gpio-pinctrl extension
This extension provides Intel GPIO/Pinctrl drivers for Apollo Lake platforms.
Installation
Included Modules
pinctrl-intel- Intel pinctrl core driverpinctrl-broxton- Intel Apollo Lake (Broxton) pinctrl driver
Usage
Enable the modules in your machine configuration:
machine:
kernel:
modules:
- name: pinctrl-intel
- name: pinctrl-broxton
Verification
Check that modules are loaded:
talosctl -n <node-ip> read /proc/modules | grep pinctrl
Expected output:
pinctrl_broxton 24576 0 - Live 0x...
pinctrl_intel 40960 1 pinctrl_broxton, Live 0x...
Verify GPIO devices are available:
talosctl -n <node-ip> ls -la /dev/gpiochip*
Check dmesg for driver initialization:
talosctl -n <node-ip> dmesg | grep -i 'pinctrl.*INT3452'
Testing with libgpiod
From a privileged pod with /dev mounted:
gpiodetect
gpioinfo
Troubleshooting
Module not loading
Ensure the extension is properly installed and the modules are listed in your machine config.
No /dev/gpiochip* devices
Verify Talos is running a kernel built with CONFIG_GPIO_CDEV=y. Check dmesg for pinctrl driver initialization messages.
ABI/signature errors
Ensure the extension was built against the same kernel version as your Talos installation.
