💅 NAME

okay so bestie, gather round — this one is dm_test_set_vline0_irq_state_no_crtc and it is literally the "Test vline0 irq state with missing CRTC" test ✨

🔥 THE KERNEL FILE

no cap, if you wanna read the actual source (and honestly? you should, she's right there), it lives here:

./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_irq_test.c

that's the Kernel file reference, keep it close 🧚

💖 friendly reminder that all of the above is Kernel API documentation — (9) means section 9 of the manual, i.e. kernel routines. iykyk.

🌈 and that's the whole page, bestie, we ate and left absolutely zero crumbs 👑
