hi, changing the '-g/-G' options for record/top commands to take NO argument and enable unwind method based on .perfconfig setup (using FP by default).
The current -g option parsing moves into the '--call-graph' option. Examples: $ cat ~/.perfconfig: [top] call-graph = fp [record] call-graph = dwarf,8192 $ 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 thanks, jirka Cc: Corey Ashford <cjash...@linux.vnet.ibm.com> Cc: David Ahern <dsah...@gmail.com> Cc: Ingo Molnar <mi...@elte.hu> Cc: Namhyung Kim <namhy...@kernel.org> Cc: Paul Mackerras <pau...@samba.org> Cc: Peter Zijlstra <a.p.zijls...@chello.nl> Cc: Arnaldo Carvalho de Melo <a...@redhat.com> Cc: Andi Kleen <a...@firstfloor.org> Cc: Adrian Hunter <adrian.hun...@intel.com> --- Jiri Olsa (4): perf tools: Split -g and --call-graph for record command perf tools: Split -G and --call-graph for top command perf tools: Add call-graph option support into .perfconfig perf tools: Add readable output for callchain debug tools/perf/Documentation/perf-record.txt | 6 +++++- tools/perf/Documentation/perf-top.txt | 18 +++++------------- tools/perf/builtin-record.c | 89 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++--------------------- tools/perf/builtin-top.c | 35 +++++++++++++++++++++++++---------- tools/perf/perf.h | 4 +++- tools/perf/util/callchain.h | 3 +++ tools/perf/util/evsel.c | 2 +- 7 files changed, 110 insertions(+), 47 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
