rtas_activate_firmware(9)

💖 NAME 💖

rtas_activate_firmware — Activate a new version of firmware. ✨

Okay bestie, welcome to the Kernel API Manual page for rtas_activate_firmware — it’s giving “tiny function, important firmware vibe,” no cap. 🫶

🌸 SYNOPSIS 🌸

void rtas_activate_firmware (void );

🎀 ARGUMENTS 🎀

• void — no arguments, bestie. Literally none. 🙈

🦋 CONTEXT 🦋

This function may sleep. 😴💤

👑 DESCRIPTION 👑

So here’s the tea: this function activates a new version of partition firmware. 🧚✨

The OS must call this after resuming from a partition hibernation or migration in order to maintain the ability to perform live firmware updates. That part is highkey important. 👑

And if this method is absent or if it fails? Not catastrophic — seriously — just log the condition in that case. 💖
