class RootDevice

Defined at line 30 of file ../../src/ui/input/drivers/goldfish_sensor/root_device.h

A goldfish multisensor device manages multiple sensor InputDevices.

It reads all raw goldfish pipe input on "goldfish:qemud:sensor" pipe,

converts them into sensor report formats, and dispatch to corresponding

sensor devices.

zx_status_t Setup (const std::map<uint64_t, InputDeviceInfo> & input_devices)

Initialize goldfish pipe reader, get a binary mask of all available

sensors, and create an input device for each sensor available.

Returns:

- |ZX_OK| if both sensor query and creation succeed.

- |ZX_ERR_INTERNAL| if cannot read from goldfish pipe.

- |ZX_ERR_INVALID_ARGS| if available sensor mask is invalid.
