gpiochip_generic_config(9)
π¦ gpiochip_generic_config(9) β like, the Kernel API Manual page, bestie π
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 β¨
β¨ NAME β¨
gpiochip_generic_config β apply configuration for a pin π
πΈ SYNOPSIS πΈ
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 π«Ά
π ARGUMENTS π
gcβ the gpiochip that owns the GPIO. it's giving main character energy, because everything here belongs to it πoffsetβ the offset of the GPIO you're applying the configuration to, i.e. which pin on that chip we're talking about πconfigβ the configuration to be applied. the actual payload, the moment, the whole point π
π₯ RETURN π₯
0 on success, or a negative errno on failure. that's it. that's the return. slay π
ngl, always check the return β a negative errno is the kernel's way of saying "not today" π
π SEE ALSO π
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 π go read them, iykyk π§
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 π
