mvumi_handshake(9)

💅 mvumi_handshake(9) — like, the kernel API manual, bestie

okay so real talk, this page lives in the Kernel API Manual and it's all about mvumi_handshake, which is genuinely the "hey FW, wake up and get READY" function 🫶

✨ NAME ✨

mvumi_handshake — Move the FW to READY state

that's it, that's the whole mission. slay 💅

---

🦋 SYNOPSIS 🦋

int mvumi_handshake (struct mvumi_hba *mhba );

like yes, it returns an int, and yes, it takes exactly one (1) argument. no cap.

---

🎀 ARGUMENTS 🎀

• mhba — the Adapter soft state 💖 that's the whole thing, bestie, just the adapter's soft state getting handed over.

---

🌸 DESCRIPTION 🌸

okay so picture this: during the initialization, the FW passes can potentially be in any one of several possible states. literally any of them. it's giving chaos, it's giving main character energy 🌀

so here's the vibe check: if the FW is in one of those operational, waiting-for-handshake states, the driver must take steps to bring it to ready state. like, non-negotiable, driver's job, no excuses ✨

otherwise — meaning it's not in one of those states — it has to wait for the ready state. that's it. that's the rule. patience is a virtue, iykyk 🧚
