Abstract

Disclosed is a method and device for kernel running in a heterogeneous operating system, applied to a many-core platform. The method comprises: setting cores in a core resource pool of a CPU to be in an idle state; and running at least two cores in the idle state in the core resource pool of the CPU respectively in two designated kernel types in accordance with a running demand, wherein the kernel types comprise: a single kernel and a micro kernel. Also disclosed is a corresponding device for kernel running in a heterogeneous operating system. Cores can run with dynamic transformation between a micro kernel and a single kernel by setting an idle state between two kernel types of single kernel and micro kernel, thereby simultaneously running the single kernel and the micro kernel in the operating system in accordance with the running demand. The device has the advantages of two kernel types.

Description

technical field [0001] The invention relates to the technical field of many-core operating systems, in particular to a method and device for operating kernels in heterogeneous operating systems. Background technique [0002] At present, the processor has entered the multi-core / many-core era, however, the current operating system (Operating System, OS) only uses multi-core / many-core processors in the form of Symmetric Multi-Processing (SMP), which cannot fully Take advantage of the parallel processing capabilities of multi-core / many-core processors. Experiments have proved that when the processor exceeds 16 cores, the performance of the existing Linux operating system does not increase linearly but decreases. Therefore, there are currently many research-based operating systems for many-core platforms. The characteristics of these many-core OSs are: micro-kernel architecture, which is adopted by existing many-core OSes; multi-core design can avoid the performance of a single ...
