dm_test_ato...o_state_bits(9)

✨ NAME ✨

dm_test_atomic_lut3d_nonzero_state_bits — okay so this is a KUnit test, and the whole vibe is: non-zero size means the state bits and the mode flags better be set 💅 no cap.

This page lives in the Kernel API Manual bestie, and the page name is dm_test_ato...o_state_bits(9) — yes it's abbreviated, that's just how the header rolls around here 🎀

🌸 SYNOPSIS 🌸

void dm_test_atomic_lut3d_nonzero_state_bits (struct kunit *test );

🎀 ARGUMENTS 🎀

• test — the KUnit test context. That's it, that's the whole arg list 🫶 it's literally just the test context being handed over so the test can do its thing.

💀 that's the whole page bestie — it's a short one, not every manpage is a novel. Go read the source file if you want the lore.

Sign-off szn 🧚 — this lil page came from ./drivers/gpu/drm/amd/display/... (yes, truncated like that, iconic), dated October 2026, and it answers to the name dm_test_ato...o_state_bits(9). Take care of her 💖🌸
