✨ mpt3sas_config_get_pcie_iounit_pg1(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a lil function page from the mpt3sas family — yes, the same mpt3sas that lives in ./drivers/scsi/mpt3sas. Buckle up, it's short and sweet, my fave kind.

---

🌸 NAME 🌸

mpt3sas_config_get_pcie_iounit_pg1 — literally just: obtain pcie iounit page 1. that's it. that's the whole vibe. 🎀

---

🦋 SYNOPSIS 🦋

int mpt3sas_config_get_pcie_iounit_pg1 (struct MPT3SAS_ADAPTER *ioc ,
Mpi2ConfigReply_t *mpi_reply , Mpi26PCIeIOUnitPage1_t *config_page , u16
sz );

she returns an int, she takes four args, she's doing the absolute most with that signature ngl 💅

---

💜 ARGUMENTS 💜

• ioc — the per adapter object 🫶 this is your adapter's whole personality, basically.
• mpi_reply — reply mf payload returned from firmware ✨ the firmware's little answer-back moment.
• config_page — contents of the config page 🌸 this is where the good stuff lands.
• sz — size of buffer passed in config_page 📏 so she knows exactly how much room she's got, no cap.

---

⭐ CONTEXT ⭐

sleep. 😴

that's it, that's the context. she sleeps. respect her rest era fr fr.

---

🔥 DESCRIPTION 🔥

Returns 0 for success, non-zero for failure. iconic behavior honestly — zero means slay, anything else means we're not okay 😭
