📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_atom...3d_zero_size(9) — from the Kernel API Manual ✨

okay bestie, gather round, because this one is a KUnit test entry and it's honestly kind of a vibe 🎀 It's the page for dm_test_atom...3d_zero_size in the Kernel API Manual, and the whole point is: zero LUT size, meaning the initialized flag must get cleared and no LUT data gets written. That's it, that's the girl. No cap. 💖

✨ NAME ✨

dm_test_atomic_lut3d_zero_size — Zero LUT size: initialized must be cleared, no LUT data written 🌸

Like, literally the entire personality of this test in one line: hand it a zero-size LUT and it's gonna check that the initialized state got cleared out and that not a single byte of LUT data was written. Iconic behavior, honestly. 💅

🦋 SYNOPSIS 🦋

void dm_test_atomic_lut3d_zero_size (struct kunit *test );

that's the whole signature, bestie — void return, one argument, done. clean. slay. ✨

🎀 ARGUMENTS 🎀

  • test — the KUnit test context 🧚 this is the little context object the test framework hands you so the test knows where it lives. that's the whole argument list, she's low-maintenance fr fr.

👑 SEE ALSO 👑

okay so this is the part where the manpage goes absolutely feral and shouts out the entire friend group 😭 like, every single related page, no one left behind, periodt. Here they all are:

the kernel file:

  • ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_color_test.c 💜

the whole squad of (9) pages:

like… that's the group chat, that's everybody 😭 every name spelled exactly right, no edits, no mergers, we do not touch the (9) section numbers, we respect the lore. 🫶

ngl bestie, if you're poking at AMD display color management tests, this is your girl — but the whole family is up there in SEE ALSO, so you've got options. go read the neighbors, iykyk 💀

and that's the page! 🍓 this lil cutie came out of ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — mwah, thanks for reading, love u, bye! 🌈💖✨
