hi, adding support to display diff for more than 2 perf.data files. The basic idea is describe in the initial RFC in here: https://lkml.org/lkml/2012/11/28/200
It's rebased on current Arnaldo's perf core with Namhyung's changes. Attached patches: 01/14 perf diff: Use internal rb tree for hists__precompute 02/14 perf hists: Rename hist_entry__add_pair arguments 03/14 perf tools: Add struct perf_hpp_fmt into hpp callbacks 04/14 perf tools: Centralize default columns init in perf_hpp__init 05/14 perf diff: Introducing diff_data object to hold files 06/14 perf diff: Switching the base hists to be pairs head 07/14 perf hists: Marking dummy hists entries 08/14 perf diff: Display data file info ahead of the diff output 09/14 perf diff: Move diff related columns into diff command 10/14 perf diff: Move columns into struct data__file 11/14 perf diff: Change diff command to work over multiple data files 12/14 perf diff: Update perf diff documentation for multiple data comparison 13/14 perf diff: Making compute functions static 14/14 perf diff: Add generic order option for compute sorting thanks, jirka Cc: Arnaldo Carvalho de Melo <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Ingo Molnar <[email protected]> Cc: Paul Mackerras <[email protected]> Cc: Corey Ashford <[email protected]> Cc: Frederic Weisbecker <[email protected]> Cc: Namhyung Kim <[email protected]> --- tools/perf/Documentation/perf-diff.txt | 79 +++++++++-- tools/perf/builtin-diff.c | 673 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++----------------- tools/perf/builtin-report.c | 1 - tools/perf/ui/browsers/hists.c | 12 +- tools/perf/ui/gtk/browser.c | 12 +- tools/perf/ui/hist.c | 298 ++++++++++------------------------------- tools/perf/ui/setup.c | 1 - tools/perf/ui/stdio/hist.c | 4 +- tools/perf/util/hist.c | 1 + tools/perf/util/hist.h | 24 +--- tools/perf/util/sort.h | 9 +- 11 files changed, 717 insertions(+), 397 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
