[PATCH RESEND v3 0/2] Add KUnit tests for drm_fb_blit()

[PATCH RESEND v3 0/2] Add KUnit tests for drm_fb_blit()

[Arthur Grillo]

This patchset tests the drm_fb_blit() function.

As this function can be used with already tested formats, the first
patch adds calls to drm_fb_blit() on the tests of supported formats.

Some supported formats were not yet covered by the existing tests
because they are only supported by drm_fb_blit(). The second patch
adds those format conversion tests.

Changes in v3:
- Fix memset sizes to avoid out-of-bound access
- Link to v2: https://lore.kernel.org/r/20230905-final-gsoc-v2-0-b52e8cb068ea@riseup.net

Changes in v2:
- Split the patch into two (Maíra Canal)
- Link to v1: https://lore.kernel.org/r/20230901-final-gsoc-v1-1-e310c7685982@riseup.net

[PATCH RESEND v3 2/2] drm/tests: Add new format conversion tests to better cover drm_fb_blit()

[Arthur Grillo]

To fully cover drm_fb_blit(), add format conversion tests that are only
supported through drm_fb_blit().
