Embodiment Construction

[0039] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0040] In the embodiment of the present disclosure, the Hypervisor creates several Guest OSs according to the user configuration, and multiple Guest OSs run on the Hypervisor. Since each CPU may be divided into multiple clusters, and each cluster represents a different core, such as A55 This small core or the A72 large core, and each cluster may run one or more Guest OSs in multiple scenarios.

[0041] In the embodiment of the present disclosure, the operating frequency of the core where the Guest OS is located is determined by the current load of the computing core and the voting mechanism, so as to realize the acquisition and evaluation of the number of tar...

Abstract

The invention relates to a Hypervisor-based dynamic frequency modulation method and electronic equipment, a plurality of guest operating systems (Guest OSs) run on a virtual machine monitor (Hypervisor), and the method comprises the following steps: counting the current load of a core where each Guest OS is located; judging whether the current load is matched with the current operation frequency of the core or not; if not, voting is initiated to each Guest OS, and the current vote number returned by each Guest OS is received; wherein the current number of votes is used for indicating the number of target services on each Guest OS; and performing frequency modulation according to the current number of votes returned by each Guest OS and the current load of the core where each Guest OS is located. According to the scheme, the technical problem that in the prior art, in a Hypervisor-based multi-system environment, corresponding dynamic frequency modulation needs to be carried out on each Guest OS, and implementation is complex is solved, frequency modulation can be reasonably and intelligently carried out, power consumption and performance can be achieved at the same time, and therefore frequency modulation can be carried out on the whole CPU more reasonably.

Description

technical field [0001] The present disclosure relates to the technical field of computers, and in particular, to a Hypervisor-based dynamic frequency modulation method and electronic equipment. Background technique [0002] Hypervisor is called a virtual machine monitor (Virtual Machine Monitor, referred to as VMM), which is an operating system that runs other operating systems. The hypervisor is an intermediate operating system running between the physical hardware and the operating system, which allows multiple operating systems and applications to share a set of basic physical hardware. The operating system running on the hypervisor is called the guest operating system (Guest OS) . [0003] Hypervisor has been used in the server field before, but with the development of embedded systems, it is considered to be the next frontier field of embedded systems to solve the decision-making difficulties of the limited resource utilization of embedded systems in increasingly compl...
