Abstract: A method and an apparatus for implementing device sharing, which are applied to a local system in a heterogeneous system that includes the local system and a peer system, where the peer system have a peripheral device. The method executed by the local system includes: acquiring identifier information of a peripheral device of the peer system; generating according to the acquired identifier information and according to a message format that can be locally identified, an operation request against the peripheral device managed by the peer system; and parsing out from the operation request, a request message including a parameter necessary to generate the operation request, and notifying the peer system of the request message. According to the method, the local system can access a peripheral device of the peer system, thereby implementing peripheral device sharing in the heterogeneous system.

Abstract: A method and an apparatus for accessing physical resources, is used to restrict access to physical resources of other light system kernel Light OSs by a first Light OS in a multi-kernel operating system and ensure security of accessing physical resources among the Light OSs. A method, executed by secure firmware, includes: receiving a physical address corresponding to a physical resource to be accessed by the first Light OS; determining whether the physical address corresponding to the physical resource is out of bounds; and if the physical address corresponding to the physical resource is within bounds, sending an access continuity signal to the first Light OS; or if the physical address corresponding to the physical resource is out of bounds, sending an access error signal to the first Light OS.
