Hey, Over the last weeks, there has been some discussion regarding paravirt lpj calculation for kvm. Here's my shot at that. KVM hypervisor already put the right value in our pvclock structures, as part of the xen compatibility efforts. So the first patch moves the respective xen code to pvclock.c (since we'll be doing the same calculation anyway), while the second, implements functions

Respin of the paravirt clock patch series. On the host side the kvm paravirt clock is made compatible with the xen clock. On the guest side some xen code has been factored out into a separate source file shared by both kvm and xen clock implementations. This time it should work ok for kvm smp guests ;) cheers, Gerd

paravirt clock source patches, next round, with a bunch of changes in the host code according to Avi's review comments and some minor code tweaks. cheers, Gerd

paravirt clock source patches, next round. There is now a pvclock-abi.h file with the structs and some longish comments in it and everybody is switched over to use the stuff in there. cheers, Gerd

paravirt clock source patches, next round. There is now a pvclock-abi.h file with the structs and some longish comments in it and everybody is switched over to use the stuff in there. Some minor tweaks after super-fast review by Jeremy. The queue is on top of the kvm git tree. The first two patches should have no kvm dependencies and should apply to linus tree just fine. cheers, Gerd
