Inter-processor interrupts in QEMU

[Arnabjyoti Kalita]

Hello all,

I have a requirement to detect when inter-processor interrupts happen
on running a VM with 2 vcpus (using -smp 2). I realize that sending an
IPI leads to a VMEXIT in the source vcpu. How is this emulated when
QEMU runs in KVM mode (-enable-kvm) ?  Is there a way to detect when
an IPI is raised?

The guest and host architecture is both x86_64. My host runs Linux 5.8.0.

Thank you very much for your reply.

Best Regards,
