git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/urgent fixes from Arnaldo Carvalho de Melo: - tracepoint_error() can receive e=NULL, robustify it, fixes a problem noticed with a very specific combination: Machine with Intel PT (e.g. Broadwell), kernel with no perf_event_attr.context_switch feature (e.g. 4.2) and unreadable tracefs (for instance !root users), making the fallback from perf_event_attr.context_switch to the sched:sched_switch tracepoint to fail reading its info from tracefs, fix it. (Adrian Hunter) - Fix segfault in intel PT, by making it follow the 'struct thread' lifetime cycle checking expectations, noticed for instance, when processing perf.data files with Intel PT data using 'perf script' and when exiting 'perf report' (Adrian Hunter) - Fix CFI usage from .eh_frame and .debug_frame, which sometimes requires that we fallback from .eh_frame to .debug_frame in architectures such as PowerPC (Hemant Kumar) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
2016-02-03perf stat: Fix interval output valuesJiri Olsa
We broke interval data displays with commit: 3f416f22d1e2 ("perf stat: Do not clean event's private stats") This commit removed stats cleaning, which is important for '-r' option to carry counters data over the whole run. But it's necessary to clean it for interval mode, otherwise the displayed value is avg of all previous values. Before: $ perf stat -e cycles -a -I 1000 record # time counts unit events 1.000240796 75,216,287 cycles 2.000512791 107,823,524 cycles $ perf stat report # time counts unit events 1.000240796 75,216,287 cycles 2.000512791 91,519,906 cycles Now: $ perf stat report # time counts unit events 1.000240796 75,216,287 cycles 2.000512791 107,823,524 cycles Notice the second value being bigger (91,.. < 107,..). This could be easily verified by using perf script which displays raw stat data: $ perf script CPU THREAD VAL ENA RUN TIME EVENT 0 -1 23855779 1000209530 1000209530 1000240796 cycles 1 -1 33340397 1000224964 1000224964 1000240796 cycles 2 -1 15835415 1000226695 1000226695 1000240796 cycles 3 -1 2184696 1000228245 1000228245 1000240796 cycles 0 -1 97014312 2000514533 2000514533 2000512791 cycles 1 -1 46121497 2000543795 2000543795 2000512791 cycles 2 -1 32269530 2000543566 2000543566 2000512791 cycles 3 -1 7634472 2000544108 2000544108 2000512791 cycles The sum of the first 4 values is the first interval aggregated value: 23855779 + 33340397 + 15835415 + 2184696 = 75,216,287 The sum of the second 4 values minus first value is the second interval aggregated value: 97014312 + 46121497 + 32269530 + 7634472 - 75216287 = 107,823,524 Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: Andi Kleen <ak@linux.intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1454485436-20639-1-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2016-02-03perf hists: Remove perf_hpp__column_(disable|enable)Jiri Olsa
Those functions are no longer needed. They operate over perf_hpp__format array which is now used only as template for dynamic entries.

2016-02-03perf hists: Allocate output sort fieldJiri Olsa
Currently we use static output fields, because we have single global list of all sort/output fields. We will add hists specific sort and output lists in following patches, so we need all format entries to be dynamically allocated. Adding support to allocate output sort field.

2016-02-03perf top: Move UI initialization ahead of sort setupArnaldo Carvalho de Melo
The ui initialization changes hpp format callbacks, based on the used browser. Thus we need this init being processed before setup_sorting. Replica of a patch by Jiri for 'perf report'.

2016-02-03perf hists: Make hpp setup function genericJiri Olsa
Now that we have the 'equal' method implemented for hpp format entries we can ease up the logic in the following functions and make them generic wrt comparing format entries: perf_hpp__setup_output_field perf_hpp__append_sort_keys Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: David Ahern <dsahern@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1453109064-1026-8-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2016-02-03perf hists: Use struct perf_hpp_fmt::idx in perf_hpp__reset_widthJiri Olsa
We are going to add dynamic hpp format fields, so we need to make the 'len' change for the format itself, not in the perf_hpp__format template.

2016-02-03perf hists: Add _idx fields into struct perf_hpp_fmtJiri Olsa

2016-02-03perf hists: Factor output_resort from hists__output_resortJiri Olsa
Currently hists__output_resort() depends on hists based on hists_evsel struct, but we need to be able to sort common hists as well. Cutting out the sorting base sorting code into output_resort function, so it can be reused in following patch.
