dm_test_nv_clock_id_phyclk(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

dm_test_nv_clock_id_phyclk — the little KUnit test that checks PHYCLK id mapping, and yes bestie it's a whole vibe. 💅

This one lives in the Kernel API Manual, so you already know it's head-empty-no-thoughts documentation for people who write kernel tests, iykyk. 🎀

✨ SYNOPSIS ✨

void dm_test_nv_clock_id_phyclk (struct kunit *test );

That's it. That's the whole signature. No cap. 🫶

💜 ARGUMENTS 💜

  • test — the KUnit test context, aka the little bag of test-runner state the framework hands you so your test can actually exist. That's the entire input. Give it what it wants and slay. ✨

🦋 DESCRIPTION 🦋

okay so here's the deal, bestie: this test verifies that PP_SMU_NV_PHYCLK maps to amd_pp_phy_clock, and that the whole thing returns true. 💖

That's the assignment. It understood the assignment. Literally one mapping, one boolean, one extremely focused little unit test. Not me being obsessed with how small and correct it is. 😭🔥

Heads up: the function takes test and returns void — the test passes or fails through KUnit, and what it's asserting is that mapping + true result. Nothing more, nothing invented. 🙈

and then the whole friend group — every single one of these, no skipping, periodt. 👑

that's the whole page, bestie — and before you close the tab, the ✨sign-off✨: this icon comes from ./drivers/gpu/drm/amd/display/... and it's dated October 2026. 🦋 screenshot it, cite it, live laugh love it. 💖🌟
