💅 mpc52xx_init_irq — the Kernel API Manual, bestie edition 🎀

okay so literally welcome to the mpc52xx_init_irq(9) page from the Kernel API Manual — yes that's the manual name, and yes it's a whole vibe ✨

✨ NAME ✨

mpc52xx_init_irq — initialize and register with the virq subsystem 🦋

🌸 SYNOPSIS 🌸

void mpc52xx_init_irq (void );

💖 ARGUMENTS 💖

• void — no arguments, bestie. literally none. not a single one. it's giving self-sufficient queen energy 👑

🔥 DESCRIPTION 🔥

So this function is the hook for setting up IRQs on an mpc5200 system. A pointer to this function is to be put into the machine definition structure — like, that's its whole job in the seating chart, iykyk 🫶

What it actually does, fr fr:

• searches the device tree for an MPC5200 interrupt controller 🔍
• initializes it 🌱
• registers it with the virq subsystem 🎀

That's the whole glow-up. search, init, register. periodt 💅

not me being obsessed with a function that has zero arguments and still does three things — main character energy ngl 😭
