I am new to oprofile. I am trying to count the number FP_TRUE_SIRSTALL events which correspond to Floating point software assist faults if I am not wrong. When I execute a code, I get a lot of FPSAW messages on the console. However, when I try with opfrofile and event FP_TRUE_SIRSTALL, it says “cannot locate any sample file”. When I use one more event with this event, it shows the collected data for thet other event and for this event it says “cannot locate any sample file”. Am I missing something? I tried with count as high as 400000 and as low as 5000.
Any help is appreciated.
I am suing RHEL 3.0 and oprofile that came along with it. Itanium2 McKinley.
