Bartosz Golaszewski ae88d2ff59 gpiod-sysfs-proxy: new recipe ... Many users are reluctant to use libgpiod instead of the deprecated /sys/class/gpio interface. The gpiod-sysfs-proxy project aims at making the transition easier by implementing a compatibility layer in user-space using FUSE and python3-gpiod. This way we can eat the cookie by disabling the sysfs ABI and have the users have it too by sticking to their existing scripts. The project itself is a very simple setuptools-based python package but the recipe is quite complex due to comprehensive distro integration. By default we use /run/gpio as mountpoint. For full backward compatibility with the kernel interface, the user must explicitly add the 'sys-class-mount' switch to PACKAGECONFIG. We do this because, depending on whether CONFIG_GPIO_SYSFS Kconfig option is enabled, /sys/class/gpio will either be non-empty or not exist at all. In the latter case, we need to somehow create the /sys/class/gpio and, since user-space is not allowed to mkdir() inside sysfs, we use overlayfs for that. As this is rather non-standard, we want the user to be aware of this. We support both systemd and sys V init managers. We also provide a ptest package which uses an external gpio-sysfs-compat-tests script.
