mpi3mr_reinit_ioc(9)

💅 mpi3mr_reinit_ioc — Kernel API Manual ✨

okay so bestie, welcome to mpi3mr_reinit_ioc(9), the lil glow-up routine for your controller 🫶

---

✨ NAME ✨

mpi3mr_reinit_ioc — re-initialize the controller 💫

---

🌸 SYNOPSIS 🌸

int mpi3mr_reinit_ioc (struct mpi3mr_ioc *mrioc , u8 is_resume );

---

🎀 ARGUMENTS 🎀

• mrioc — your adapter instance reference, the main character of this whole operation 👑
• is_resume — tells you whether we got called from the resume path or the reset path 🦋

---

💖 DESCRIPTION 💖

This is the controller re-initialization routine, and she is booked and busy 😭 She gets executed from the soft reset handler or from the resume callback — so yeah, she shows up for both gigs.

Here's the itinerary, no cap:

• creates operational reply queue pairs 🔥
• allocates the required memory for the reply pool 🍓
• allocates the required memory for the sense buffer pool 🌸
• issues the IOC init request to the firmware ⭐
• unmasks the events 🌈
• issues port enable to discover SAS/SATA/NVMe devices and RAID volumes 👑

like… she literally does everything. it's giving "I'll handle it" energy 💅

---

🌼 RETURN 🌼

0 on success, and non-zero on failure. that's it, that's the vibe check 💀

okay that's the whole page bestie, go re-init something 💜 she comes from the source tree at ./drivers/scsi/mpi3mr, dated October 2026, and she's filed under mpi3mr_reinit_ioc(9) — mwah 💋🌸
