mpt3sas_con...s_iounit_pg1(9)

💅 NAME 💅

okay besties, gather round — this page is from the Kernel API Manual and it's all about mpt3sas_config_get_sas_iounit_pg1 — literally just obtain sas iounit page 1. that's the whole vibe. she fetches, she returns, she slays. 🦋

---

✨ SYNOPSIS ✨

int mpt3sas_config_get_sas_iounit_pg1 (struct MPT3SAS_ADAPTER *ioc ,
Mpi2ConfigReply_t *mpi_reply , Mpi2SasIOUnitPage1_t *config_page , u16
sz );

like look at her signature. four whole arguments. main character energy fr fr 👑

---

🎀 ARGUMENTS 🎀

• ioc — the per adapter object, aka the hardware's whole personality 💖
• mpi_reply — the reply mf payload that comes back from firmware (yes, "mf" as in the actual original wording, we respect the lore) ✨
• config_page — the contents of the config page. this is the tea she's serving 🍵
• sz — the size of the buffer you passed in config_page. don't lie about it bestie, she needs the real number 💀

---

🌸 CONTEXT 🌸

sleep.

that's it. that's the context. she naps. 😴 not me being jealous of a kernel function's work-life balance—

---

🫶 DESCRIPTION 🫶

okay so here's the thing, and this is lowkey important: the calling function should call config_get_number_hba_phys prior to this function. no cap. the reason is so that enough memory is allocated for config_page. skip that step and you're gonna have a bad time, and not in a fun way 😭

like it's giving "read the instructions before you assemble the furniture." do it in order. periodt.

---

⭐ RETURN ⭐

• 0 for success 🎉
• non-zero for failure 🙈

binary queen. no in-between, no situationship, just zero or not-zero.

like?? fifty-eight references?? she's connected. she knows everybody. iykyk 🌈

ngl this whole page lives under ./drivers/scsi/mpt3sas, dated October 2026, and the page itself answers to mpt3sas_con...s_iounit_pg1(9) (yes it's abbreviated in the header, we don't question her choices 💜).

okay that's the page!! go forth, allocate your memory first, and stan a config function that respects its own nap schedule 🧚‍♀️💖
