ata_bmdma_error_handler(9)

okay so welcome to ata_bmdma_error_handler(9), the page from the Kernel API Manual — yes, that manual. 💅

✨ NAME ✨

ata_bmdma_error_handler — Stock error handler for BMDMA controller. That's the whole vibe, bestie. 🫶

🌸 SYNOPSIS 🌸

void ata_bmdma_error_handler (struct ata_port *ap );

🎀 ARGUMENTS 🎀

• ap — the port to handle error for. That's it, that's the argument. 💖

🦋 DESCRIPTION 🦋

Stock error handler for BMDMA controller. It can handle both PATA and SATA controllers. Most BMDMA controllers should be able to use this EH as-is or with some added handling before and after. No cap, it's giving flexible-error-handler realness. ✨

LOCKING: Kernel thread context (may sleep) — so yes, sleeping is literally allowed here. 😴💅
