💖 dm_test_fill_audio_info_latency_present(9) 💖

okay so bestie, buckle in, because we're hanging out in the Kernel API Manual today and this page is genuinely so specific it's adorable. The function we're stanning is dm_test_fill_audio_info_latency_present — yes that's a whole mouthful, yes it's giving "my variable name ate and left no crumbs", and yes, it does exactly one tiny iconic thing: it tests the "Fill audio info latency present" situation. That's it. That's the whole vibe. 💅

🌸 NAME 🌸

dm_test_fill_audio_info_latency_present — the test for Fill audio info latency present. No cap, that's literally the description, straight from the source. 🫶

✨ SYNOPSIS ✨

void dm_test_fill_audio_info_latency_present (struct kunit *test );

Lowkey a one-liner, highkey perfect. Returns void, takes exactly one (1) argument, and honestly? She's low-maintenance. 🎀

🦋 ARGUMENTS 🦋

  • test — the KUnit test context 💜. That's the whole argument list. One (1) singular parameter. She doesn't need more, she's not greedy. Not me being obsessed with a function that has a single argument 😭

👑 SEE ALSO 👑

Okay so this is the part where the manpage goes full group-chat-adds-everyone energy, because there are a lot of siblings in this test family. Grab a snack. 🍓

The kernel file living at:

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

and then, in no particular order but very much in this particular order:

Twenty-six friends plus the file path. She travels with an entourage, fr fr. 🌈

ngl bestie, if you're looking for the other latency test — the "absent" one — she's right there in the list: dm_test_fill_audio_info_latency_absent_keeps_zero(9). This page is the "present" one. Don't mix them up, iykyk. 🙈

🧚 sign-off 🧚

This little love letter came from the kernel source path ./drivers/gpu/drm/amd/display/... and is dated October 2026 — yes, future energy, main character timeline — and the manual page itself is titled dm_test_fil...ency_present(9), abbreviated exactly like that because even manpage titles get tired. 💀

That's the whole page, bestie. Short, sweet, extremely void, and absolutely slaying in a KUnit kind of way. Go test those audio latency fields. 💖✨🎀
