Ok - this series is looking much clearer now. Thanks. Acked-by: Andrew Cooper <[email protected]> (although there is one trivial style issue in patch 1 I can fix on commit). You are still waiting for SVM acks on patches 1 and 3 by the looks of things. One thing I note however is that patch 2 and 3 both turn on intercepts and have no way of turning them back off. This appears to be consistent with the Intel side of things, but it is suboptimal for the guest when an introspection agent detaches. For the CPUID/MSR policy side of things, Jan has talked me in to changing how cpuid_policy_updated() works, and implementing it as a recalculation of the intercepts on the return-to-guest path. It occurs to me that this usefully extends to changes requested by the introspection agent. ~Andrew _______________________________________________ Xen-devel mailing list [email protected] https://lists.xenproject.org/mailman/listinfo/xen-devel
