Regarding perf top utility in linux

[ankur dwivedi]

Hi,

The perf top utility on linux displays the samples and the pcnt values for
each function. I looked into the code of perf top in builtin-top.c in the
linux kernel. What i have understood is perf top does not display the actual
hardware performance counters value in the samples. It just maintains a
software counter for each event for each function entry in the symbol table
and increments the counter when that function causes a particular event. Is
my understanding correct?
