As they are 'struct evsel' methods or related routines, not part of
tools/lib/perf/, aka libperf, to whom the perf_ prefix belongs.

Add perf_evlist__first()/last() functions to libperf, as internal

Only a 'struct perf_cmp_map' forward allocation is necessary, fix the
places that need the header but were getting it indirectly, by luck,

Committer notes:
Fixed up these:

tools/perf/arch/s390/util/auxtrace.c

Also
cc1: warnings being treated as errors
tests/sample-parsing.c: In function 'do_test':

tests/sample-parsing.c:162: error: (near initialization for 'evsel.core.cpus')
struct evsel evsel = {
.needs_swap = false,
- .core.attr = {
- .sample_type = sample_type,
- .read_format = read_format,
+ .core = {

+ .read_format = read_format,
+ },
[perfbuilder@a70e4eeb5549 /]$ gcc --version |& head -1
gcc (GCC) 4.4.7
Also we don't need to include perf_event.h in
tools/perf/lib/include/perf/evsel.h, forward declaring 'struct
perf_event_attr' is enough. And this even fixes the build in some
systems where things are used somewhere down the include path from
perf_event.h without defining __always_inline.

Getting unwieldly long, for this app domain should be descriptive enough
and the use of __ to separate the class from the method names should
help with avoiding clashes with other code bases.

Using struct perf_record_opts to specify how to configure the evsel
perf_event_attrs.
This gets top closer to record in the way it sets up evsels, with the
aim of sharing more and more to the point that both will be a single
utility.
In this direction top now uses the same callchain option parsing as
record and that brings DWARF callchains to top, something that was
already available for record.

This actually fixes several problems we had in the old 'perf top':
1. Unresolved symbols not show, limitation that came from the old
"KernelTop" codebase, to solve it we would need to do changes
that would make sym_entry have most of the hist_entry fields.
2. It was using the number of samples, not the sum of sample->period.
And brings the --sort code that allows us to have all the views in
'perf report', for instance:
[root@emilia ~]# perf top --sort dso
PerfTop: 5903 irqs/sec kernel:77.5% exact: 0.0% [1000Hz cycles], (all, 8 CPUs)
------------------------------------------------------------------------------
31.59% libcrypto.so.1.0.0
21.55% [kernel]
18.57% libpython2.6.so.1.0
7.04% libc-2.12.so
6.99% _backend_agg.so
4.72% sshd
1.48% multiarray.so
1.39% libfreetype.so.6.3.22
1.37% perf
0.71% libgobject-2.0.so.0.2200.5
0.53% [tg3]
0.48% libglib-2.0.so.0.2200.5
0.44% libstdc++.so.6.0.13
0.40% libcairo.so.2.10800.8
0.38% libm-2.12.so
0.34% umath.so
0.30% libgdk-x11-2.0.so.0.1800.9

^C
All the filter lists can be used as well: --dsos, --comms, --symbols,
etc.
The 'perf report' TUI is also reused, being possible to apply all the
zoom operations, do annotation, etc.
This change will allow multiple simplifications in the symbol system as
well, that will be detailed in upcoming changesets.

Passing multiple events might force out information about pid/tid/cpu.
Attached patch leaves 30 characters for this info at the expense of the
events' names.

The snprintf function returns number of printed characters even if it
cross the size parameter. So passing enough events via '-e' parameter
will cause segmentation fault.
It's reproduced by following command:
perf top -e `perf list | grep Tracepoint | awk -F'[' '\
{gsub(/[[:space:]]+/,"",$1);array[FNR]=$1}END{outputs=array[1];\
for (i=2;i<=FNR;i++){ outputs=outputs "," array[i];};print outputs}'`
Attached patch is adding SNPRINTF macro that provides the overflow check
and returns actuall number of printed characters.

From the sym_entry struct, struct symbol already has this field.

Disabled by default as there are features found in the stdio based one
that aren't implemented, like live annotation, filtering knobs data
entry.
Annotation hopefully will get somehow merged with the 'perf annotate'
code.
To use it:
perf top --tui

Paving the way for a slang browser a la 'perf report --tui'.
