mpi3mr_bsg_pel_enable(9)

💅 mpi3mr_bsg_pel_enable — the PEL-enable handler bestie ✨

okay so real talk, this is a page from the Kernel API Manual, and it's about one very specific little function. buckle up, it's short but she's cute 🎀

---

🌸 NAME 🌸

mpi3mr_bsg_pel_enable — the handler for the PEL enable driver. that's literally her whole job. main character energy, no notes 👑

---

✨ SYNOPSIS ✨

long mpi3mr_bsg_pel_enable (struct mpi3mr_ioc *mrioc , struct bsg_job
*job );

she takes two things and she returns a long. that's it, that's the vibe 🦋

---

🫶 ARGUMENTS 🫶

• mrioc — your adapter instance reference, aka the whole controller baddie you're talking to 💜
• job — the BSG job pointer. yes, the job. she's pointing at it. respect her 🙈

---

💖 DESCRIPTION 💖

okay so this function is the handler for PEL enable driver — literally that's the whole thing, she's the handler ✨

what she does, in order, no skipping:

1. she validates the application given class and locale — like a little bouncer at the door, checking IDs 🎀
2. and if it's required, she aborts the existing PEL wait request — bye bestie 💀
3. and/or she issues a new PEL wait request to the firmware — hi new bestie 🌈
4. and then she returns 🫡

so it's giving "check the vibes, maybe clean up the old request, maybe post a fresh one, and dip" — and honestly? iconic 🌟

🔥 RETURN 🔥

• 0 on success 🎉
• proper error codes on failure 😭

that's the whole return situation, no cap.
