Embodiment
[0021] A method for realizing the response of an embedded virtual machine's hard real-time virtual timer, the steps are as follows: by constructing a timer interrupt dispatch table in the Hypervisor, the limited hardware timer interrupts are directly distributed through the interrupt dispatch table of the Hypervisor, thereby reducing The delay brought by the original virtual machine event channel, virtual clock and other methods can realize the sharing of limited hardware timer interrupts in the embedded processor platform among multiple partitions.
[0022] Such as figure 1 As shown, the steps of the response method are as follows:
[0023] 1) Set a 32-bit timer in the embedded processor platform, including timer 1 and timer 2, and set the virtual machine with virtual machine partition 1 (VM1) and virtual machine partition 2 (VM2).
[0024] 2) Timer 1 is used for the system clock of the Hypervisor to provide a virtual clock interrupt for the partition operating system and ma...
