunit-tool or on real hardware with CONFIG_KUNIT. Therefore, remove the "igt_" prefix from the tests and replace it with the "drm_test_" prefix, making the tests' names independent from the tool used.
