Hi, Philipp,
I can answer sensor related questions.
Intel sensor hub exposed sensors can be divided into two types:
1. Physical sensors, they have physical sensor devices, such as accelerometer sensor, gyroscope sensor, light sensor, temperature sensor.....
2. Virtual sensors, they are usually fusion sensors which uses algorithm to integrate multi physical sensors, such as orientation sensor, hinge sensor, gesture detection sensor...... they are usually exposed as customer sensors.
For physical sensors, there is no algorithm processing, so get_input_report (read one sample from sysfs node) is very simple to implementation, just read the data out from physical devices.
But for virtual sensor, it involved algorithm processing in FW side, it's more complex and more delay introduced, some of processing may causes timeout in host middleware.
In order to have best compatibility, Intel Sensor Hub decides:
1. For Physical sensor, read out real sensor data to support get_intput_report command
2. For Virtual sensor, use 0 to support get_input_report command
3. No impact to streaming mode (IIO buffer mode), both physical sensors and virtual sensors should report real data in streaming mode.
This is FW behavior, and it has worked for several years.
Anyway, there is another case which also can cause 0 value:
OEM exposed a sensor whose depended physical sensor is missing or not working, this causes a sensor exposed to OS but not work.
If read out all 0 value from both IIO sysfs node and IIO buffer mode, this is the case.
If read out all 0 value from IIO sysfs node, but can get real value from IIO buffer mode, then this sensor should be a virtual sensor.
Hope above information can help answer your questions.
Thanks!
Best Regards,
Even Xu

Try this:
