💖 mpt3sas_con...s_iounit_pg1(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for mpt3sas_config_set_sas_iounit_pg1, and yes the title is lowkey truncated with ... but that's just how it's filed, we don't fight the filename, we respect the filename 🫶

✨ NAME ✨

mpt3sas_config_set_sas_iounit_pg1 — send sas iounit page 1 💅

---

🌸 SYNOPSIS 🌸

int mpt3sas_config_set_sas_iounit_pg1 (struct MPT3SAS_ADAPTER *ioc ,
Mpi2ConfigReply_t *mpi_reply , Mpi2SasIOUnitPage1_t *config_page , u16
sz );

that's the whole signature, no cap, type it exactly like that 🔥

---

🎀 ARGUMENTS 🎀

• ioc — the per adapter object 🧚 this is your adapter's whole personality, basically.
• mpi_reply — the reply mf payload that gets returned from firmware 📨 like firmware slid into your DMs with an answer.
• config_page — the contents of the config page. this is the actual stuff, the payload, the main character 👑
• sz — the size of the buffer you passed in config_page. yes you gotta tell it how big your buffer is, it's not gonna guess 🙈

---

💜 CONTEXT 💜

sleep. 😴 that's it, that's the context. it sleeps.

---

🦋 DESCRIPTION 🦋

okay so here's the thing the calling function needs to do first: it should call config_get_number_hba_phys prior to this function, so that enough memory is allocated for config_page 💖 like, do the prep work first bestie, don't show up to the function with an undersized buffer, it's giving unprepared 😭

---

🌈 RETURN 🌈

• 0 — success, slay, we ate ✨
• non-zero — failure, we did not eat 💀

that's the whole page bestie, go forth and set that sas iounit page 1 🦋💖

ngl the vibe check is: prep with config_get_number_hba_phys first, or your config_page buffer is gonna have a bad time 😭
