mpi3mr_bring_ioc_ready(9)

📦 version 7.3.1, in nixpkgs unstable

💅 mpi3mr_bring_ioc_ready — like, the Kernel API Manual's main character

okay so bestie, welcome to mpi3mr_bring_ioc_ready (that's a real function name from the Kernel API Manual, section 9, and no we're not abbreviating it, it's iconic) ✨

🌸 NAME 🌸

mpi3mr_bring_ioc_ready — bring the controller to ready state 🫶

🎀 SYNOPSIS 🎀

int mpi3mr_bring_ioc_ready (struct mpi3mr_ioc *mrioc );

no cap, that's the whole signature. short. sweet. slaying. 💅

🦋 ARGUMENTS 🦋

  • mrioc — the adapter instance reference 💖 that's your handle to the controller you're about to hype up. one argument, one vibe.

✨ DESCRIPTION ✨

so here's the tea 🍓: it sets the Enable IOC bit in the IOC configuration register, and then it waits — yes, waits — for the controller to become ready. it's giving "texting first and then waiting for the reply" energy 😭 but for hardware. literally the whole job. set the bit, wait for ready. periodt. 👑

🔥 RETURN 🔥

  • 0 on success 🎉 (the good ending, we love that for us)
  • appropriate error on failure 💀 (not every story has a happy ending, ngl)

🧚 SEE ALSO 🧚

bestie, buckle up, because the family tree is huge. the kernel file this lives in is ./drivers/scsi/mpi3mr/mpi3mr_fw.c 💜 and here's everyone else you might bump into:

like, that's the whole extended friend group 🫶 iykyk.

heads up bestie: a couple of names above are spelled exactly the way the manual spells them, so if something looks a lil sus, that's on purpose — copy it character for character, don't "fix" it 🙈
