Unlike other platforms, PPC64 supports 2 types of KVM: 1. PR KVM emulated in user space - works on every PPC64 platform, even on old POWERMAC; does not require hypervisor-enabled host CPU (POWER5+ and newer); does not require OPAL; 2. HV KVM - this requires hypervisor-enabled CPU and OPAL - i.e. recent POWER7/8 CPUs running as a "powernv" platform only. So PPC64 KVM is split into 3 kernel modules - kvm_pr, kvm_hv and kvm, the latter contains bits of code common for both types of KVM. Recent QEMU supports a "kvm-type" machine option and can instantiate the requested type of KVM. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru>
