perf tools: Add call-graph option support into .perfconfig
Adding call-graph option support into .perfconfig file, so it's now possible use call-graph option like: [top] call-graph = fp [record] call-graph = dwarf,8192 Above options ONLY setup the unwind method. To enable perf record/top to actually use it the command line option -g/-G must be specified. The --call-graph option overloads .perfconfig setup. Assuming above configuration: $ perf record -g ls - enables dwarf unwind with user stack size dump 8192 bytes $ perf top -G - enables frame pointer unwind $ perf record --call-graph=fp ls - enables frame pointer unwind $ perf top --call-graph=dwarf,4096 ls - enables dwarf unwind with user stack size dump 4096 bytes Signed-off-by: Jiri Olsa <jolsa@redhat.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: Corey Ashford <cjashfor@linux.vnet.ibm.com> Cc: David Ahern <dsahern@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1391427883-13443-2-git-send-email-jolsa@redhat.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
