Virtualized Device Event Proxy for Stable Host–Compute Card Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtualization technologies face issues of poor stability and high maintenance costs due to the need for adapting compute cards and virtualized devices, leading to instability and increased development efforts.
Innovation Solution
An inter-application communication method using an event proxy to implement bidirectional mapping between an event file descriptor and a driver, allowing communication between applications on a host and compute card without modifying the virtualized device's code, thereby maintaining system stability and reducing maintenance costs.

Engineering Contradiction Analysis
1Productivity
If the compute card and virtualized device are adapted in advance, then the inter-application communication efficiency is improved, but the system stability deteriorates and maintenance costs increase
Solution Approach 1:
The patent introduces an event proxy as an intermediary component that mediates between the virtualized device and the compute card driver. The event proxy translates events from the virtualized device into driver-compatible formats and vice versa, eliminating the need for direct adaptation between the compute card and virtualized device. This mediator approach maintains communication efficiency while preserving system stability by avoiding tight coupling and pre-adaptation requirements.
2Adaptability or versatility
If the compute card and virtualized device are adapted in advance, then the communication functionality is achieved, but the maintenance costs increase
Solution Approach 1:
The event proxy serves as a maintenance-friendly intermediary that encapsulates the translation logic between virtualized device events and driver interfaces. This centralizes the adaptation logic in a single maintainable component rather than requiring distributed adaptations across multiple systems. The proxy can be updated independently to accommodate changes in either the virtualized device or driver interface, reducing overall maintenance complexity and costs.
Solution Approach 2:
The patent segments the communication system into distinct functional components: the virtualized device, the event proxy, and the driver. This segmentation allows each component to be developed, tested, and maintained independently. The event proxy acts as a boundary layer that isolates changes in one component from affecting others, thereby reducing maintenance costs and improving ease of manufacture.

AI summary
Embodiments of the present disclosure provide an inter-application communication method and apparatus based on a virtualized device, and an electronic device. The method includes: receiving a first event message sent by a first application running in an operating system of a host, where the first event message is used to request a second application running in an operating system of a compute card to perform a target function, and the operating system of the host communicates with the operating system of the compute card through a driver; processing the first event message through an event proxy to generate a second event message including an event file descriptor, where the event proxy is configured to implement bidirectional mapping between the event file descriptor and the driver; and sending the second event message to a virtualized device, to establish a communication channel between the first application and the second application.
