Information regarding the perf tool

[Harald Servat <harald.servat@bsc.es>]

Dear list,

    I'm wondering whether it be possible to extend the "perf mem" (tool) 
to emit the TSC of the sampling event?

    I started looking at the code, and I'd like to understand how does 
the perf tool work to extend that tool providing such functionality. 
However, I'm clueless on how the perf tool works. I have a machine with 
kernel 3.11.0 and its source code and within the source code in 
tools/perf/builtin-mem.c I observe that the application is somehow 
executed through "cmd_record ()" but I don't see the implementation of 
cmd_record() around. Would anyone on the list giving me some hints on 
how this is done?

   Additionally, it seems that perf.data is a file that mostly contains 
perf_event that represent the data gathered. It seems to be defined in 
include/linux/perf_event.h, but it doesn't seem to me a simple container 
for performance data. Is that the struct I'm looking for?

Thank you very much.
