CHVGPIO(4)

💖 CHVGPIO(4) 💖

ok so bestie, we're reading the chvgpio page from the Kernel Interfaces Manual — yes it's a section 4 situation, we're deep in driver territory and honestly? it's giving hardware, it's giving silicon, it's giving slay 💅

✨ NAME ✨

chvgpio — the Intel Cherry View SoC GPIO controller, aka the little guy that handles all the pins 🎀

🌸 SYNOPSIS 🌸

device gpio
device chvgpio

that's it. that's the whole vibe. two lines. iconic. 🦋

💜 DESCRIPTION 💜

ok so chvgpio supports the GPIO controller that lives inside Intel's Cherry View SoC family. periodt. 🍓

The Cherry View SoC has 5 banks of GPIO pins, and their names are: NORTH, EAST, SOUTHEAST, SOUTHWEST and VIRTUAL. like a whole friend group fr fr.

All of them except VIRTUAL are exposed to userland as /dev/gpiocN, where N is 0-3. so four of the five get to go outside, and VIRTUAL is the homebody 🫶 no shade.

Pins in each bank are pre-named to match the names in the Intel® Atom™ Z8000 Processor Series Vol 2. so if u were wondering "why is this pin called that", bestie it's because the manual said so 😭✨
