Hi,

the performance registers aren't implemented on QEMU.

Best regards,

Hi,

I'm using qemu at the moment to run a system for debugging purposes.  I
was wondering whether qemu does actually emulate the performance
counters on IA32.  Every time i try to read the value out, it
consistently gives me zero even though i have written to the given model
specific register.

Thanks
