2025-04-25drm/tests: helpers: Create kunit helper to destroy a drm_display_modeMaxime Ripard1-0/+22
[ Upstream commit 13c1d5f3a7fa7b55a26e73bb9e95342374a489b2 ] A number of test suites call functions that expect the returned drm_display_mode to be destroyed eventually. However, none of the tests called drm_mode_destroy, which results in a memory leak. Since drm_mode_destroy takes two pointers as argument, we can't use a kunit wrapper. Let's just create a helper every test suite can use.

2024-01-26drm/dp_mst: Fix fractional DSC bpp handlingVille Syrjälä1-3/+3
[ 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.

2023-03-29drm: test: Fix 32-bit issue in drm_buddy_testDavid Gow1-1/+2
The drm_buddy_test KUnit tests verify that returned blocks have sizes which are powers of two using is_power_of_2(). However, is_power_of_2() operations on a 'long', but the block size is a u64. So on systems where long is 32-bit, this can sometimes fail even on correctly sized blocks. This only reproduces randomly, as the parameters passed to the buddy allocator in this test are random. The seed 0xb2e06022 reproduced it fine here. For now, just hardcode an is_power_of_2() implementation using x & (x - 1).
