💖 handle_fasteoi_ack_irq(9) 💖

okay so this page is straight out of the Kernel API Manual, and it's giving "tiny but crucial interrupt-handler lore" energy. let's go, bestie 🫶✨

🌸 NAME 🌸

handle_fasteoi_ack_irq — irq handler for edge hierarchy stacked on transparent controllers. that's the name, that's the vibe check, periodt 💅

✨ SYNOPSIS ✨

void handle_fasteoi_ack_irq (struct irq_desc *desc );

that's the signature exactly as written, no edits, no cap 🎀

🦋 ARGUMENTS 🦋

• desc — the interrupt description structure for this irq. that's literally the one argument, bestie 🫶

🔥 DESCRIPTION 🔥

It's like handle_fasteoi_irq, but for use with hierarchy where the irq_chip also needs to have its ->irq_ack function called. that's the whole tea, fr fr ☕✨
