Problems solved by technology

[0003] However, due to the large differences in the design concept and system architecture between the VxWorks operating system and the Linux operating system, if no corresponding adaptation mechanism is provided, the software originally running on the VxWorks operating system will be transplanted to the Linux operating system. There will be more difficulties, and it is necessary to make major changes to the software originally running on the VxWorks operating system, which will increase the cost of transplanting the software originally running on the VxWorks operating system to the Linux operating system, and reduce the cost of the software. Benefits of Transplantation

Abstract

Embodiments of the invention provide a process scheduling method and device, relate to the technical field of computers, and aim at realizing the preemptive locking function of task scheduling in VxWorks in a Linux user state. The method comprises the following steps: when a CPU core is in a user state, setting a scheduling control identification corresponding to the CPU core; and when the CPU core is in a core state, obtaining the scheduling control identification corresponding to the CPU core, wherein the CPU core is used for process or thread scheduling, and when the scheduling control identification allows scheduling, process or thread scheduling is carried out at the CPU core. The process scheduling method and device provided by the embodiments of the invention are used for process or thread scheduling.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a process scheduling method and device. Background technique [0002] Both VxWorks operating system and Linux operating system are embedded operating systems. With the development of data communication technology, VxWorks operating system has been unable to meet the increasing needs of communication equipment manufacturers in terms of hardware, cost and functions. In this context, communication equipment manufacturers are gradually trying to migrate communication equipment from the VxWorks operating system to the Linux operating system. In this process, due to cost considerations, many software that originally run on the VxWorks operating system need to be transplanted. to the Linux operating system. [0003] However, due to the large differences in the design concept and system architecture between the VxWorks operating system and the Linux operating system, if no correspondi...
