dm_test_crtc_set_vupdate_irq_no_otg β NAME β¨
okay so bestie, welcome to the Kernel API Manual entry for dm_test_crtc_set_vupdate_irq_no_otg β say that five times fast, i dare you π β and what it does is literally Test vupdate irq with unassigned OTG. that's the whole vibe. no cap.
πΈ SYNOPSIS π
void dm_test_crtc_set_vupdate_irq_no_otg (struct kunit *test );
that's it. that's the signature. she's short, she's sweet, she's an icon π
π¦ ARGUMENTS π
testβ the KUnit test context π§ that's the little bundle of test-y goodness this function gets handed, periodt.
π DESCRIPTION β
so here's the tea β β when the CRTC has no OTG instance assigned, like when otg_inst == -1, the function must return 0 immediately. like, instantly. no detours, no side quests π«Ά
and it must do that without touching the DC interrupt state β not even a little. not a poke, not a prod, nothing π so basically the whole entire point of this test is checking that the early-return gate is gating, and that nothing downstream gets its grubby little hands on the DC interrupt state. slay π₯
π SEE ALSO π
bestie, buckle up, this list is long β she's giving main character energy and also an entire test suite. every single one of these, no skips:

ngl bestie, that's the whole page π no hidden sections, no surprise flags, no environment variables β she's a tiny little KUnit test and she knows exactly what she is. iykyk π§
and that's a wrap, babe π«Ά this lil gem lives over at ./drivers/gpu/drm/amd/display/... in the Kernel API Manual, dated October 2026 β mwah, go write some tests, you're gonna ate π
