Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] In the embodiment of the present invention, based on the Bare-metal virtualization (Bare-metal virtualization) method, a CPU virtualization method based on processor partition technology is proposed. According to the expected task classification, it is divided into H-Core partitions and the corresponding number of G-Core partitions; the privileged domain and management tasks running in the virtualization system are deployed to the H-Core, and independent CPU cores and computing resources are assigned to them ;Divide the general client Domain running in the virtualization system into multiple virtualization task subsets according to time constraints, IO access requirements, security and reliability requirements, and deploy them to the corresponding G-Core partitions; and At the same time, on different G-Core partitions, according to the characteristics ...

Abstract

The invention provides a CPU virtualization method based on processor partitioning technology, which comprises the following steps: aiming at a multi-core or many-core platform, firstly, dividing a CPU core into a management core (H-Core) partition and a plurality of general core (G-Core) partitions; then, allocating management tasks and privileged domains in a VMM into the H-Core partition for operating; dividing general client domains operating on the VMM into different virtualization task subsets according to individual characteristics; and allocating the virtualization task subsets into the corresponding G-Core partitions for operating. Different scheduling policies and resource allocation policies can be realized aiming at different types of virtualization tasks in different CPU partitions. The CPU virtualization method of the invention improves the safety and the reliability of the virtualization system on the multi-core or many-core platform, reduces the complexity of CPU virtualization, simultaneously simplifies the complexity of overall resource allocation and scheduling, improves the capacity of the VMM for allocating and scheduling computing resources, and has the advantages of safety, reliability, high efficiency and high performance.

Description

technical field [0001] The invention proposes a CPU virtualization method, in particular relates to a multi-core or many-core platform-oriented CPU virtualization method based on processor partition technology, and belongs to the technical field of computer operating systems and virtualization. Background technique [0002] With the development of the information industry, the requirements for computing power in all walks of life continue to increase. At the same time, limited by the microelectronics production process, traditional methods of increasing circuit integration and CPU main frequency cannot solve problems such as design complexity, chip power consumption, circuit leakage current, and CPU heat dissipation. Therefore, more and more processor manufacturers are turning to single-chip multi-processor (CMP, Chip Multi-processing) technology and simultaneous multi-threading (SMT, Simultaneous Multi-Threading) technology, using the thread-level parallelism of the process...
