💖 ata_bmdma_port_intr(9) 💖

okay so bestie, this is ata_bmdma_port_intr(9) straight out of your Kernel API Manual, and it's literally the little function that handles a BMDMA port interrupt for you 🦋 ngl it's short, it's sweet, it's giving "small but crucial" energy.

• ap — Port on which interrupt arrived (possibly...) 👀
• qc — Taskfile currently active in engine 🌸

---

✨ DESCRIPTION ✨

Handle port interrupt for given queued command. that's the whole vibe, she's focused 💅
