Resource management method, host, and endpoint

摘要

The present invention provides a resource management technology, which can be applied to a host. The host comprises a CPU, an endpoint connected to the CPU, and an I/O device connected to the endpoint. The method comprises: the CPU allocates a target endpoint to a target process, the target endpoint being provided with a virtual device; the target endpoint obtains a performance specification of the target process, and adjusts a performance parameter of the virtual device according to the performance specification, the adjusted virtual device meeting a total requirement of performance specifications of all processes allocated to the target endpoint; and when needing to access a resource in a running process, the target process obtains, from the I/O device, a resource meeting the performance specification of the target process, and provides the obtained resource to the target process for use.
