pcs_irq_init...ined_handler(9)

💖 pcs_irq_init_chained_handler(9) — from the Kernel API Manual, bestie 💖

Okay so like, literally the first thing you need to know is that this page's whole header is a little truncated mess — it shows up as pcs_irq_init...ined_handler(9) at the top of the page — but the actual function we're talking about is pcs_irq_init_chained_handler, and it lives in the Kernel API Manual. Don't let the squished header jump-scare you, it's giving "text got cut off in the group chat", that's all. 🎀
