Hypervisor Inter-Core Communication Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inter-core communication methods in computer systems expose hardware resources, leading to security risks and inability to support multi-operating system scenarios, as they lack effective isolation between software and hardware.
Innovation Solution
Implementing a virtual machine monitor (Hypervisor) that runs between the operating system and the physical server, managing inter-core communication by writing data into a preset memory, triggering CPU cores, and feeding back feedback data, thereby isolating the operating system from hardware resources and enabling communication between multiple operating systems and CPU cores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an operating system runs directly on hardware resources of a server, then data communication between software and hardware is simplified, but hardware resources are completely exposed leading to security risks
Solution Approach 1:
A virtual machine monitor is introduced as an intermediary layer between the operating system and hardware resources. The virtual machine monitor intercepts and manages inter-core communication data, preventing direct OS access to hardware while maintaining communication functionality. This mediator approach resolves the contradiction by enabling data communication through controlled interfaces while securing hardware resources behind the virtualization layer.
2Productivity
If an operating system runs directly on hardware resources, then inter-core communication is direct and efficient, but multiple operating systems cannot share the same physical server resources
Solution Approach 1:
The virtual machine monitor provides universal access control for multiple operating systems to share physical server resources. It manages inter-core communication data from different OS instances, routing and securing communications while enabling multiple OS environments to coexist on the same hardware platform. This multi-functional approach allows both communication efficiency and multi-OS support.
Solution Approach 2:
The system segments inter-core communication data into virtualized communication channels managed by the virtual machine monitor. Each operating system operates in its own virtualized context, with communication data segmented and routed appropriately. This segmentation enables multiple OS instances to share hardware resources while maintaining isolated, efficient communication paths for each.
3Ease of operation
If hardware resources are completely exposed to the operating system, then direct access and control are achieved, but information security is compromised
Solution Approach 1:
The virtual machine monitor serves as a security intermediary that filters and controls all inter-core communication data between the operating system and hardware resources. It maintains direct access control capabilities while blocking unauthorized information exposure, thus resolving the contradiction between ease of hardware control and information security protection.

AI summary
The present application proposes a method and an apparatus for processing inter-core communication, and a computer system, and the method includes: acquiring inter-core communication data sent by a target operating system; writing a communication data content in the inter-core communication data into a preset memory, and triggering a target CPU core to read the communication data content from the preset memory; acquiring communication feedback data, where the communication feedback data is feedback data corresponding to the communication data content and sent by the target CPU core; and feeding back the communication feedback data to the target operating system. By adopting the above method for processing inter-core communication, security of a hardware resource in a process of the inter-core communication may be ensured.
