mpt_do_ioc_recovery(9)

💅 mpt_do_ioc_recovery — Kernel API Manual, section 9 🎀

okay so bestie, gather round, because this one is from the Kernel API Manual (that's section 9 of the manual, iykyk) and it's literally the glow-up routine for your MPT adapter ✨

---

🌸 NAME 🌸

mpt_do_ioc_recovery — the function that initializes or recovers your MPT adapter. no cap, that's the whole vibe: wake it up or bring it back from the brink 💖

---

🦋 SYNOPSIS 🦋

int mpt_do_ioc_recovery (MPT_ADAPTER *ioc , u32 reason , int sleepFlag
);

---

✨ ARGUMENTS ✨

• ioc — a pointer to the MPT adapter structure. this is your main character fr, everything happens to it 🫶
• reason — the event word / reason. like, why are we doing this, bestie 💭
• sleepFlag — if it's CAN_SLEEP, we use schedule; otherwise we use udelay. pick your coping mechanism 😴

---

💜 DESCRIPTION 💜

So this routine does all the steps necessary to bring the IOC to a OPERATIONAL state. like, every single one. the whole getting-ready-with-me montage 🔥

It also pre-fetches the LAN MAC address of a Fibre Channel MPT adapter. little bonus fetch, we love a multitasker 🎀

---

👑 RETURN 👑

the return values, and you will be memorizing these, bestie:

• 0 — success, slay ✨
• -1 — failed to get board READY 😭
• -2 — READY but IOCFacts Failed 💀
• -3 — READY but PrimeIOCFifos Failed 🙈
• -4 — READY but IOCInit Failed 😬
• -5 — failed to enable_device and/or request_selected_regions
• -6 — failed to upload firmware 🫠

heads up: READY is doing a lot of heavy lifting in this list. the board came up, but the next step fumbled. rude but valid.
