perf tools: Remove util.h from where it is not needed

2019-09-20T12:19:20+00:00

Check that it is not needed and remove, fixing up some fallout for
places where it was only serving to get something else.

perf dsos: Move the dsos struct and its methods to separate source files

2019-09-01T01:24:10+00:00

So that we can reduce the header dependency tree further, in the process
noticed that lots of places were getting even things like build-id
routines and 'struct perf_tool' definition indirectly, so fix all those
too.

perf tools: Remove debug.h from header files not needing it

2019-08-29T20:38:32+00:00

And fix the fallout, adding it to places that must have it since they
use its definitions.

libperf: Add nr_entries to struct perf_evlist

2019-07-29T21:34:45+00:00

Move nr_entries count from 'struct perf' to into perf_evlist struct.

Committer notes:

Fix tools/perf/arch/s390/util/auxtrace.c case. And also the comment in
tools/perf/util/annotate.h.

perf evsel: Rename struct perf_evsel to struct evsel

2019-07-29T21:34:42+00:00

Rename struct perf_evsel to struct evsel, so we don't have a name clash
when we add struct perf_evsel in libperf.

Committer notes:

Added fixes for arm64, provided by Jiri.

perf annotate TUI browser: Do not use member from variable within its own initialization

2019-05-28T21:37:44+00:00

Some compilers will complain when using a member of a struct to
initialize another member, in the same struct initialization.

For instance:

  debian:8      Debian clang version 3.5.0-10 (tags/RELEASE_350/final) (based on LLVM 3.5.0)
  oraclelinux:7 clang version 3.4.2 (tags/RELEASE_34/dot2-final)

Produce:

  ui/browsers/annotate.c:104:12: error: variable 'ops' is uninitialized when used within its own initialization [-Werror,-Wuninitialized]
                                              (!ops.current_entry ||
                                                ^~~
  1 error generated.

So use an extra variable, initialized just before that struct, to have
the value used in the expressions used to init two of the struct
members.

perf report: Support builtin perf script in scripts menu

2019-03-11T19:33:19+00:00

The scripts menu traditionally only showed custom perf scripts.

Allow to run standard perf script with useful default options too.

- Normal perf script
- perf script with assembler (needs xed installed)
- perf script with source code output (needs debuginfo)
- perf script with custom arguments

Then we automatically select the right options to display the
information in the perf.data file.

For example with -b display branch contexts.

It's not easily possible to check for xed's existence in advance.  perf
script usually gives sensible error messages when it's not available.

pref tools: Add missing map.h includes

2019-02-06T13:00:38+00:00

Lots of places get the map.h file indirectly, and since we're going to
remove it from machine.h, then those need to include it directly, do it
now, before we remove that dep.

perf top: Fix wrong hottest instruction highlighted

2019-01-21T14:29:07+00:00

The annotation line percentage is compared and inserted into the rbtree,
but the percent field of 'struct annotation_data' is an array, the
comparison result between them is the address difference.

This patch compares the right slot of percent array according to
opts->percent_type and makes things right.

The problem can be reproduced by pressing 'H' in perf top annotation view.
It should highlight the instruction line which has the highest sampling
percentage.
