📦 version 7.3.1, in nixpkgs unstable

👑 pm8001_ctl_mpi_interface_rev_show(9) 👑

okay so bestie, we're deep in the Kernel API Manual today — like, the actual Linux kernel docs, not a vibe. This one's a sysfs attribute reader for the pm8001 SCSI driver, and it's lowkey adorable how tiny it is. Let's get into it 💅

✨ NAME ✨

pm8001_ctl_mpi_interface_rev_show — literally just here to hand you the MPI interface revision number 🎀

✨ SYNOPSIS ✨

ssize_t pm8001_ctl_mpi_interface_rev_show (struct device *cdev , struct
device_attribute *attr , char *buf );

That's the whole signature, no cap. Three args, one return value, zero drama 🦋

✨ ARGUMENTS ✨

  • cdev — pointer to the embedded class device, aka the whole reason this function even knows what it's looking at 💖
  • attr — the device attribute. It's marked unused, so ngl it's just kinda standing there looking pretty 🙈
  • buf — the buffer that gets returned. This is where the goods go ✨

✨ DESCRIPTION ✨

So here's the tea: this is a sysfs 'read-only' shost attribute 🫶

That's it. That's the description. She's a show-er, not a teller — you read it, you don't write to it. Periodt 💅

✨ SEE ALSO ✨

The kernel file lives at:

./drivers/scsi/pm8001/pm8001_ctl.c

And because she rolls with a whole squad, here's the entire friend group 🎀:

ngl that's a long list but every single one of them is a real one, iykyk 🌸

And that's the whole page, bestie — short, sweet, and iconic 🌈

Sign-off szn 🫶: this gem lives under ./drivers/scsi/pm8001, dated October 2026, and it's serving Kernel API Manual energy from the pm8001_ctl_...ace_rev_show(9) era. Slay, go read your sysfs attributes responsibly 💜
