💅 mpt3sas_config_get_expander_pg0 — obtain expander page 0

okay so bestie, welcome to the Kernel API Manual ✨ — section 9 of the Kernel API Manual, to be exact — and today's main character is mpt3sas_con...expander_pg0(9), aka mpt3sas_config_get_expander_pg0. yes the name is long. yes it ate. 🎀

---

🌸 NAME 🌸

mpt3sas_config_get_expander_pg0 — obtain expander page 0

like, it goes and gets you an expander page 0. that's the whole vibe. no cap. 🦋

---

✨ SYNOPSIS ✨

int mpt3sas_config_get_expander_pg0 (struct MPT3SAS_ADAPTER *ioc ,
Mpi2ConfigReply_t *mpi_reply , Mpi2ExpanderPage0_t *config_page , u32
form , u32 handle );

it's giving "five arguments, all of them matter", and honestly? iconic. 💅

---

💖 ARGUMENTS 💖

• ioc — per adapter object. the whole adapter's like, personality file, yk? 🔥
• mpi_reply — reply mf payload returned from firmware. the firmware claps back and this is where it lands 😭
• config_page — contents of the config page. the actual tea. the goods. 🍓
• form — GET_NEXT_HANDLE or HANDLE. pick your fighter, literally, you have to pick one. 👑
• handle — expander handle. it's the expander's little name tag 🏷️

---

🧚 CONTEXT 🧚

sleep.

yes that's it. that's the whole note. it sleeps. put it to bed, let it nap, don't you dare call it from somewhere spicy 💀 like, respect the nap.

---

🌈 RETURN 🌈

0 for success, non-zero for failure. that's the binary of it all — either she slayed or she didn't 🫶

ngl if you're looking for the source of truth, she lives in ./drivers/scsi/mpt3sas — that's the directory, periodt. 👑

and that's the page, bestie — ./drivers/scsi/mpt3sas, October 2026, Kernel API Manual, section 9. go get that expander page 0 and slay 💅✨
