dm_test_nv_...in_uclk_fail(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

okay so bestie, first thing you need to know: the header on this page reads dm_test_nv_...in_uclk_fail(9) and that's not a typo, the man page tooling literally ran out of room and hit it with the ... 💀. The actual icon we're hyping up is dm_test_nv_set_hard_min_uclk_fail — she's a Kernel API Manual girlie and her whole job is testing generic error mapping. Yes, the name is doing the absolute most and yes, she ate. 💅

✨ SYNOPSIS ✨

void dm_test_nv_set_hard_min_uclk_fail (struct kunit *test );

that's it, that's the whole signature. one function, one argument, zero drama 🫶

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. it's the little vibe-passport that tells the test framework where it lives and how to report back. lowkey essential, don't lose it 🙈

💖 DESCRIPTION 💖

okay so here's the tea 🍓: this test verifies that pp_nv_set_hard_min_uclk_by_freq returns PP_SMU_RESULT_FAIL. That's the entire assignment. She calls the function, she checks that the result is the failure value, she reports back to KUnit. No cap, that's iconic behavior — a test that only exists to confirm the error path actually errors. the way that it literally just checks for a fail... obsessed. 👑

and that's the page!! 🌈 before you close the tab, the source is ./drivers/gpu/drm/amd/display/... and the date stamp says October 2026, which is wild but okay 😭 — mwah, go run your tests bestie, you're gonna slay 💖💅✨
