pmcraid_sdev_init(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

okay bestie, welcome to pmcraid_sdev_init(9) from the Kernel API Manual — yes, that manual, and yes, this is the page.

pmcraid_sdev_init — literally the function that prepares for commands to a device. no cap, that's the whole vibe 💅

🌸 SYNOPSIS 🌸

int pmcraid_sdev_init (struct scsi_device *scsi_dev );

🎀 ARGUMENTS 🎀

  • scsi_dev — the scsi device struct. that's the one thing you pass in, and it's giving main character energy 🫶

💖 DESCRIPTION 💖

okay so picture this: the mid-layer is about to send a command to a brand-new device, and it calls pmcraid_sdev_init first. the function's whole job is to store the device's resource entry details inside the scsi_device struct. then Queuecommand comes through and uses that resource handle — plus the other details — to fill up IOARCB while sending commands to the device. iconic behavior, honestly ✨

Return value: 0 on success / -ENXIO if the device does not exist. that's the whole check, bestie 💅

🦋 SEE ALSO 🦋

bestie, the kernel file ./drivers/scsi/pmcraid.c is the home base for this whole saga, and here's the full see-also squad — every single one, no skips, no cap:

mwah 💋 — this page is from the source ./drivers/scsi, dated October 2026, and it's the pmcraid_sdev_init(9) page. bye bestie, go init some sdevs 🫶✨
