2008-06-06KVM: ppc: Remove duplicate functionHollis Blanchard
This was left behind from some code movement. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-05-04KVM: ppc: deliver INTERRUPT_FP_UNAVAIL to the guestChristian Ehrhardt
This patch adds the delivery of INTERRUPT_FP_UNAVAIL exceptions to the guest. It's needed if a guest uses ppc binaries using the Floating point instructions.

2008-05-04KVM: ppc: Handle guest idle by emulating MSR[WE] writesHollis Blanchard
This reduces host CPU usage when the guest is idle. However, the guest must set MSR[WE] in its idle loop, which Linux did not do until 2.6.26. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> Signed-off-by: Jerone Young <jyoung5@us.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-04-27KVM: ppc: PowerPC 440 KVM implementationHollis Blanchard
This functionality is definitely experimental, but is capable of running unmodified PowerPC 440 Linux kernels as guests on a PowerPC 440 host. (Only tested with 440EP "Bamboo" guests so far, but with appropriate userspace support other SoC/board combinations should work.) See Documentation/powerpc/kvm_440.txt for technical details.
