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

okay so picture this: you're in the DRM/AMD display layer, you've got an aux command, and you need it to go out through the dmub via an inbox message. that's the whole gig. this function also sets the port index appropriately for legacy DDC — like, it knows what to do with the old-school stuff 🎀
