mpt_do_upload(9)

💅 mpt_do_upload(9) — kernel API manual, but make it make sense 🫶

okay bestie, so this whole page is about mpt_do_upload from the mpt_do_upload(9) kernel API manual, and honestly? it's giving "small function, big consequences." let's get into it ✨

---

🌸 NAME 🌸

mpt_do_upload — literally just builds a FWUpload request and sends it off to an MPT adapter port. that's the whole vibe. construct + send, no cap 💌

---

🎀 SYNOPSIS 🎀

int mpt_do_upload (MPT_ADAPTER *ioc , int sleepFlag );

---

✨ ARGUMENTS ✨

• ioc — a pointer to the MPT_ADAPTER structure. it's the adapter in question, the main character of this whole operation 👑
• sleepFlag — tells you whether the process is allowed to sleep. that's it, that's the flag 😴

---

🦋 DESCRIPTION 🦋

so here's the tea: it returns 0 for success, >0 for a handshake failure, and <0 for a fw upload failure. the sign of the return value is literally the whole plot twist, so read it carefully 🔥

Remark: if the IOC is bound and a successful FWUpload was already performed on the bound IOC, then the second image is discarded and the memory is free'd. also — both channels must upload or the IOC ends up running in degraded mode. that part is not optional, bestie, it's not a suggestion 💀
