okay so bestie, welcome to the Kernel API Manual π
you're looking at dm_test_nv_g..._clocks_fail(9) β yeah the title got truncated, she's dramatic like that β but the real full name is right down there in NAME, no cap.
πΈ NAME πΈ
dm_test_nv_get_max_sustainable_clocks_fail β Test generic error π«Ά
like, that's literally her whole job. she tests a generic error. iconic behavior honestly.
π SYNOPSIS π
void dm_test_nv_get_max_sustainable_clocks_fail (struct kunit *test );
yes that's the whole signature, she's a void, she gives nothing back, she just does the thing π
π¦ ARGUMENTS π¦
testβ the KUnit test context β¨ that's your lil test-world-in-a-box, everything she needs to know about the test run lives in there.
π DESCRIPTION π
okay so the vibe check here is simple and honestly kind of slay: this test verifies that pp_nv_get_maximum_sustainable_clocks returns PP_SMU_RESULT_FAIL. that's it. that's the whole plot. she's making sure the failure path actually fails the way it's supposed to, and if it doesn't? π test's cooked.
periodt. π₯

that's the whole group chat, everybody accounted for π§π
well bestie, that's the page π source is ./drivers/gpu/drm/amd/display/... and the date on this bad girl is October 2026, still calling herself dm_test_nv_g..._clocks_fail(9) at the bottom because she refuses to change her display name π slay, honestly. go forth and fail gracefully π€β¨
