mptscsih_qcmd(9)

🌸 NAME 🌸

mptscsih_qcmd — Primary Fusion MPT SCSI initiator IO start routine. 💖 Bestie, welcome to the mptscsih_qcmd(9) page in the Kernel API Manual. This is literally the main-character entry point for SCSI IO. No cap.

✨ SYNOPSIS ✨

enum scsi_qc_status mptscsih_qcmd (struct scsi_cmnd *SCpnt );

🎀 ARGUMENTS 🎀

• SCpnt — Pointer to scsi_cmnd structure. That's the lil request struct, and yes it's a pointer. 🫶

🦋 DESCRIPTION 🦋

Okay so first thing: this is the linux scsi_host_template.queuecommand routine — yes, that exact vibe. It's the primary SCSI IO start routine. 💅

What it does is create a MPI SCSIIORequest from a linux scsi_cmnd request and send it to the IOC. Like, request goes in, MPI SCSIIORequest comes out, IOC gets it. Iconic. ✨

It returns 0. (the rtn value is discarded by the linux scsi mid-layer — so that return is lowkey just there for the plot 😭).
