[Xen-users] Don't mount hardware performance counter using xenoprof

[Yuto Nakai <yuto.k2c@xxxxxxxxx>]

Hi,

I want to use xenoprof to profile the overhead of the hypervisor. 
I patched the oprofile-0.9.5 using the patch from xenoprof.sourceforge.net

Debian GNU/Linux 5.0 (lenny)
Xen-4.0.1 + 2.6.32.27 (linux-2.6-pvops.git) Dom0
My platform is Intel(R) Core(TM) i7 CPU           960  @ 3.20GHz

My problems are:
In Dom0,  But hardware performance counters don't be mounted 

after initialization (opcontrol --init)

# ls /dev/oprofile

backtrace_depth    cpu_buffer_size   pointer_size

buffer                    cpu_type            stats 

buffer_size             dump                time_slice 

buffer_watershed    enable

0(and 1,2,3) directories are not exist.

Is there any reason for this ?

Any help is appreciated. Thanks, Yuto Nakai
