📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_get...t_empty_list(9) — like, the whole page, bestie

okay so real talk, this one lives in the Kernel API Manual and the page header up top literally reads dm_test_get...t_empty_list(9) (yes it's abbreviated, that's just how the header prints it — the actual function below has its full government name, don't come for me 🫶).

This page is describing a KUnit test: checking what happens when you look up a CRTC on an empty CRTC list. That's it. That's the vibe check. ✨

🌸 NAME 🌸

dm_test_get_crtc_by_otg_inst_empty_list — a test for CRTC lookup on an empty CRTC list. Empty list in, lookup happens, that's the whole plot 😭

🎀 SYNOPSIS 🎀

void dm_test_get_crtc_by_otg_inst_empty_list (struct kunit *test );

✨ ARGUMENTS ✨

  • test — the KUnit test context. It's giving "the little bag of test stuff the harness hands you" 💜

🦋 SEE ALSO 🦋

Kernel file — the source lives here, obsessed with this path honestly:

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

and here's the full friend group, no one left out, not a single one 💖:

ngl bestie the entire "test" here is the empty list case — no CRTCs, go look one up anyway, and see what you get back. That's the whole assignment. Iconic, honestly 💅

sign-off szn 🎀 this little page comes to you from ./drivers/gpu/drm/amd/display/... (the source line is abbreviated exactly like that, and yes the footer says the same thing — we stan a consistent queen 👑) and it's dated October 2026, footer and all, dm_test_get...t_empty_list(9) to the very end. bye bestie, go read the source, it ate 💖✨🦋
