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: The invention provides a hot plug method and device for a byte-addressable persistent memory, which includes hot-add and hot-remove; wherein the hot-add includes physical add and logical add, and the hot-remove includes logical remove and physical remove; the physical add is used for converting the memory from an uncharged raw media into a manageable block of an operating system; the logical add is used for converting the memory from the manageable block of the operating system into a memory device which capable of mapping a virtual address; the logical remove is used for converting the memory device which capable of mapping the virtual address into the manageable block of the operating system; and the physical remove is used for converting the memory from the manageable block of the operating system into the uncharged raw media.

Abstract: A resource processing method, an operating system, and a device are provided. The method is applied to a multi-core operating system, where the multi-core operating system includes a management operating system and multiple load operating systems that run on a host machine and includes a physical resource pool. According to the method, after selecting, in processor cores allocated to a first load operating system, a startup processor core that starts up the first load operating system, the management operating system instructs the startup processor core to read a mapping relationship that is from a virtual memory address to a physical memory address and that is required for executing a startup mirror of the first load operating system. Then, the management operating system instructs the startup processor core to execute the startup mirror pre-constructed for the first load operating system to start up the first load operating system.
