pl061_irq_ack(9)

✨ pl061_irq_ack ✨

okay bestie, so this is a page from the Kernel API Manual and it's literally all about one lil' function that handles interrupts. it's giving "small but mighty" energy tbh 💅

---

✨ NAME ✨

pl061_irq_ack — ACK an edge IRQ

like, it acknowledges an edge interrupt. that's the whole vibe. 🎀

---

✨ SYNOPSIS ✨

void pl061_irq_ack (struct irq_data *d );

---

✨ ARGUMENTS ✨

• d — the IRQ data for this IRQ. it's the main character of this function ngl 👑

---

✨ DESCRIPTION ✨

so here's the tea ☕: this function gets called from the edge IRQ handler to ACK the edge IRQ in the GPIOIC (interrupt-clear) register. periodt. 💖

and for level IRQs? bestie, this is not needed — they just go away when the level signal goes away. no cap, they literally handle themselves. 🙈✨

---

✨ SEE ALSO ✨

• Kernel file ./drivers/gpio/gpio-pl061.c — go read it if you wanna see the whole picture, iykyk 🦋

---

okay that's the whole page, you ate that 💅 remember: edge IRQs need the ACK, level IRQs are independent icons who don't need your help 🌸
