Hi All, This patch series support enabling HV and PR KVM together in the same kernel. We extend machine property with new property "kvm_type". A value of "HV" will force HV KVM and "PR" PR KVM. If we don't specify kvm_type we will select the fastest KVM mode. ie, HV if that is supported otherwise PR. With Qemu command line having -machine pseries,accel=kvm,kvm_type=HV [root@llmp24l02 qemu]# bash ../qemu failed to initialize KVM: Invalid argument [root@llmp24l02 qemu]# modprobe kvm-pr [root@llmp24l02 qemu]# bash ../qemu failed to initialize KVM: Invalid argument [root@llmp24l02 qemu]# modprobe kvm-hv [root@llmp24l02 qemu]# bash ../qemu now with -machine pseries,accel=kvm,kvm_type=PR [root@llmp24l02 qemu]# rmmod kvm-pr [root@llmp24l02 qemu]# bash ../qemu failed to initialize KVM: Invalid argument [root@llmp24l02 qemu]# [root@llmp24l02 qemu]# modprobe kvm-pr [root@llmp24l02 qemu]# bash ../qemu Changes from V1: * Build fixes for BOOKE (only compile tested) * Address review feedback -aneesh -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
