From eb1e4f43e0f47f2655372c7d32c43db9711c278e Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Fri, 12 Apr 2013 14:08:47 +0000 Subject: kvm/ppc/mpic: add KVM_CAP_IRQ_MPIC Enabling this capability connects the vcpu to the designated in-kernel MPIC. Using explicit connections between vcpus and irqchips allows for flexibility, but the main benefit at the moment is that it simplifies the code -- KVM doesn't need vm-global state to remember which MPIC object is associated with this vm, and it doesn't need to care about ordering between irqchip creation and vcpu creation.
