mpi3mr_bsg_populate_adpinfo(9)

💅 mpi3mr_bsg_populate_adpinfo — a Kernel API Manual moment (section 9, bestie)

okay so this one is from the Kernel API Manual, section 9, and it's literally the glow-up guide for mpi3mr_bsg_populate_adpinfo. she's a handler. she gets adapter info. she's booked and busy ✨

---

🌸 NAME 🌸

mpi3mr_bsg_populate_adpinfo — the Get adapter info command handler, no cap. that's her whole job description and she ate 💅

---

✨ SYNOPSIS ✨

long mpi3mr_bsg_populate_adpinfo (struct mpi3mr_ioc *mrioc , struct bsg_job *job );

like, yes, she returns a long. main character energy honestly 👑

---

🫶 ARGUMENTS 🫶

• mrioc — your adapter instance reference, aka the whole vibe of the controller you're asking about 🦋
• job — the BSG job reference, aka the little envelope this request slid into 💌

---

💖 DESCRIPTION 💖

so what does she do. she provides adapter information for the given controller. that's it, that's the tea 🍓 you hand her the adapter ref and the job, and she comes back with the info about that controller. lowkey iconic, highkey useful.

---

🔥 RETURN 🔥

• 0 on success — slay, we love a clean zero 🎀
• proper error codes on failure — so if it goes sideways you're getting a real error code back, not a mysterious vibe 💀

bestie this is a kernel function, so treat the adapter like you'd treat your fave — carefully 🫶 no guessing at behaviour, just call it right.

okay that's the whole page!! 📚✨ this cutie came from ./drivers/scsi/mpi3mr and the date on it is October 2026 (yes, future-dated, she's ahead of the timeline 💀🦋), and the page itself is mpi3mr_bsg_populate_adpinfo(9) in case you forgot already. mwah, go read the source, ily, bye 💜🎀
