mpi3mr_scmd_from_host_tag(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

mpi3mr_scmd_from_host_tag — bestie, this is literally your get the SCSI command from the host tag hookup 💅

So this is a Linux kernel API manual page (section 9, the kernel API one, iykyk), all about mpi3mr_scmd_from_host_tag.

✨ SYNOPSIS ✨

struct scsi_cmnd * mpi3mr_scmd_from_host_tag (struct mpi3mr_ioc *mrioc ,
u16 host_tag , u16 qidx );

Like, that's the whole call. You give it stuff, it gives you back a struct scsi_cmnd *. Slay.

🫶 ARGUMENTS 🫶

Ok so here's the lineup of things you're handing over:

  • mrioc — the adapter instance reference 🎀 your controller's whole identity, basically.
  • host_tag — the host tag. Yes queen, that's the actual name, we keep it.
  • qidx — operational queue index. So, which queue we're talking about 🌈

💜 DESCRIPTION 💜

So the vibes here are: this function does the ✨math✨ of turning a host_tag plus a qidx into the block tag, then goes and retrieves the associated SCSI command for you — using scsi_host_find_tag. That's it, that's the whole plot 🦋

No cap, that's literally all it says.

🔥 RETURN 🔥

A SCSI command reference — or NULL 😭 so like, check it before you use it, bestie, fr fr.

👑 SEE ALSO 👑

The receipts start with the kernel file it lives in 💀:

  • ./drivers/scsi/mpi3mr/mpi3mr_os.c

And then the entire extended friend group — the whole crew, no one left out:

🧚 Sign-off 🧚

That's the whole page, bestie — it ships out of the kernel tree at ./drivers/scsi/mpi3mr and it's dated October 2026 ⭐ so it's giving slightly futuristic, we love that for us. Go forth and find those tags 💖🎀🦋
