hi. does xen provide infrastructure for switching MSR state between different guests? i''m particularly thinking about hardware performance counters, but there may be additional ones, e.g. tsc (questionable, since not guaranteed to be writeable), debug extensions,... are there any opinions or have there be decisions regarding access to performance counters in unprivileged guests at all? i''m aware of DOM0_MSR for privileged ones, but haven''t found much beyond that, yet. regards, daniel -- Daniel Stodden LRR - Lehrstuhl für Rechnertechnik und Rechnerorganisation Institut für Informatik der TU München D-85748 Garching http://www.lrr.in.tum.de/~stodden mailto:stodden@cs.tum.edu PGP Fingerprint: F5A4 1575 4C56 E26A 0B33 3D80 457E 82AE B0D8 735B _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
