zynq_gpio_irqhandler(9)

💖 NAME 💖

zynq_gpio_irqhandler — IRQ handler for the gpio banks of a gpio device.

Okay bestie, welcome to the Kernel API Manual ✨ This page is all about zynq_gpio_irqhandler(9), and yes she is that girl. 💅

✨ SYNOPSIS ✨

void zynq_gpio_irqhandler (struct irq_desc *desc );

🌸 ARGUMENTS 🌸

• desc — the irq descriptor instance of the 'irq'.

🦋 DESCRIPTION 🦋

Okay so here's the tea, fr fr: this function reads the Interrupt Status Register of each bank to get the gpio pin number which has triggered an interrupt. Then it acks the triggered interrupt and calls the pin specific handler set by the higher layer application for that pin. Slay. 💖

🎀 NOTE 🎀

🚨 A bug is reported if no handler is set for the gpio pin. Not the vibe, bestie — keep that in mind. 😭
