虚拟化系统中断处理优化方法、装置、设备及介质
By configuring GIC and VE, MSI interrupts are converted into LPI interrupts, enabling direct data transmission of vehicle processor interrupts. This solves the problem of virtual machines getting trapped in the hypervisor, improves communication efficiency between virtual machines and between virtual machines and the host, and optimizes interrupt handling of the vehicle processor.

AI Technical Summary
Existing virtual machine interrupt handling methods cause virtual machines to get stuck in the hypervisor in automotive processors, consuming a lot of computing power, affecting system performance and real-time response time, and making it impossible to deploy real-time sensitive systems within virtual machines.
By configuring GIC to implement MSI interrupt routing, VE receives requests and initiates MSI interrupt requests. ITS in GIC converts them into LPI interrupts and sends them directly to the VM or Hypervisor, realizing a direct interrupt data transmission mechanism and preventing the virtual machine from getting stuck in the Hypervisor.
Without increasing computing power consumption, efficient communication between virtual machines and between virtual machines and the host was achieved, the interrupt handling of the vehicle processor was optimized, the problem of virtual machines getting stuck in the hypervisor was solved, and the system performance and real-time response capability were improved.
