hw_protection_trigger(9)

💖 hw_protection_trigger(9) — the kernel API manual, bestie edition 💖

okay so real talk, this is a page from the Kernel API Manual and it's about the function that saves your hardware from literally melting down. no cap. let's get into it 🫶

✨ NAME ✨

hw_protection_trigger — Trigger default emergency system hardware protection action 🌸

🎀 SYNOPSIS 🎀

void hw_protection_trigger (const char *reason , int ms_until_forced );

🦋 ARGUMENTS 🦋

• reason — the reason for the emergency shutdown or reboot, bestie. it's a const char * and it gets printed. so write something iconic, not just "oops" 💅
• ms_until_forced — how long to wait for an orderly shutdown or reboot before triggering it. an int, so you got options. a negative value disables the forced shutdown or reboot entirely — like, no forcing, we're just chillin' 🙈

🔥 DESCRIPTION 🔥

Initiate an emergency system shutdown or reboot to protect hardware from further damage. yeah. literally the "your fave is in danger, we gotta shut this down" function 😭

the way that it works: the exact action taken is controllable at runtime — so it's not locked in, you can vibe-check it live — and it defaults to shutdown. periodt. 💀

🚨 real talk: this is emergency-protection territory, so like, don't call it for funsies. it's giving "hardware is about to have a bad time" energy.
