Hello,everyone!
      I installed the libpfm4 on the Intel core i3-550. The OS is FC12. And the 
kernel is 2.6.31. However,  my platform can not be detected by the example 
program which located in the example directory. The example is checkinfo.  I 
mean that the PMU model can not be detected.  I think core i3 should be 
core-nehelem architecture, but the detected  pmu model  is general x86 
architecture and core architecture. I want to know if there are any matters 
when I using the libpfm4 to sample the nehelam performance events. I mean that 
I contiune use the libpfm4 interface to sample the nehalem specified permance 
events even if it  can not  detect the PMU model correctly.  Any suggestions? 
or I should update the libpfm4.
Best regards!
Jason
