simple question about xenoprof

simple question about xenoprof

I'm trying to use xenoprof in my machine (xeon x5650, westmere).

 

While oprof works for this machine correctly, xenoprof doesn't work
properly. 

 

I want to use xenoprof in NMI mode (which is the opposite side of timer
mode, right?)

 

However, kernel message always shows that xenoprof works in the timer mode
only. 

 

Is there any restriction or specs which is not affordable to run xenoprof? 

 

As I said, my machine has xeon x5650, westmere. 

+

Dom0 with kernel 2.6.32

Xen 4.0.1 version

 

 

 

 

Thanks.

Right. It needs to be fixed. Patches are most appreciated :-)
