Methods, Devices and Computer Readable Storage Devices for Emulating a Magnetometer in a Guest Operating System from a Host Operating System

摘要

A guest operating system, launched by executing an application associated with a host operating system, is provided with access to a magnetometer associated with a computing device including a processor executing the host operating system. A first application associated with the guest operating system generates a request for magnetometer data. The request is received at a hardware abstraction layer associated with the guest operating system, and the request is sent from the hardware abstraction layer to a second application associated with the host operating system. The request is sent from the second application to a driver executing within a kernel of the host operating system. The driver retrieves the requested magnetometer data from the magnetometer. The retrieved magnetometer data is provided to the first application via the second application and the hardware abstraction layer.
