dm_test_veri...es_null_luts(9)
π NAME π
okay so bestie, this is dm_test_verify_lut_sizes_null_luts β and honestly the name is giving "I ate and left no crumbs" because it tells you the whole plot: both LUTs absent: must succeed. That's it. That's the vibe. No LUTs, no drama, the test still has to pass. periodt. β¨
(this page lives in the Kernel API Manual, section 9, just so you know where you are π«Ά)
πΈ SYNOPSIS πΈ
void dm_test_verify_lut_sizes_null_luts (struct kunit *test );
literally just one function, one argument, zero chaos π
π ARGUMENTS π
testβ the KUnit test context π that's the whole thing, she's the main character here, everything gets reported through her.

ok that's the whole squad and yes I listed every single one because we do NOT do "etc." in this house π
π alright bestie, that's the page!! source came from ./drivers/gpu/drm/amd/display/... and it's dated October 2026, so mark your calendar, and remember: when both LUTs are MIA, this test still has to slay. bye bestie, go read the kernel source, ily πππ¦
