Hello I'm having some weird problems with perfmon2 on a 2.6.27.2 kernel patched with the newest perfmon patch.
This is on an Intel Core machine. For some reason, any counter I read seems to have at least 2^32 added to it, sometimes multiple times that. For example: chocovic:~% pfmon /bin/true 4295152148 UNHALTED_CORE_CYCLES chocovic:~% pfmon /bin/true 4295148838 UNHALTED_CORE_CYCLES chocovic:~% pfmon /bin/true 4295151887 UNHALTED_CORE_CYCLES chocovic:~% pfmon -e instructions_retired /bin/true 4295090034 INSTRUCTIONS_RETIRED chocovic:~% pfmon --version pfmon version 3.6 Date: Oct 21 2008 Copyright (C) 2001-2007 Hewlett-Packard Company Possibly relevant boot messages: perfmon: version 2.82 perfmon: CPU hotplug support enabled perfmon: Intel Core PMU detection failed perfmon: detected architecural perfmon v1 perfmon: num_gen=2 width=40 num_fixed=0 width=0 perfmon: Intel architectural PMU installed perfmon: processor does not have PEBS support perfmon: added sampling format default CPU info: cpu family : 6 model : 14 model name : Genuine Intel(R) CPU T2300 @ 1.66GHz stepping : 8 Thanks for any help on this issue...
