💅 ata_sff_port_intr — Kernel API Manual energy 💅

✨ NAME ✨

okay so bestie, this page is ata_sff_port_intr — Handle SFF port interrupt. That's the name, and that's the whole assignment. The manual is the Kernel API Manual, folded in right here instead of copying the header line. periodt. 💖

🌸 SYNOPSIS 🌸

Here's the signature, exactly as it appears — don't let the line break scare you, it's just chillin':

unsigned int ata_sff_port_intr (struct ata_port *ap , struct
       ata_queued_cmd *qc );

🎀 ARGUMENTS 🎀

  • ap — Port on which interrupt arrived (possibly...). The mysterious lil (possibly...) is literally part of the original, so we keep it, bestie. 🫶
  • qc — Taskfile currently active in engine.

💅 DESCRIPTION 💅

Handle port interrupt for given queued command. That's it. That's the mission. 🔥

LOCKING: spin_lock_irqsave(host lock)

Locking note is right there in the original, and we are not skipping it. Keep the vibe locked and loaded. 🔒

🌈 RETURN 🌈

One if interrupt was handled, zero if not (shared irq).

So: One = handled, zero = not, and the (shared irq) caveat is part of the package. Don't skip it, fr fr. 🫶

🦋 SEE ALSO 🦋

okay so this SEE ALSO list is huge and honestly iconic. Kernel file first:

  • Kernel file: ./drivers/ata/libata-sff.c

Then the whole squad, every single reference, no cap:
