zynq_gpio_irq_ack(9)

📦 version 7.3.1, in nixpkgs unstable

💅 zynq_gpio_irq_ack(9) — like, the Kernel API Manual, bestie ✨

okay so real talk, this page? it's from the Kernel API Manual, and it's all about one tiny lil function that does one tiny lil thing: acknowledging an interrupt on a gpio pin. that's it. that's the whole vibe. but ngl it's kind of a big deal in context, so let's get into it 🫶

🌸 NAME 🌸

zynq_gpio_irq_ack — acknowledge the interrupt of a gpio pin. yes literally, that's the job. she clocks in, she acks the irq, she leaves 💅

✨ SYNOPSIS ✨

void zynq_gpio_irq_ack (struct irq_data *irq_data );

like, that's the whole signature. void return — she gives nothing back, she's not here for your emotional validation, she just does the thing 🎀

🦋 ARGUMENTS 🦋

  • irq_data — irq data containing the irq number of the gpio pin for the interrupt you wanna ack. so it's carrying the receipts: which pin, which interrupt, all of it. you hand her this and she knows exactly what to acknowledge 💖

👑 DESCRIPTION 👑

so here's the tea 🔥 this function calculates the gpio pin number from the irq number, and then it sets the bit in the Interrupt Status Register of the corresponding bank — and that is how the irq gets ACKed. periodt.

basically: irq number goes in, math happens, the right bank's Interrupt Status Register gets its bit set, interrupt officially acknowledged. she ate and left no crumbs 🍓

🌈 SEE ALSO 🌈

okay this is the group chat of related functions and structs, and honestly the whole friend group is iconic:

lowkey a reminder: this page ships out of ./drivers/gpio, dated October 2026. so when you're citing it in your notes, that's the source and the date, no cap 🧚

and that's the whole page, bestie. go ack those interrupts. slay 💅✨🎀
