+KVM_CLOCK_HOST_TSC. If set, the `host_tsc` field in the kvm_clock_data +structure is populated with the value of the host's timestamp counter (TSC) +at the instant when KVM_GET_CLOCK was called. If clear, the `host_tsc` field +does not contain a value.If the host TSCs are not stable, then KVM_CLOCK_HOST_TSC bit (and host_tsc field) are ambiguous. Shouldnt exposing them be conditional on stable TSC for the host ?
Yes, good point. Paolo _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
