💅 dm_test_dmub...load_timeout(9) — Kernel API Manual 🎀

okay so bestie, you're in the Kernel API Manual and the page you want is this one, dm_test_dmub_hw_init_auto_load_timeout(9). it's a KUnit test page, it's short, it's sweet, and it's giving "small but mighty" energy. let's go ✨

🌸 NAME 🌸

dm_test_dmub_hw_init_auto_load_timeout — literally just a test that proves hw init is fine with an auto-load timeout 🫶

⭐ SYNOPSIS ⭐

void dm_test_dmub_hw_init_auto_load_timeout (struct kunit *test );

💜 ARGUMENTS 💜

  • test — the KUnit test context, aka the lil' bundle of test state that gets handed to you. that's it, that's the whole argument 🙈

🔥 DESCRIPTION 🔥

okay so picture this: the DMUB firmware never reports ready. like, ever. so dmub_srv_wait_for_auto_load hits its timeout and gives up — timeout vibes, we hate to see it 😭

and here's the slay part: dm_dmub_hw_init doesn't crash, doesn't bail, doesn't even get dramatic. it just warns and still completes successfully. no cap. that's the whole thing this test is checking — that the warning-only behavior holds it down 💅
