gpiochip_generic_config(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ¦‹ gpiochip_generic_config(9) β€” like, the Kernel API Manual page, bestie πŸ’…

okay so picture this: you're deep in the kernel, you've got a GPIO chip in your hands, and you just need to slap some configuration onto one specific pin. that's THE vibe of gpiochip_generic_config. it's the generic config hookup, and it is lowkey iconic for it ✨


✨ NAME ✨

gpiochip_generic_config β€” apply configuration for a pin πŸŽ€

🌸 SYNOPSIS 🌸

int gpiochip_generic_config (struct gpio_chip *gc , unsigned int offset
, unsigned long config );

like yeah, that's the whole signature. three things in, one int out, no cap 🫢

πŸ’– ARGUMENTS πŸ’–

  • gc β€” the gpiochip that owns the GPIO. it's giving main character energy, because everything here belongs to it πŸ‘‘
  • offset β€” the offset of the GPIO you're applying the configuration to, i.e. which pin on that chip we're talking about πŸ“
  • config β€” the configuration to be applied. the actual payload, the moment, the whole point πŸ“

πŸ”₯ RETURN πŸ”₯

0 on success, or a negative errno on failure. that's it. that's the return. slay πŸ’€

ngl, always check the return β€” a negative errno is the kernel's way of saying "not today" 😭

🌈 SEE ALSO 🌈

okay bestie, buckle up, because this list is long and every single one of them is a real one. fr fr they all live in the Kernel file ./drivers/gpio/gpiolib.c:


like, that's an entire friend group of GPIO functions and they all ate πŸ’œ go read them, iykyk 🧚

and that's the page! brought to you from the ./drivers/gpio corner of the kernel, dated October 2026, answering to the name gpiochip_generic_config(9) β€” mwah, bye bestie, go configure some pins πŸ’…πŸŽ€β­
