Thanks, applied all but: [PATCH 17/25] perf callchain: Allow for max_stack greater than PERF_MAX_STACK_DEPTH Please take a look at the comments I made on this and a few others that I applied, - Arnaldo > First 3 patches are minor fixes: > > perf auxtrace: Fix 'instructions' period of zero > perf report: Fix sample type validation for synthesized callchains > perf intel-pt: Fix potential loop forever > > Next 4 are minor improvements: > > perf intel-pt: Make logging slightly more efficient > perf script: Allow time to be displayed in nanoseconds > perf tools: Warn when AUX data has been lost > perf tools: Add more documentation to export-to-postgresql.py script > > Next 7 add support for branch stacks: > > perf auxtrace: Add option to synthesize branch stacks on samples > perf report: Adjust sample type validation for synthesized branch stacks > perf report: Also do default setup for synthesized branch stacks > perf report: Skip events with null branch stacks > perf inject: Set branch stack feature flag when synthesizing branch stacks > perf intel-pt: Move branch filter logic > perf intel-pt: Support generating branch stack > > Next 6 allow for arbitrary-sized call stacks: > > perf report: Make max_stack value allow for synthesized callchains > perf hists: Allow for max_stack greater than PERF_MAX_STACK_DEPTH > perf callchain: Allow for max_stack greater than PERF_MAX_STACK_DEPTH > perf script: Add a setting for maximum stack depth > perf scripting python: Allow for max_stack greater than PERF_MAX_STACK_DEPTH > perf script: Make scripting_max_stack value allow for synthesized callchains > > Final 5 let Intel PT be used with autofdo: > > perf tools: Add perf_evlist__id2evsel_strict() > perf tools: Add perf_evlist__del() > perf inject: Remove more aux-related stuff when processing instruction traces > perf inject: Add --strip option to strip out non-synthesized events > perf intel-pt: Add mispred-all config option to aid use with autofdo > > > Adrian Hunter (25): > perf auxtrace: Fix 'instructions' period of zero > perf report: Fix sample type validation for synthesized callchains > perf intel-pt: Fix potential loop forever > perf intel-pt: Make logging slightly more efficient > perf script: Allow time to be displayed in nanoseconds > perf tools: Warn when AUX data has been lost > perf tools: Add more documentation to export-to-postgresql.py script > perf auxtrace: Add option to synthesize branch stacks on samples > perf report: Adjust sample type validation for synthesized branch stacks > perf report: Also do default setup for synthesized branch stacks > perf report: Skip events with null branch stacks > perf inject: Set branch stack feature flag when synthesizing branch stacks > perf intel-pt: Move branch filter logic > perf intel-pt: Support generating branch stack > perf report: Make max_stack value allow for synthesized callchains > perf hists: Allow for max_stack greater than PERF_MAX_STACK_DEPTH > perf callchain: Allow for max_stack greater than PERF_MAX_STACK_DEPTH > perf script: Add a setting for maximum stack depth > perf scripting python: Allow for max_stack greater than PERF_MAX_STACK_DEPTH > perf script: Make scripting_max_stack value allow for synthesized callchains > perf tools: Add perf_evlist__id2evsel_strict() > perf tools: Add perf_evlist__del() > perf inject: Remove more aux-related stuff when processing instruction traces > perf inject: Add --strip option to strip out non-synthesized events > perf intel-pt: Add mispred-all config option to aid use with autofdo > > tools/perf/Documentation/intel-pt.txt | 39 ++++ > tools/perf/Documentation/itrace.txt | 4 + > tools/perf/Documentation/perf-inject.txt | 3 + > tools/perf/Documentation/perf-script.txt | 3 + > tools/perf/builtin-inject.c | 125 +++++++++++- > tools/perf/builtin-report.c | 31 ++- > tools/perf/builtin-script.c | 18 +- > tools/perf/scripts/python/export-to-postgresql.py | 221 +++++++++++++++++++++ > tools/perf/util/auxtrace.c | 24 ++- > tools/perf/util/auxtrace.h | 4 + > tools/perf/util/event.h | 1 + > tools/perf/util/evlist.c | 23 +++ > tools/perf/util/evlist.h | 3 + > tools/perf/util/hist.c | 6 +- > tools/perf/util/hist.h | 1 + > .../perf/util/intel-pt-decoder/intel-pt-decoder.c | 4 +- > tools/perf/util/intel-pt-decoder/intel-pt-log.c | 21 +- > tools/perf/util/intel-pt-decoder/intel-pt-log.h | 38 +++- > tools/perf/util/intel-pt.c | 135 ++++++++++++- > tools/perf/util/machine.c | 2 +- > .../util/scripting-engines/trace-event-python.c | 2 +- > tools/perf/util/session.c | 12 +- > tools/perf/util/trace-event.h | 2 + > 23 files changed, 686 insertions(+), 36 deletions(-) > > > Regards > Adrian -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
