Hey, I'm trying to integrate the accelerometer of the Lenovo Yoga into GNOME and a modern desktop. The accelerometer is exported through an IIO device as per: https://github.com/pfps/yoga-laptop/blob/master/sensors/orientation.c We already have some integration for accelerometers in udev/systemd and GNOME, and they rely on the accelerometer being an input device, being tagged with the ID_INPUT_ACCELEROMETER and sending out a kevent/uevent when a major orientation change took place. This is handled by: http://cgit.freedesktop.org/systemd/systemd/tree/src/udev/accelerometer/accelerometer.c for the WeTab/Pegatron devices for example. So, my question regarding the IIO user-space API is: is it possible to make the IIO accelerometer send out a kevent when the orientation changes in a major way (using triggers?) or does user-space need to poll the device instead? If the former, I intend on writing a small helper to set up the accelerometer, and a helper similar to the one already in the udev tree. If the latter, I'll probably write a long-running helper, which would offer the same interface as the one used by the Pegatron accelerometer driver, so that we don't need to make any more changes to user-space.
