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.
