🌸 dm_mst_test_aux_transfer_error_result — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a KUnit test page for the AMD display MST test crew and honestly it's giving "small function, big responsibilities" energy. let's get into it 🎀

✨ NAME ✨

dm_mst_test_aux_transfer_error_result — transfer errors are remapped. that's it, that's the whole vibe 💅

🦋 SYNOPSIS 🦋

void dm_mst_test_aux_transfer_error_result (struct kunit *test );

returns nothing, takes one thing. iconique of her honestly ✨

🌸 ARGUMENTS 🌸

  • test — the KUnit test context 🧚 that's the little test-world bubble she lives inside, fr fr.

💜 DESCRIPTION 💜

okay so picture this: a DC link service hands back a negative result 😭 (not a slay moment). that negative result needs to get converted — pushed through dm_dp_aux_transfer_result — using the AUX operation result that got returned. so basically: bad result comes in, gets remapped into the proper AUX-shaped outcome, and the test is checking the remap actually happened the way it should 🔥

it's a glow-up for error codes, lowkey. a ✨transformation arc✨. no cap.

ngl the whole point here is the remapping — transfer errors don't just stay transfer errors, they get translated. periodt 💅
