dm_test_appl...a_first_fail(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_appl...a_first_fail(9) — yeah that's the whole name babe

okay so bestie, this is a page from the Kernel API Manual and the function name is genuinely so long it got truncated in the header itself — the manpage literally gave up and wrote dm_test_appl...a_first_fail(9). iconic behavior honestly. the real name is dm_test_apply_synaptics_fifo_reset_wa_first_fail, and no I will not be shortening it, she earned every character. 🎀

✨ NAME ✨

dm_test_apply_synaptics_fifo_reset_wa_first_fail — Test FIFO reset early exit 🦋

like, that's it. that's the whole vibe. it's a test, and it's checking what happens when the FIFO reset thing bails out early. periodt.

🌸 SYNOPSIS 🌸

void dm_test_apply_synaptics_fifo_reset_wa_first_fail (struct kunit
*test );

so she takes exactly one thing and returns nothing (void, my beloved "I do things, I don't answer questions" return type). no cap.

💖 ARGUMENTS 💖

  • test — The KUnit test context. this is the lil test-framework baddie that gets passed in so the test knows what's up. she's the main character here fr fr. 👑

🔥 SEE ALSO 🔥

okay so this is the part where I need you to buckle in, because the SEE ALSO section on this page is enormous — it's giving "the whole friend group showed up to the party". every single one of these is a real sibling test living in the same kernel file, and every single one is listed here, in order, no skips, no edits. iykyk 💀

so first, the kernel file itself lives here:

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

and here is the entire crew, alphabetically-ish as the manpage gave them:

like… one hundred and forty-two siblings. she's not alone, she's got a whole ensemble cast. 🫶🌈

heads up bestie: this page tells you what the test is called and what context it takes — it doesn't hand you the source, so go read amdgpu_dm_helpers_test.c if you wanna see the actual body. that's the file listed above, go get it. 🧚

🎀 cute lil sign-off 🎀

this page came from the kernel docs source path ./drivers/gpu/drm/amd/display/... (yes, truncated just like the title — the manpage generator was feeling mysterious), dated October 2026, and it is officially dm_test_appl...a_first_fail(9). go forth and test that early exit, bestie. slay. 💜✨
