m68k_setup_irq_controller(9)

okay so bestie, this is m68k_setup_irq_controller(9) from the Kernel API Manual — the m68k interrupt-controller setup function — and we’re gonna read it together like a very focused group chat 💖

✨ NAME ✨

m68k_setup_irq_controller — that’s the name, with the lil dash and everything 💅

🎀 SYNOPSIS 🎀

void m68k_setup_irq_controller (struct irq_chip *chip ,
irq_flow_handler_t handle , unsigned int irq , unsigned int cnt );

🌸 ARGUMENTS 🌸

• chip — the irq chip that controls the specified irq 👑
• handle — the flow handler that handles the specified irq ✨
• irq — the first irq to be managed by the controller 🎀
• cnt — the number of irqs to be managed by the controller 🦋

🦋 DESCRIPTION 🦋

So what this does is change the controller for the specified range of irq — that controller is the one that’s gonna manage these irq, periodt. 💅

Here’s the tea: auto/user irq already have a default controller, and yes, that default controller can be changed as well. But heads up, bestie — the controller probably should use m68k_irq_startup/m68k_irq_shutdown. 🫶
