mpi3mr_update_tgtdev(9)

💅 mpi3mr_update_tgtdev(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a little kernel function from the mpi3mr driver and honestly it's giving "quiet little worker bee that keeps the whole device list from falling apart" 🐝💖

---

🌸 NAME 🌸

mpi3mr_update_tgtdev — the DevStatusChange evt bottomhalf, no cap 💫

---

🎀 SYNOPSIS 🎀

void mpi3mr_update_tgtdev (struct mpi3mr_ioc *mrioc , struct
       mpi3mr_tgt_dev *tgtdev , struct mpi3_device_page0 *dev_pg0 , bool
       is_added );

that's the whole signature bb, copy it exactly, do not touch a single character 🫶

---

✨ ARGUMENTS ✨

• mrioc — the adapter instance reference 💜 aka "which controller are we even talking about"
• tgtdev — the target device's internal structure — the driver's own lil home for that device 🏠
• dev_pg0 — the new device page0 📄 (fresh out of firmware, still warm)
• is_added — a flag that tells you the device was just added 🆕 like, brand new, first day energy

---

🌈 DESCRIPTION 🌈

So what this icon actually does 👑: it takes all the info from device page0 and updates it into the driver's cached target device structure 💾✨

Everything the driver remembers about that device? Yeah. It gets refreshed from page0 and lives in the cached struct. Lowkey essential glue work, highkey slay 🧚

---

💀 RETURN 💀

Nothing. That's it. It returns void, bestie — no value, no drama, no return-code to check 🙈 (so don't go doing if (mpi3mr_update_tgtdev(...)) because there is literally nothing to compare, ok?) 😭

anyway that's the page!! this lil beauty ships out of ./drivers/scsi/mpi3mr and it's dated October 2026 🌸 so yeah, from the future, obviously 💅 go forth and update those cached target devices bestie, mwah 🫶✨🎀
