drm/tests: shmem: Swap names of export tests

2026-03-04T12:21:37+00:00

[ Upstream commit 89f23d42006630dd94c01a8c916f8c648141ad8e ] GEM SHMEM has 2 helpers for exporting S/G tables. Swap the names of the rsp. tests, so that each matches the helper it tests.

drm/tests: Do not use drm_fb_blit() in format-helper tests

2025-08-28T14:31:12+00:00

[ Upstream commit 5a4856e0e38109ba994f369962f054ecb445c098 ] Export additional helpers from the format-helper library and open-code drm_fb_blit() in tests. Prepares for the removal of drm_fb_blit(). Only sysfb drivers use drm_fb_blit(). The function will soon be removed from format helpers and be refactored within sysfb helpers.

drm/tests: shmem: Fix memleak

2025-05-09T07:50:43+00:00

[ Upstream commit 48ccf21fa8dc595c8aa4f1d347b593dcae0727d0 ] The drm_gem_shmem_test_get_pages_sgt() gets a scatter-gather table using the drm_gem_shmem_get_sg_table() function and rightfully calls sg_free_table() on it. However, it's also supposed to kfree() the returned sg_table, but doesn't. This leads to a memory leak, reported by kmemleak. Fix it by adding a kunit action to kfree the sgt when the test ends.

drm/tests: helpers: Create kunit helper to destroy a drm_display_mode

2025-04-20T08:15:07+00:00

[ Upstream commit 13c1d5f3a7fa7b55a26e73bb9e95342374a489b2 ] A number of test suites call functions that expect the returned drm_display_mode to be destroyed eventually. However, none of the tests called drm_mode_destroy, which results in a memory leak. Since drm_mode_destroy takes two pointers as argument, we can't use a kunit wrapper. Let's just create a helper every test suite can use.
