Hi list, i played around with the full virtualized performance counters (vpmu stuff) on intel core2 processors in a HVM guest. I got something to work on the processor family=6 and model=15. But with newer processors (model=26 -> E5520 and model=29 -> X7460) nothing happens. I searched a little bit in the sources and found in vpmu_initialise() that only for model 15 and 23 the vpmu->arch_vpmu_ops gets initialized. Is this missing or do I something wrong? Maybe anybody is working on this? Thanks in advance for all hints! Dietmar. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
