drm/tests: Test drm_fb_build_fourcc_list() in separate test suite

2025-06-18T08:46:03+00:00

Only sysfb drivers use drm_fb_build_fourcc_list(). The helper will be moved from format helpers to sysfb helpers. Moving the related tests to their own test suite. v3: - rename tests according to filename (José) v2: - rename filename to match tested code (Maxime) Signed-off-by: Thomas Zimmermann Reviewed-by: José Expósito Acked-by: Maxime Ripard Link: https://lore.kernel.org/r/20250616083846.221396-3-tzimmermann@suse.de

drm/tests: Create tests for drm_atomic

2025-03-20T13:45:48+00:00

We don't have a set of kunit tests for the functions under drm_atomic.h. Let's use the introduction of drm_atomic_get_connector_for_encoder() to create some tests for it and thus create that set.

drm/tests: Add kunit tests for bridges

2025-03-20T13:45:45+00:00

None of the drm_bridge function have kunit tests so far. Let's change that, starting with drm_bridge_get_current_state(). Reviewed-by: Dmitry Baryshkov Link: https://patchwork.freedesktop.org/patch/msgid/20250313-bridge-connector-v6-3-511c54a604fb@kernel.org Signed-off-by: Maxime Ripard

Now that we're tracking the output bpc count in the connector state, let's add a few tests to make sure it works as expected.

Merge v6.2-rc6 into drm-next

2023-01-31T11:23:23+00:00

Due to holidays we started -next with more -fixes in-flight than usual, and people have been asking where they are. Backmerge to get things better in sync. Conflicts: - Tiny conflict in drm_fbdev_generic.c between variable rename and missing error handling that got added. - Conflict in drm_fb_helper.c between the added call to vgaswitcheroo in drm_fb_helper_single_fb_probe and a refactor patch that extracted lots of helpers and incidentally removed the dev local variable. Readd it to make things compile. Signed-off-by: Daniel Vetter

drm/tests: reduce drm_mm_test stack usage

2022-12-23T22:08:26+00:00

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.
