Integrete ISH kernel driver and ISH driver should provoide following interface to user
(1) Batch Mode----Get the hardware batch buffer size/count,Set the batch timeout value
(2) Wakeup/non-wakeup----checking if one sensor is wakeup instance or non-wakeup instance.For wakeup instance, when batch buffer is full or wait timeout, system must be woken up and receive batched sensor events.
(3) Timestamp ---- expose the sensor event timestamp to user space for sync
(4) physical sensors-----support exposing following physical sensors:Accelerometer,Gyroscope,Magnetic,Field,Pressure,Light,Proximity
(5) Advanced sensor----support exposing following advanced sensors:
Gravity,Linear Acceleration,Rotation Vector,Orientation,Game Rotation,Geomagentic Rotation,Step Detector,Step Counter,Terminal,Significant motion,Wakeup Gesture,Glance Gesture,Tilt,PanZoon,Lift and Look
(6)multiple sensor instance support
(7)private command support ---- support set/get path for private command set and response get, because some advanced sensor needs different special command to work properly.
(8)User defined sensor support--- exposing non-pre-defined sensors.
Because customer may add a new sensor in firmware, and hope sensor driver can expose it as a unknown sensor automatically, then application can use it directly without any code change.
HW: Broxton-p
Upstream Schedule:
Basic Sensor Driver: 4.9
Advanced Sensor Driver: TBD |
