zynq_gpio_get_value(9)

📦 version 7.3.1, in nixpkgs unstable

💅 zynq_gpio_get_value(9) — from the Kernel API Manual ✨

okay so bestie, gather round, because today we're reading a single pin's whole vibe 🎀 and yes, this is a real kernel function, and yes, it's in the Kernel API Manual, so you KNOW it's official 👑

✨ NAME ✨

zynq_gpio_get_value — literally just: get the state of the specified pin of a GPIO device 🦋 no cap, that's the whole job. She reads the pin, she tells you what it's giving. iconic behavior, honestly 💅

🌸 SYNOPSIS 🌸

int zynq_gpio_get_value (struct gpio_chip *chip , unsigned int pin );

that's it. two arguments, one int coming back at you. lowkey the most chill signature ever 😌

🫶 ARGUMENTS 🫶

  • chip — the gpio_chip instance you're working on, aka the one getting the attention rn. main character energy only 💖
  • pin — the gpio pin number within the device. not global, bestie, within the device — iykyk 🌈

🧚 DESCRIPTION 🧚

so, like, what does she actually DO? this function reads the state of the specified pin of the GPIO device. that's the tea. that's the entire plot 🍓

you hand her a chip and a pin number, she comes back with the state. no drama, no side quests, just a clean little read. obsessed honestly ✨

⭐ RETURN ⭐

  • 0 → the pin is low 💀
  • 1 → the pin is high 🔥

that's it. zero or one. binary queen behavior 👑 no other values, no in-between, no "it depends" — she is NOT that kind of function 🙈

🔮 SEE ALSO 🔮

okay this is the friend group, and they're all in the kernel file ./drivers/gpio/gpio-zynq.c — go say hi to all of them 💜

ngl bestie, gpio_data_ro_bug(9) is right there in the list and the name alone is giving "we know, we know" 😭 read it if you're curious, but that's a you-and-the-manpage moment 🎀

and that's the whole page, periodt 💅 this one lives under ./drivers/gpio, dated October 2026, straight from the Kernel API Manual — mwah, go read your pins, bestie 🫶✨🌸
