Pull perf updates from Ingo Molnar:
"Lots of activity:
211 files changed, 8328 insertions(+), 4116 deletions(-)
most of it on the tooling side.
Main changes:
* ftrace enhancements and fixes from Steve Rostedt.
* uprobes fixes, cleanups and preparation for the ARM port from Oleg
Nesterov.
* UAPI fixes, from David Howels - prepares the arch/x86 UAPI
transition
* Separate perf tests into multiple objects, one per test, from Jiri
Olsa.
* Make hardware event translations available in sysfs, from Jiri
Olsa.
* Fixes to /proc/pid/maps parsing, preparatory to supporting data
maps, from Namhyung Kim
* Implement ui_progress for GTK, from Namhyung Kim
* Add framework for automated perf_event_attr tests, where tools with
different command line options will be run from a 'perf test', via
python glue, and the perf syscall will be intercepted to verify
that the perf_event_attr fields set by the tool are those expected,
from Jiri Olsa
* Add a 'link' method for hists, so that we can have the leader with
buckets for all the entries in all the hists. This new method is
now used in the default 'diff' output, making the sum of the
'baseline' column be 100%, eliminating blind spots.
* libtraceevent fixes for compiler warnings trying to make perf it
build on some distros, like fedora 14, 32-bit, some of the warnings
really pointed to real bugs.
* Add a browser for 'perf script' and make it available from the
report and annotate browsers. It does filtering to find the
scripts that handle events found in the perf.data file used. From
Feng Tang
* perf inject changes to allow showing where a task sleeps, from
Andrew Vagin.
* Makefile improvements from Namhyung Kim.
* Add --pre and --post command hooks in 'stat', from Peter Zijlstra.
* Don't stop synthesizing threads when one vanishes, this is for the
existing threads when we start a tool like trace.
* Use sched:sched_stat_runtime to provide a thread summary, this
produces the same output as the 'trace summary' subcommand of
tglx's original "trace" tool.
* Support interrupted syscalls in 'trace'
* Add an event duration column and filter in 'trace'.
* There are references to the man pages in some tools, so try to
build Documentation when installing, warning the user if that is
not possible, from Borislav Petkov.
* Give user better message if precise is not supported, from David
Ahern.
* Try to find cross-built objdump path by using the session
environment information in the perf.data file header, from Irina
Tirdea, original patch and idea by Namhyung Kim.
* Diplays more output on features check for make V=1, so that one can
figure out what is happening by looking at gcc output, etc. From
Jiri Olsa.
* Add on_exit implementation for systems without one, e.g. Android,
from Bernhard Rosenkraenzer.
* Only process events for vcpus of interest, helps handling large
number of events, from David Ahern.
* Cross compilation fixes for Android, from Irina Tirdea.
* Add documentation on compiling for Android, from Irina Tirdea.
* perf diff improvements from Jiri Olsa.
* Target (task/user/cpu/syswide) handling improvements, from Namhyung
Kim.
* Add support in 'trace' for tracing workload given by command line,
from Namhyung Kim.
* ... and much more."
