drm/dp_mst: Fix fractional DSC bpp handling

2024-01-25T23:44:57Z

[ Upstream commit 7707dd6022593f3edd8e182e7935870cf326f874 ] The current code does '(bpp << 4) / 16' in the MST PBN calculation, but that is just the same as 'bpp' so the DSC codepath achieves absolutely nothing. Fix it up so that the fractional part of the bpp value is actually used instead of truncated away. 64*1006 has enough zero lsbs that we can just shift that down in the dividend and thus still manage to stick to a 32bit divisor. And while touching this, let's just make the whole thing more straightforward by making the passed in bpp value .4 binary fixed point always, instead of having to pass in different things based on whether DSC is enabled or not. v2: - Fix DSC kunit test cases.

drm/tests: Fix kunit_release_action ctx argument

2023-09-30T15:13:05Z

The kunit_action_platform_driver_unregister is added with &fake_platform_driver as ctx, but the kunit_release_action is called pdev as ctx. Fix that by replacing it with &fake_platform_driver.

drm/tests: Fix incorrect argument in drm_test_mm_insert_range

2023-09-15T14:39:48Z

While drm_mm test was converted form igt selftest to kunit, unexpected value of "end" argument equal "start" was introduced to one of calls to a function that executes the drm_test_mm_insert_range for specific start/end pair of arguments. As a consequence, DRM_MM_BUG_ON(end <= start) is triggered. Fix it by restoring the original value.

drm/tests: Zero initialize fourccs_out

2023-09-08T20:38:19Z

fourccs_out array is not initialized. As the drm_fb_build_fourcc_list() doesn't necessarily change all the array, and the test compares all of it, the comparison could fail if the array is not initialized. Zero initialize the array to fix this.
