dm_test_find...ips_null_ptr(9)
π NAME π
okay so bestie, welcome to dm_test_find_first_crtc_skips_null_ptr β and yeah, that's a lot of a name, but the Kernel API Manual (section 9, the whole "kernel API" vibe, you know the one) has it right there in lights, so we're gonna say it with our whole chest:
dm_test_find_first_crtc_skips_null_ptr β it's the test that checks find_first_crtc skips empty connector slots. That's the whole flex. It's giving "I go first, but only if you're actually real" energy. π
No cap, that's it, that's the function's entire personality.
β¨ SYNOPSIS β¨
void dm_test_find_first_crtc_skips_null_ptr (struct kunit *test );
literally copy-pasted exactly like that, spaces and all, don't @ me π β the void return goes crazy (it returns nothing, it just is).
π ARGUMENTS π
testβ the KUnit test context. this is the little β¨situationβ¨ the test runs inside. give it to the function, it does its thing, nobody returns anything. periodt. π«Ά
π¦ SEE ALSO π¦
okay so buckle up bestie because this list is Iconic in the "there are SO many of us" sense β the whole test family shows up to the group chat. also go look at the kernel file itself, it's right here, no gatekeeping:

ok genuinely the way this list just keeps going?? 238 icons and every single one of them ate. iykyk π
and that's the whole page bestie, hope it slayed πΈ
cute little sign-off so you know where this came from: the source line is ./drivers/gpu/drm/amd/display/... and the date on it is October 2026 β so yeah, this whole manpage is from the future, which honestly tracks for how forward-thinking these tests are. ππβ¨
