My levelling series actually introduces a dependency tree to properly evaluate the knockon effects of disabling certain features. I am unsure whether it is worth your time to split xsave and avx here, but I certainly wouldn't recommend making it any finer-grained at this stage. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
