Subject: [GIT PULL 00/16] perf/core improvements and fixes
Hi Ingo,
Please consider pulling,
- Arnaldo
The following changes since commit e3b0ac1b7a8a590440a2030e7d10d48c59ab8a2a:
Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2015-10-03 08:20:14 +0200)
are available in the git repository at:

perf tools: Fail properly in case pattern matching fails to find tracepoint (2015-10-05 17:59:50 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Switch the default callchain output mode to 'graph,0.5,caller', to make it
look like the default for other tools, reducing the learning curve for
people used to 'caller' based viewing (Arnaldo Carvalho de Melo)
- Implement column based horizontal scrolling in the hists browser (top, report),
making it possible to use the TUI for things like 'perf mem report' where
there are many more columns than can fit in a terminal (Arnaldo Carvalho de Melo)
- Support sorting by symbol_iaddr with perf.data files produced by
'perf mem record' (Don Zickus)
- Display DATA_SRC sample type bit, i.e. when running 'perf evlist -v' the
"DATA_SRC" wasn't appearing when set, fix it to look like: (Jiri Olsa)
cpu/mem-loads/pp: ...SNIP... sample_type: IP|TID|TIME|ADDR|CPU|PERIOD|DATA_SRC
- Introduce 'P' event modified, meaning 'max precision level, please', i.e.:
$ perf record -e cycles:P usleep 1
Is now similar to:
$ perf record usleep 1
Useful, for instance, when specifying multiple events (Jiri Olsa)
- Make 'perf -v' and 'perf -h' work (Jiri Olsa)
- Fail properly when pattern matching fails to find a tracepoint, i.e.
'-e non:existent' was being correctly handled, with a proper error message
about that not being a valid event, but '-e non:existent*' wasn't,
fix it (Jiri Olsa)
Infrastructure:
- Separate arch specific entries in 'perf test' and add an 'Intel CQM' one
to be fun on x86 only (Matt Fleming)
