scsi_report_bus_reset(9)

📦 version 7.3.1, in nixpkgs unstable

okay so welcome to the scsi_report_bus_reset(9) page from the Kernel API Manual 💖 this one is short, sweet, and very “tell the host what just happened” — let’s get into it ✨

💖 NAME 💖

scsi_report_bus_reset — report bus reset observed 🫶

✨ SYNOPSIS ✨

void scsi_report_bus_reset (struct Scsi_Host *shost , int channel );

🎀 ARGUMENTS 🎀

  • shost — Host in question 👑
  • channel — channel on which reset was observed. 👀

🌸 DESCRIPTION 🌸

It’s a utility function used by low-level drivers to report that they have observed a bus reset on the bus being handled. literally just “hey bestie, a bus reset happened over here” energy 💅

🔒 Lock status: Host lock must be held. no cap, this is important — hold that Host lock.

🔥 RETURN 🔥

Nothing. that’s it, void vibes 💀

🌼 NOTES 🌼

This only needs to be called if the reset is one which originates from an unknown location. Resets originated by the mid-level itself don’t need to call this, but there should be no harm.

The main purpose of this is to make sure that a CHECK_CONDITION is properly treated. so yes, it’s lowkey doing important cleanup work ✨
