Is it possible that xenoprof active domain profiling using pvops jeremy''s kernel
....32 with paravirt enabled ), distribution( ubuntu 9.10 )
In passive mode, xenoprof seems to work well, opreport showed good
information.
but, in active mode, it seems not to be done correctly.
my command is strictly followed by xenoprof tutorial doc.

xenoprof bug ?
Hi,
I ran xenoprof with the event mask LLC_MISSES:10000. This should be L2 cache
misses on Core2 arch.
After the run when I run opreport it displays :
Counted *L2_RQSTS* events (number of L2 cache requests) with a unit mask of
0x41 (multiple flags) count 10000
LLC_MISSES:10000 | .....
My questions was whether the message is incorrect or the event mask is not
being set correctly by oprofile.
My guess is that the message is incorrect but I just wanted to confirm....
