mpi3mr_get_all_tgt_info(9)

✨ mpi3mr_get_all_tgt_info(9) ✨

okay so this is a page from the Kernel API Manual and bestie, it's literally about mpi3mr_get_all_tgt_info — the function that tells userspace everything about the targets a controller is managing. let's get into it 💅

---

🌸 NAME 🌸

mpi3mr_get_all_tgt_info — Get all target information 🎯

---

🦋 SYNOPSIS 🦋

long mpi3mr_get_all_tgt_info (struct mpi3mr_ioc *mrioc , struct bsg_job
*job );

---

🎀 ARGUMENTS 🎀

• mrioc — the adapter instance reference, aka your controller's whole vibe and identity 🫶
• job — the BSG job reference, aka the request that's asking for the tea ☕

---

💖 DESCRIPTION 💖

so what does it actually do? this function copies the driver-managed target devices' device handle, persistent ID, bus ID and target ID into the user-provided buffer — and it does that for the specific controller you point it at. no cap, that's the whole errand 🧚

and like, that's not even all of it — this function also hands back the number of devices managed by the driver for that specific controller. it's giving "here's everyone plus a headcount" main character energy 👑

---

⭐ RETURN ⭐

0 on success, and proper error codes on failure. that's it, that's the deal 🙈
