[Xen-devel] ipi(inter-processor interrupt) about xen hypervisor

[zhang zhi <zhangzhi2022@xxxxxxxxxxx>]

Dear Mr. Tim,

          I wanna ask you a question, hope you won’t mind the inconvenience that I gave to you.

 

         In the context of multi-core mode, core 1 is in root-mode, meaning that it’s running VMM. And core 2 is in non-root mode, meaning that it’s running guest OS in kernel level. If core 1 wants core2 to execute a pre-defined program located in kernel-mode, say a syscall or a virtual external interrupt handler(the program is completed via syscall or another kernel module). Considering that core1 is in vmm mode, and core2 is not supposed to vm-exit, so I can’t use the method of event-delivery. What kind of thing should core 1 do ?

         Can you give me some advice ?

Thanks a lot !

 

Best Regards,

Zhang.
