mpi3mr_bsg_adp_reset(9)

💅 mpi3mr_bsg_adp_reset(9) 💅

okay so bestie, welcome to the kernel API manual — this one's a little function from the mpi3mr crew and honestly? it's giving "do one thing, do it correctly, then reboot the whole vibe." ✨

---

🌸 NAME 🌸

mpi3mr_bsg_adp_reset — issue a controller reset. yep. that's the whole job. no cap.

---

✨ SYNOPSIS ✨

long mpi3mr_bsg_adp_reset (struct mpi3mr_ioc *mrioc , struct bsg_job
*job );

two arguments, one long coming back at you. simple. iconic. periodt. 💅

---

🎀 ARGUMENTS 🎀

• mrioc — the adapter instance reference, aka "which controller are we talking about bestie" 🫶
• job — the BSG job reference. like, the request that rolled up to the door with a vibe. 💌

---

🦋 DESCRIPTION 🦋

so here's the tea: this function looks at the reset type that the user provided, then issues the appropriate reset to the controller. after that it waits for the whole thing to finish, reinitializes the controller, and then it returns. that's it. that's the whole plot. 🔥

(and yeah, the reset type comes from the user, so it's genuinely identifying what kind of reset you asked for before doing anything. main character energy from the adapter ngl.)

---

⭐ RETURN ⭐

0 on success 🎉 — and proper error codes on failure 😭. so like, check it. fr fr.

ngl the reset gets issued and we wait for it — so don't expect this to be instant, bestie. it's doing the full glow-up in sequence. 🙈

okay that's the page!! this one shipped out of ./drivers/scsi/mpi3mr back in October 2026, and the header's still repping mpi3mr_bsg_adp_reset(9) in the Kernel API Manual — so go forth, reset that controller, and slay 💅✨🎀🦋💖
