mv_sff_irq_clear(9)

✨ NAME ✨

okay so bestie, welcome to the mv_sff_irq_clear(9) page — yes, straight outta the Kernel API Manual, and it's giving “tiny function, big interrupt-clearing energy” 💅

mv_sff_irq_clear — clear the hardware interrupt after DMA. That's the whole vibe. 🫶

🌸 SYNOPSIS 🌸

void mv_sff_irq_clear (struct ata_port *ap );

🎀 ARGUMENTS 🎀

• ap — the port associated with this ATA transaction. That's your struct ata_port *, bestie. 🦋

🔥 DESCRIPTION 🔥

This one is only for ATAPI bmdma transactions, periodt. Otherwise, we experience spurious interrupts after libata-sff handles the bmdma interrupts 😭. So yeah — ATAPI bmdma transactions, this is your moment. ✨
