💅 DEFINE_INTERRUPT_HANDLER_NMI — Kernel API Manual ✨

okay bestie, buckle up, we're talking about DEFINE_INTERRUPT_HANDLER_NMI today, from the Kernel API Manual — yes that one, the powerpc interrupt-handler family, and this one is the NMI one. NMI = non-maskable interrupt, aka the interrupt that does NOT take no for an answer. icon behavior honestly. 👑

🌸 NAME 🌸

DEFINE_INTERRUPT_HANDLER_NMI — literally "Define NMI interrupt handler function", that's the whole vibe, that's the assignment, we ate. 💅

like, that's it. that's the whole call. she's concise. 🦋

✨ ARGUMENTS ✨

🔥 RETURN 🔥

Returns a value back to the asm caller. yes, the assembly caller is the one receiving it — no cap, it goes straight back to asm. 📬

💖 DESCRIPTION 💖

the macro is written so it acts as a function definition — it's giving "I'm a macro but I'm cosplaying a function" and honestly? slayed. 👑

⚠️ important, bestie: you Append the body with a pair of curly brackets. like the definition isn't done until you give her her braces. don't forget the { }. that's not optional, that's just how she works. 😭
