The ti-sgx-ddk driver requires an additional userspace initialization step after the kernel module has probed the device. Without this initialization, no EGL context can be created and Weston etc. will fail to start. The driver package contains an init script, but this does not work on pure systemd-based systems without sysvinit compat support (as provided by the systemd-compat-units package). Introduce an enabled-by-default PACKAGECONFIG that installs a udev rule instead to run the init command automatically when the driver is loaded, solving the issue without depending on a specific init system. On builds without udev, this PACKAGECONFIG can be disabled, reverting to the old init script-based solution. udev reports several events when the pvrsrvkm module is loaded: - add event for the kernel module - add events for two DRM devices - bind event for the GPU platform device The DRM devices aren't nice to match on, and the kernel module add is too early to run `pvrsrvctl --start`, so we trigger on the platform device bind. Tested with Weston 9.0.0 on the AM65x-based TQ-Systems MBa65xx. Signed-off-by: Matthias Schiffer <matthias.schiffer@ew.tq-group.com> Signed-off-by: Ryan Eatmon <reatmon@ti.com>
