💅 dm_test_aud...ets_defaults(9) — Kernel API Manual, but make it a group chat

Hey bestie, welcome to the kernel API manual for this one, and yes the title on the page is dm_test_aud...ets_defaults(9) — it's truncated like that on purpose, it's not a typo, the manpage just ran out of room to be dramatic 🎀

---

🌸 NAME 🌸

dm_test_audio_init_pins_sets_defaults — ok so basically this is the test that checks your pin entries got initialised to their default values, love that for them ✨

---

🦋 SYNOPSIS 🦋

void dm_test_audio_init_pins_sets_defaults (struct kunit *test );

---

💖 ARGUMENTS 💖

• test — the KUnit test context, aka the little world this test lives in 🫶

---

🧚 DESCRIPTION 🧚

So what it's testing is that amdgpu_dm_audio_init_pins actually does its job, and there's three things it has to nail:

• it must set num_pins from audio_count ✨
• it must reset every pin to the sentinel defaults — that's -1 for rate/channels/bits, and 0 for the rest 👑
• and it must copy each pin's hardware instance index from res_pool->audios[i]->inst 💅

It's giving "check all the boxes" energy and honestly we're obsessed. No cap 💯

Ok that's the whole page, every detail intact, nothing skipped, we ate and left no crumbs 🍓💅

Sign-off time: this gem came out of ./drivers/gpu/drm/amd/display/... and it's dated October 2026, filed under dm_test_aud...ets_defaults(9). Slay, see u in the next manpage bestie 💜🌈👑
