IGPIO(4)

🌸 NAME 🌸

okay so igpio(4) — Intel GPIO Controller — is the page you're looking for, bestie. It's from the Kernel Interfaces Manual, and it's all about the igpio driver handing you a gpio(4) interface. 💖

✨ SYNOPSIS ✨

igpio* at acpi?
gpio* at gpiobus?

💅 DESCRIPTION 💅

igpio is literally giving gpio(4) interface energy for this whole Intel chipset squad:

• Alder Lake-N
• Alder Lake-P
• Alder Lake-S
• Cannon Lake-H
• Cannon Lake-LP
• Cedarfork
• Coffee Lake-S
• Denverton
• Emmitsburg
• Gemini Lake
• Ice Lake-LP
• Ice Lake-N
• Jasper Lake
• Lakefield
• Lewisburg
• Raptor Lake-S
• Sunrisepoint-H
• Sunrisepoint-LP
• Tiger Lake-H
• Tiger Lake-LP

🚨 Important vibe check: support for Baytrail, Broxton, Cherryview and Lynxpoint are not enabled yet. Like, not yet, bestie. Don't come for me. 💀

This driver is down with these pin flags:

• GPIO_PIN_INPUT — input capability, slay
• GPIO_PIN_OUTPUT — output capability, slay
• GPIO_PIN_INOUT — inout capability, slay
• GPIO_PIN_ININ — inin capability, keep it exactly like that
• GPIO_PIN_PULLUP — pullup capability
• GPIO_PIN_PULLDOWN — pulldown capability

and the interrupt capabilies are:

• GPIO_INTR_POS_EDGE — positive-edge interrupt capability
• GPIO_INTR_NEG_EDGE — negative-edge interrupt capability
• GPIO_INTR_DOUBLE_EDGE — double-edge interrupt capability
• GPIO_INTR_HIGH_LEVEL — high-level interrupt capability
• GPIO_INTR_LOW_LEVEL — low-level interrupt capability

🌈 SEE ALSO 🌈

• gpio(4) — the other manual page you should go read, bestie 🫶

⭐ HISTORY ⭐

The igpio driver first appeared in NetBSD 10.0. Periodt. ✨

— okay that's the whole vibe! This page is from Debian, dated February 27, 2023, and it's the IGPIO(4) manual page. Byeee bestie, go have a slay day 💖✨
