pm8001_mpi_reg_resp(9)

✨ NAME ✨

pm8001_mpi_reg_resp — process register device ID response. that's the whole name section bestie, but stay for the lore 🫶

hey bestie, welcome to the pm8001_mpi_reg_resp(9) page from the Kernel API Manual. it's giving kernel-level main character energy, and we're gonna make it make sense 💅

---

🌸 SYNOPSIS 🌸

okay so the signature is literally this, no cap:

int pm8001_mpi_reg_resp (struct pm8001_hba_info *pm8001_ha , void *piomb
);

---

🦋 ARGUMENTS 🦋

• pm8001_ha — our hba card information. yep, the HBA card info we're working with 💖
• piomb — IO message buffer. the buffer carrying the IO message 💌

---

💅 DESCRIPTION 💅

okay so picture this: the sas layer finds a device and it notifies LLDD. then the driver registers the domain device to FW. this event is the return device ID which the FW has assigned. from now on, inter-communication with FW is no longer using the SAS address — nope, it uses the device ID which FW assigned. periodt. 👑
