-- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1953613 Title: GPIO character device API not enabled in kernel Status in linux package in Ubuntu: Confirmed Bug description: The current versions of gpiod, libgpiod-dev and libgpiod2 (1.6.2-1) use version 1 of the GPIO character device API. However, they cannot work because the interface is disabled in the default kernel (tested with 5.13.19). After rebuilding the kernel with the option CONFIG_GPIO_CDEV_V1=y, the gpiod tools work as expected. Thanks to Marek Szuba, who reported the same bug for Gentoo (https://bugs.gentoo.org/807334), pointing me in the right direction.
