💅 dm_test_upd..._non_dp_noop — Kernel API Manual ✨

okay so bestie, real talk: this one's from the Kernel API Manual and it's a KUnit test helper. Come sit with me, it's actually so straightforward you'll be obsessed.

🌸 NAME 🌸

dm_test_update_subconnector_non_dp_noop — literally just tests that a non-DisplayPort connector is left untouched (it's an early return, that's the whole gag, no notes 💅).

✨ SYNOPSIS ✨

void dm_test_update_subconnector_non_dp_noop (struct kunit *test );

that's it. that's the whole call. iconic behaviour honestly 🎀

🦋 ARGUMENTS 🦋

  • test — the KUnit test context. yeah, that's the only thing you gotta hand over, and it's just the test framework's little context blob so the test can do its thing. periodt 🫶

💜 SEE ALSO 💜

okay so here's where it gets long, bestie — the whole test family lives together in the kernel file ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_connector_test.c and honestly the whole squad gets listed. grab a snack, we're going through all of them 👑
