💅 mpi3mr_cfg_g...nclosure_pg0(9) 💅

okay bestie, so this is a page from the Kernel API Manual and the star of the show is mpi3mr_cfg_get_enclosure_pg0 — say that five times fast, i can't either 💀. she's a little config-page reader with a big heart, and no cap, you're gonna want to know her.

---

✨ NAME ✨

mpi3mr_cfg_get_enclosure_pg0 — read the current Enclosure page0 🎀

---

🌸 SYNOPSIS 🌸

int mpi3mr_cfg_get_enclosure_pg0 (struct mpi3mr_ioc *mrioc , u16
*ioc_status , struct mpi3_enclosure_page0 *encl_pg0 , u16 pg_sz , u32
form , u32 form_spec );

---

🦋 ARGUMENTS 🦋

• mrioc — the adapter instance reference, aka your main character. give her the respect she deserves 🫶
• ioc_status — a pointer where the ioc status gets handed back to you. she's the receipts, keep her safe 💖
• encl_pg0 — pointer to where the Enclosure page 0 gets returned. yep, the whole point of the function, iconic behavior ✨
• pg_sz — size of the memory you allocated for the page pointer. don't lowball it 🙈
• form — the form used for addressing the page. it's giving "choose your fighter" 🌈
• form_spec — form-specific info, like the device handle. the little details, iykyk 💅

---

🧚 DESCRIPTION 🧚

so this is the handler for a config page read for a specific Enclosure page0 — literally her whole job and she ate 🔥

the ioc_status carries the controller-returned ioc_status. and here's the important part bestie, listen up 👑: this routine does NOT check ioc_status to decide whether the page read succeeded or not. that check is the caller's responsibility — so if you're the caller, the vibes check is on you, not her 💀

---

⭐ RETURN ⭐

0 on success, non-zero on failure. short and sweet, periodt 🎀

lowkey a reminder bestie: the page-read success check is yours to do. she hands you the ioc_status and trusts you with it. no cap 💀

and that's the whole page!! shipped from ./drivers/scsi/mpi3mr, dated October 2026 — catch you in the next manpage, mwah 💖🎀✨
