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

2025-08-28T14:34:43+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.

[ Upstream commit d28b9d2925b4f773adb21b1fc20260ddc370fb13 ]

When compiling with sparse enabled, this warning is thrown:

  warning: incorrect type in argument 2 (different base types)
     expected restricted __le32 const [usertype] *buf
     got unsigned int [usertype] *[assigned] buf

Add a cast to fix it.

drm/tests: shmem: Fix memleak

2025-04-29T15:28:28+00:00

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: probe-helper: Fix drm_display_mode memory leak

2025-04-08T15:28:25+00:00

drm_analog_tv_mode() and its variants return a drm_display_mode that

which leads to a memory leak.
