💅 dm_test_ato...g_crtc_state(9) 💅

okay so this one is straight out of the Kernel API Manual — yes, the truncated title is literally what the page calls itself, iykyk 😭 the full name is right below tho, don't panic.

✨ NAME ✨

dm_test_atomic_check_missing_crtc_state — the vibe check that confirms a missing CRTC state actually fails 💀

🌸 SYNOPSIS 🌸

void dm_test_atomic_check_missing_crtc_state (struct kunit *test );

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. that's the whole thing, bestie, it's giving minimal ✨

🦋 DESCRIPTION 🦋

so what this test does: it verifies that atomic_check rejects a plane with DC state when the atomic CRTC state is absent. like, no CRTC state? not today. it should fail, and this test makes sure it does 🫶

fr fr — the absence of the CRTC state is the whole point. the rejection is the expected, correct behaviour here, not a bug 🙈

👑 SEE ALSO 👑

and now the main character energy: the entire friend group 💖 the kernel file lives at ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_plane_test.c and here's every single sibling, no cap:

that's the whole guest list, ate and left no crumbs 💅✨

and the cute lil sign-off: this page comes from the file path ./drivers/gpu/drm/amd/display/... (yes it's cut off, the manpage said so, not me 😭), dated October 2026, and it's page dm_test_ato...g_crtc_state(9) in the Kernel API Manual. mwah 🫶🎀🌸
