📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_read_vbios_edid_missing_callback — the Kernel API Manual page you didn't know you needed

okay so real talk, bestie: this is page dm_test_read...ing_callback(9) from the Kernel API Manual (yes the header truncates it like that, the full glow-up name is right down there in NAME, keep reading 🫶). It's a whole manual page for one KUnit test case, and honestly? iconic behavior. let's get into it ✨

🌸 NAME 🌸

dm_test_read_vbios_edid_missing_callback — Test missing callback skip

that's it. that's the whole vibe. it's a test, and what it's testing is the missing-callback skip path. slay 💅

🎀 SYNOPSIS 🎀

void dm_test_read_vbios_edid_missing_callback (struct kunit *test );

literally one function, takes one arg, returns void. no cap, no surprises, just a tidy little test entry point 😌

🦋 ARGUMENTS 🦋

  • test — The KUnit test context 💖 that's the KUnit scaffolding handin' you the test-context struct so the test can actually, y'know, do test things. main character energy only.

✨ SEE ALSO ✨

okay bestie buckle up, because the SEE ALSO on this page is enormous and I am not about to skip a single one of them, because every one of these little test icons deserves their moment 👑

first, where this lives:

  • Kernel file — ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_helpers_test.c

and now the full squad, in exactly the order the page gives them, no cuts, no edits, no "oh that one's boring" — all of them are invited to the group chat 🧚:

and that's the whole roster. 142 friends and not one of them left on read 💖

ngl that's a lot of cross-refs for one little missing-callback test, but we respect the hustle. iykyk.

👑 the sign-off 👑

this page comes to you from ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — so yeah, future-coded, ahead of the curve, as always 💅 go forth and skip that callback, bestie. slay 🦋✨🍓
