dm_test_fin...link_missing(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_fin...link_missing(9) — like, the Kernel API Manual page, bestie

okay so first things first: yes, the title is literally truncated with ... in the middle — that's not me being lazy, that's genuinely how this page is named, dm_test_fin...link_missing(9), section 9, straight out of the Kernel API Manual. we love a mysterious abbrev moment ✨

Also full disclosure: the last link of the title is link_missing, and the NAME below starts with find_stream_with_link_missing, so the full thing is deffo dm_test_find_stream_with_link_missing — the man page just chose to give us the cliffhanger version. iconic behavior tbh 🎀

🌸 NAME 🌸

dm_test_find_stream_with_link_missing — the test that checks what happens when you go looking for a stream and the link is, uh, missing 👀 literally what it says on the tin.

✨ SYNOPSIS ✨

void dm_test_find_stream_with_link_missing (struct kunit *test );

she takes one arg, she returns void, she does not elaborate 💅

🦋 ARGUMENTS 🦋

  • test — the KUnit test context 🧚 that's it, that's the whole vibe, it's the lil' test harness object you hand over.

🔥 SEE ALSO 🔥

okay bestie grab a snack because this list is long and we are not skipping a single one of them, no cap 🫶

Kernel file:

  • ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_backlight_test.c — the actual file where all this lives ✨

and the whole friend group (all section 9, all related):

like, that's the entire extended universe right there. a whole friend group of backlight tests 😭💜

quick vibe check: this page doesn't spell out the return value, the errors, or any options — because it genuinely doesn't have any. don't come for me, come for the source 🫶

okay and finally the sign-off bestie 🎀 — this page comes from the source path ./drivers/gpu/drm/amd/display/... and it's dated October 2026, closing out with dm_test_fin...link_missing(9). go off, spooky-season manpage, you ate 💅🔥👑
