💅 NCR5380_maybe_reset_bus(9) 💅

okay bestie, welcome to the Kernel API Manual page for NCR5380_maybe_reset_bus(9) — the function that detects and corrects bus wedge problems. It’s giving “SCSI bus first aid” energy, and honestly? iconic. 🩹✨

🌸 NAME 🌸

NCR5380_maybe_reset_bus — Detect and correct bus wedge problems. 🛠️💖

✨ SYNOPSIS ✨

int NCR5380_maybe_reset_bus (struct Scsi_Host *instance );

🎀 ARGUMENTS 🎀

• instance — the adapter to check. 🫶

🌈 DESCRIPTION 🌈

So picture this: the system crashed, and it may have crashed with a connected target and the SCSI bus busy. 😭 First move? Check for BUS FREE phase. If it’s not free, try to abort the currently established nexus — which we know nothing about, btw. If that also fails, do a bus reset.

🚨 Note that a bus reset will cause the chip to assert IRQ.

Returns 0 if successful, otherwise -ENXIO. Slay. 💅
