Abstract: A computer includes a processor and multiple components directly or indirectly connected to the processor. Each component is coupled to a control device, and is configured to provide resources for one or more application programs running in the computer. The processor, when executing an application program, attaches a tag to an application request, and sends the tag-attached application request to a control device coupled with a component to which the tag-attached application request is directed. The control device receives the tag-attached application request, determines, based on the tag and a resource allocation policy, an amount of resources in the component and instructs the component to allocate the amount of resources and process the application request in accordance with the amount of resources allocated for the application request.

Abstract: A global memory sharing method includes counting, by the sub-operating system, a page replacement rate in a task scheduling period of a predetermined quantity of times, and a memory residence time ratio in a page replacement period; calculating, by the sub-operating system, a memory pressure index according to the page replacement rate and the memory residence time ratio; and if the memory pressure index is greater than a memory pressure threshold, sending, by the sub-operating system, an application to a global memory management service module. According to the forgoing method, in an architecture of multiple operating systems, each sub-operating system can complete much adaptive work, which reduces complexity of the global memory management service module and improves system performance. Meanwhile, a utilization rate of global memory may be improved, and the architecture of the multiple operating systems may have better extensibility.

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.
