drm/tests: Add test for drm_framebuffer_init()

2024-09-11T12:17:10+00:00

Add three KUnit test cases for the drm_framebuffer_init function:

1. Test if expected values are being set after drm_framebuffer_init() call.
2. Try to init a framebuffer without setting its format.
3. Try calling drm_framebuffer_init() with mismatch of the drm_device
   passed at the first argument and the one pointed by fb->dev.

drm/tests: Add test for drm_framebuffer_lookup()

2024-09-11T12:17:10+00:00

Add two KUnit test cases for the drm_framebuffer_lookup function, one
for the base case, that tests if the lookup finds the correct framebuffer
object and another that tests the lookup for an inexistent framebuffer.

drm/tests: Add test case for drm_internal_framebuffer_create()

2024-09-11T12:17:08+00:00

drm/tests: Replace strcpy to strscpy on drm_test_framebuffer_create test

2024-09-11T12:17:07+00:00

Replace the use of strcpy to strscpy on the test_to_desc of the
drm_test_framebuffer_create test for better security and reliability.

drm/tests: Add parameters to the drm_test_framebuffer_create test

2024-09-11T12:17:07+00:00

Extend the existing test case to cover:
1. Invalid flag atribute in the struct drm_mode_fb_cmd2.
2. Pixel format which requires non-linear modifier with
DRM_FORMAT_MOD_LINEAR set.
3. Buffer offset for inexistent plane

drm/tests: Stop using deprecated dev_private member on drm_framebuffer tests

2024-09-11T12:16:59+00:00

The dev_private member of drm_device is deprecated and its use should
be avoided. Stop using it by embedding the drm_device onto a mock struct.

The new mock struct allows to share variables and even further mocks
over the tests in a cleaner way than using dev_private void pointer.

Also start using drm_kunit_helper_alloc_drm_device() for allocating
the drm_device mock.
