2023-11-09drm/tests: Remove slow testsMaxime Ripard2-2369/+0
Both the drm_buddy and drm_mm tests have been converted from selftest to kunit recently. However, a significant portion of them are trying to exert some part of their API over a huge number of iterations and with random variations of their parameters. They are thus more a way to discover new bugs than actual unit tests. This is fine in itself but leads to very slow runtime (up to 25s for some drm_test_mm_reserve and drm_test_mm_insert on a Ryzen 7950x while running the tests in qemu) which make them a poor fit for kunit. Let's remove those tests from the drm_mm and drm_buddy test suites for now, and if it's ever needed we can always create proper unit tests for them later on. This made the entire DRM tests execution time (as of v6.6-rc1) come from 65s to less than .5s on a Ryzen 7950x system when running under qemu, and from 9 minutes to about 4s on a RaspberryPi4.

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).

This test case uses an arbitrary pitch size, different of the default one, to test if the conversions methods obey. Change the "destination_pitch" colors to change the monochrome expected result from being just zeros, as this makes the arbitrary pitch use unusable.

2023-03-10drm/format-helper: Make conversion_buf_size() support sub-byte pixel fmtsJavier Martinez Canillas1-2/+5
There are DRM fourcc formats that have pixels smaller than a byte, but the conversion_buf_size() function assumes that pixels are a multiple of bytes and use the struct drm_format_info .cpp field to calculate the dst_pitch. Instead, calculate it by using the bits per pixel (bpp) and divide it by 8 to account for formats that have sub-byte pixels.
