megasas_ioc_init_fusion(9)

💅 megasas_ioc_init_fusion 💅

okay bestie, so this is a page from the Kernel API Manual — yes, the actual kernel docs, we're fancy now — and it's all about one lil function that does one big job. Let's get into it 🫶

---

✨ NAME ✨

megasas_ioc_init_fusion — Initializes the FW 💖

that's it. that's the whole job. it wakes the firmware up. iconic behavior honestly 👑

---

🦋 SYNOPSIS 🦋

int megasas_ioc_init_fusion (struct megasas_instance *instance );

so it takes one arg and hands you back an int. no cap, that's the whole signature 🎀

---

🌸 ARGUMENTS 🌸

• instance — the Adapter soft state. like, the whole soft-state vibe of the adapter. she carries the context, you just gotta hand her over 🧚

---

💜 DESCRIPTION 💜

Issues the IOC Init cmd ✨

that's the tea fr fr — this function fires off the IOC Init command. the FW gets its initialization moment. main character energy for the firmware, lowkey 🔥

ngl this one's short and sweet — but short does not mean skippable. if you're poking at fusion adapter init, this is literally the entry point 🌈

mwah 💋 this lil page lives in ./drivers/scsi/megaraid, and it's stamped October 2026 — so yes, she's fresh, she's dated, she's documented. slay, periodt, bye bestie 🦋✨🎀
