dm_test_get_funcs_nv(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_get_funcs_nv(9) — from the Kernel API Manual, bestie

okay so. this page is literally a kernel API manual entry, section 9, and it's about dm_test_get_funcs_nv. yes the name is a mouthful, no we are not abbreviating it. let's go ✨

✨ NAME ✨

dm_test_get_funcs_nv — Test Navi PP SMU function table setup 🎀

like that's the whole vibe. it's a test. about a function table. for Navi. we move.

🦋 SYNOPSIS 🦋

void dm_test_get_funcs_nv (struct kunit *test );

that's it. that's the signature. copy it exactly, don't get cute with the spacing, the spacing is load-bearing (it is not, but respect it anyway 💜).

🌸 ARGUMENTS 🌸

  • test — the KUnit test context. that's it. that's the whole argument list. one (1) parameter and she ate 👑

🔥 DESCRIPTION 🔥

so what does this actually do. ok so basically: this test verifies that DCN 2.0 initializes the Navi SMU function table — and then it also verifies that the unsupported PME workaround callback is left unset. 😭

like the whole point is that it gets set up correctly and that the thing that should NOT be set stays not-set. double check, double slay. no cap, that's the entire test.

fr fr, "unsupported" here is the point, not a bug — the test is literally checking that the callback stays unset. don't come for her 💅

👑 SEE ALSO 👑

okay this next part is long. like long long. but every single one of these is a real reference and we are not skipping a single one, because skipping is not the vibe. grab a snack bestie 🍓

see. we made it. 87 references and not a single one dropped 💖

and that's the page!! 🎀✨ super proud of you for making it to the bottom of that SEE ALSO list, genuinely. anyway this whole thing ships from ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — so yeah, mark your calendar, bestie, that's the version stamp for dm_test_get_funcs_nv(9). iykyk 🦋💜
