This implements the plan that we discussed at KVM Forum. Patch 3 implements a new function that returns the current value of kvmclock as read by the guest. The function is then used to provide the Hyper-V time reference counter. Now that the reference counter is synchronized with kvmclock, the TSC page can be supported nicely. Paolo v2->v3: use TSC page information to compute time reference counter value fixed case where TSC seq is 0xFFFFFFFE Paolo Bonzini (4): KVM: x86: always fill in vcpu->arch.hv_clock KVM: x86: initialize kvmclock_offset KVM: x86: introduce get_kvmclock_ns KVM: x86: Hyper-V tsc page setup arch/x86/entry/vdso/vclock_gettime.c | 2 +- arch/x86/include/asm/kvm_host.h | 2 + arch/x86/include/asm/pvclock.h | 5 +- arch/x86/kernel/pvclock.c | 2 +- arch/x86/kvm/hyperv.c | 162 +++++++++++++++++++++++++++++++---- arch/x86/kvm/hyperv.h | 3 + arch/x86/kvm/x86.c | 158 ++++++++++++++++++++-------------- arch/x86/kvm/x86.h | 6 +- 8 files changed, 253 insertions(+), 87 deletions(-) -- 1.8.3.1 -- 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
