Hello,

I am trying to understand the kvm code. I am writing simple code in
which I want to send some message or notification from the guest to
host (qemu-kvm).

I thought of implementing some hypercalls in which, on some condition
this hypercall will get called and it get handled in qemu-kvm. But I
didn't understand how to handle this in qemu-kvm.

Or is there any other better way to do this?

Look at

  cpu_register_io_memory()
  cpu_register_physical_memory()

or

  ioport_register()
