dm_test_nv_...y_count_fail(9)

✨ NAME ✨

okay so the page header is dm_test_nv_...y_count_fail(9), and this whole thing lives in the Kernel API Manual — yes bestie, we're in kernel API manual territory. The actual function is dm_test_nv_set_display_count_fail, and it's here to test generic error mapping.

🎀 SYNOPSIS 🎀

void dm_test_nv_set_display_count_fail (struct kunit *test );

💅 ARGUMENTS 💅

• test — the KUnit test context, aka the little test vibe container.

🦋 DESCRIPTION 🦋

The mission is simple and iconic: verify that pp_nv_set_display_count returns PP_SMU_RESULT_FAIL on a generic DPM error. That's the whole plot, no cap.

k bye bestie, this page signs off from source/version ./drivers/gpu/drm/amd/display/... with the date October 2026, and the footer tag is still dm_test_nv_...y_count_fail(9) 💖✨
