- Fix wrong jump arrow in systems with branch records with cycles,
i.e. Intel's >= Skylake (Jin Yao)
- Fix 'perf record --per-thread' problem introduced when
implementing 'perf stat --per-thread (Jin Yao)
- Use arch__compare_symbol_names() to fix 'perf test vmlinux',
that was using strcmp(symbol names) while the dso routines
doing symbol lookups used the arch overridable one, making
this test fail in architectures that overrided that function
with something other than strcmp() (Jiri Olsa)
- Add 'perf script --show-round-event' to display
PERF_RECORD_FINISHED_ROUND entries (Jiri Olsa)
- Fix dwarf unwind for stripped binaries in 'perf test' (Jiri Olsa)
- Use ordered_events for 'perf report --tasks', otherwise we may get
artifacts when PERF_RECORD_FORK gets processed before PERF_RECORD_COMM
(when they got recorded in different CPUs) (Jiri Olsa)
- Add support to display group output for non group events, i.e.
now when one uses 'perf report --group' on a perf.data file
recorded without explicitly grouping events with {} (e.g.
"perf record -e '{cycles,instructions}'" get the same output
that would produce, i.e. see all those non-grouped events in
multiple columns, at the same time (Jiri Olsa)
- Skip non-address kallsyms entries, e.g. '(null)' for !root (Jiri Olsa)
- Kernel maps fixes wrt perf.data(report) versus live system (top)
(Jiri Olsa)
- Fix memory corruption when using 'perf record -j call -g -a <application>'
followed by 'perf report --branch-history' (Jiri Olsa)
- ARM CoreSight fixes (Mathieu Poirier)
- Add inject capability for CoreSight Traces (Robert Waker)
- Update documentation for use of 'perf' + ARM CoreSight (Robert Walker)
- Man pages fixes (Sangwon Hong, Jaecheol Shin)
- Fix some 'perf test' cases on s/390 and x86_64 (some backtraces
changed with a glibc update) (Thomas Richter)
- Add detailed CPUID info in the 'perf.data' headers for s/390 to
then use it in 'perf annotate' (Thomas Richter)
- Add '--interval-count N' to 'perf stat', to use with -I, i.e.
'perf stat -I 1000 --interval-count 2' will show stats every
1000ms, two times (yuzhoujian)
- Add 'perf stat --timeout Nms', that will run for that many
milliseconds and then stop, printing the counters (yuzhoujian)
- Fix description for 'perf report --mem-modex (Andi Kleen)
- Use a wildcard to remove the vfs_getname probe in the
'perf test' shell based test cases (Arnaldo Carvalho de Melo)
