Here is a new version of this series. I am definitely leaving any warp calculations out, as Jeremy wisely points out that Chuck Norris should perish before we warp. Also, in this series, I am using KVM_GET_SUPPORTED_CPUID to export our features to userspace, as avi suggets. (patch 4/7), and starting to use the flag that indicates possible tsc stability (patch 7/7), although it is still off by default. Glauber Costa (7): Enable pvclock flags in vcpu_time_info structure Add a global synchronization point for pvclock change msr numbers for kvmclock export paravirtual cpuid flags in KVM_GET_SUPPORTED_CPUID Try using new kvm clock msrs don't compute pvclock adjustments if we trust the tsc Tell the guest we'll warn it about tsc stability arch/x86/include/asm/kvm_para.h | 13 ++++++++ arch/x86/include/asm/pvclock-abi.h | 4 ++- arch/x86/include/asm/pvclock.h | 1 + arch/x86/kernel/kvmclock.c | 56 ++++++++++++++++++++++------------- arch/x86/kernel/pvclock.c | 37 +++++++++++++++++++++++ arch/x86/kvm/x86.c | 37 +++++++++++++++++++++++- 6 files changed, 125 insertions(+), 23 deletions(-) -- 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
