AMDGPIO(4)

💅 AMDGPIO(4) — like, the AMD GPIO Controller, bestie

okay so this is from the Kernel Interfaces Manual, and it's literally all about amdgpio — the AMD GPIO Controller driver. buckle up, it's short but it's iconic 🎀

✨ NAME ✨

amdgpio — the AMD GPIO Controller. that's it, that's the vibe. 🦋

🌸 SYNOPSIS 🌸

amdgpio* at acpi?
gpio* at gpiobus?

translation: it hangs off acpi, and it gives you a gpio buddy on gpiobus. attacher energy fr fr ✨

💖 DESCRIPTION 💖

so amdgpio provides a gpio(4) interface, and it does that for these AMD chipsets — literally just these two, no cap:

AMD Ryzen 7 5800U with Radeon Graphics
AMD Ryzen 7 8840HS with Radeon 780M Graphics

and bestie, it supports these pin configuration flags 👇

GPIO_PIN_INPUT
GPIO_PIN_OUTPUT
GPIO_PIN_INOUT
GPIO_PIN_ININ
GPIO_PIN_PULLUP
GPIO_PIN_PULLDOWN

and it's got interrupt capabilities too, which is giving main character energy 🔥

GPIO_INTR_POS_EDGE
GPIO_INTR_NEG_EDGE
GPIO_INTR_DOUBLE_EDGE
GPIO_INTR_HIGH_LEVEL
GPIO_INTR_LOW_LEVEL

iykyk — those are the exact flag names, so pls don't go renaming them, they're literal strings and i'm obsessed with them staying that way 💀

🦋 HISTORY 🦋

the amdgpio driver first appeared in NetBSD 11.0. era-defining, honestly 👑

🌈 AUTHORS 🌈

the amdgpio driver is derived from qcomgpio(4) and OpenBSD's amdgpio(4) — so it's got lore, we love a crossover 🌸

the man page was written by Ryo ONODERA ⟨ryoon@NetBSD.org⟩ — ty for your service, king 🫡

and that's the whole page, bestie!! this one shipped on the Debian side with a February 3, 2025 date stamp, so yeah — that's the version you're holding in your hands rn 💅✨🍓
