[PATCH v2 00/11] Increase coverage on drm_framebuffer.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patchset includes new KUnit tests for 7 untested functions from
drm_framebuffer.c and improvements to the existent one.

The first patch replace the use of dev_private member from drm_device
mock on the existent test by embedding it into an outer struct containing
a generic pointer.

The patches 2 and 4 extends the test of drm_internal_framebuffer_create()
by creating a new test case and adding new parameters to the existent case.

The patch 3 just replace a strcpy() call to strscpy().

Finally, the remainder of this set contains 7 new test cases, one for each
of the follow functions:

- drm_framebuffer_check_src_coords()
- drm_framebuffer_cleanup()
- drm_framebuffer_lookup()
- drm_framebuffer_init()
- drm_framebuffer_free()
- drm_mode_addfb2()
- drm_fb_release()

v2:
  - Split strcpy to strscpy change on drm_test_framebuffer_create test
  into a separate patch [PATCH 03/11].
  - Extensively use drm_kunit_helper_alloc_drm_device() for drm_device mock.
  - Reorder kunit cases alphabetically.
  - Rename check_src_coords_case.
  - Remove unnecessary comments.
  - Add framebuffer size as a parameter on drm_framebuffer_check_src_coords
  case.
  - Replace drm_mode_object_add() call to drm_framebuffer_init() on
  drm_framebuffer_lookup() test.
  - Let fb1.dev unset instead of set it to wrong_drm to test mismatched
  drm_device passed as drm_framebuffer_init() argument on
  drm_framebuffer_init() test.
  - Clean the framebuffer object on drm_framebuffer_init_test.
