💾 mpt_downloadboot(9) 💾

okay so welcome to the Kernel API Manual, bestie — this page is mpt_downloadboot(9) and it's literally the girl who pushes firmware onto your MPT adapter. short page, but she matters. ✨

---

✨ NAME ✨

mpt_downloadboot — DownloadBoot code 🎀

---

🌸 SYNOPSIS 🌸

int mpt_downloadboot (MPT_ADAPTER *ioc , MpiFwHeader_t *pFwHeader , int sleepFlag );

---

🦋 ARGUMENTS 🦋

• ioc — a pointer to the MPT_ADAPTER structure, aka the whole adapter vibe. she needs this. 💅
• pFwHeader — a pointer to the firmware header info. this is the tea about the fw you're about to shove in. 🫶
• sleepFlag — tells us whether the process is allowed to sleep. yes, sleeping is permitted for some processes, iconic honestly 😴

---

👑 DESCRIPTION 👑

so FwDownloadBoot requires Programmed IO access — like, no cap, that's the whole prerequisite. 🔥

Now the return tea, and this part is important so pay attention bestie:

• Returns 0 for success 🎉
• -1 — FW Image size is 0
• -2 — No valid cached_fw Pointer
• <0 for fw upload failure 💀

fr fr, do a vibe check on those negatives before you assume anything went right. 🙈
