perf kvm: Fix subcommand matching error
...
Currently the 'diff', 'top', 'buildid-list' and 'stat' perf commands use
strncmp() to match subcommands. As a result, matching does not meet
expectation.
For example:
# perf kvm diff1234
# Event 'cycles'
#
# Baseline Delta Abs Shared Object Symbol
# ........ ......... ............. ......
#
# Event 'dummy:HG'
#
# Baseline Delta Abs Shared Object Symbol
# ........ ......... ............. ......
#
# echo $?
0
#
Invalid information should be returned, but success is actually returned.
Solution: Use strstarts() to match subcommands.
After:
# perf kvm diff1234
Usage: perf kvm [<options>] {top|record|report|diff|buildid-list|stat}
-i, --input <file> Input file name
-o, --output <file> Output file name
-v, --verbose be more verbose (show counter open errors, etc)
--guest Collect guest os data
--guest-code Guest code can be found in hypervisor process
--guestkallsyms <file>
file saving guest os /proc/kallsyms
--guestmodules <file>
file saving guest os /proc/modules
--guestmount <directory>
guest mount directory under which every guest os instance has a subdir
--guestvmlinux <file>
file saving guest os vmlinux
--host Collect host os data
# echo $?
129

perf tools: Enhance the matching of sub-commands abbreviations
...
We support short command 'rec*' for 'record' and 'rep*' for 'report' in
lots of sub-commands, but the matching is not quite strict currnetly.
It may be puzzling sometime, like we mis-type a 'recport' to report but
it will perform 'record' in fact without any message.
To fix this, add a check to ensure that the short cmd is valid prefix
of the real command.
Committer testing:
[root@quaco ~]# perf c2c re sleep 1
Usage: perf c2c {record|report}
-v, --verbose be more verbose (show counter open errors, etc)
# perf c2c rec sleep 1

Also add mmap.h to the places using it but previously getting it

Add missing pthread.h to evlist.h, as it has a pthread_t struct member
and was getting the header via mmap.h.
Noticed while processing a Jiri's libperf batch touching mmap.h, where
almost everything gets rebuilt because evlist.h is so popular, so cut
down't this rebuild the world party.

Test Results:

$
After Fix:
$ perf c2c report -input
failed to open nput: No such file or directory
$ echo $?
254
$
Committer notes:
Fix 'perf tests topology' case, where we use that TEST_ASSERT_VAL(...,
session), i.e. we need to pass zero in case of failure, which was the
case before when NULL was returned by perf_session__new() for failure,
but now we need to negate the result of IS_ERR(session) to respect that
TEST_ASSERT_VAL) expectation of zero meaning failure.

perf kvm: Add arch neutral function to choose event for perf kvm record
...
'perf kvm record' uses 'cycles'(if the user did not specify any event)
as the default event to profile the guest.
This will not provide any proper samples from the guest incase of
powerpc architecture, since in powerpc the PMUs are controlled by the
guest rather than the host.
Patch adds a function to pick an arch specific event for 'perf kvm
record', instead of selecting 'cycles' as a default event for all
architectures.
For powerpc this function checks for any user specified event, and if
there isn't any it returns invalid instead of proceeding with 'cycles'
event.

definitions in the header file under the conditional inclusion `#ifdef
HAVE_KVM_STAT_SUPPORT`.
This helps to define other 'perf kvm' related function prototypes in
kvm-stat header file, which may not need kvm-stat support.

perf tools: Move event synthesizing routines to separate header
...
Those are the only routines using the perf_event__handler_t typedef and
are all related, so move to a separate header to reduce the header
dependency tree, lots of places were getting event.h and even stdio.h,
limits.h indirectly, so fix those as well.

perf tools: Remove needless evlist.h include directives

Remove the last unneeded use of cache.h in a header, we can check where
it is really needed, i.e. we can remove it and be sure that it isn't
being obtained indirectly.
This is an old file, used by now incorrectly in many places, so it was
providing includes needed indirectly, fixup this fallout.

libperf: Move perf_event_attr field from perf's evsel to libperf's perf_evsel
...
Move the perf_event_attr struct fron 'struct evsel' to 'struct perf_evsel'.
Committer notes:
Fixed up these:
tools/perf/arch/arm/util/auxtrace.c
tools/perf/arch/arm/util/cs-etm.c
tools/perf/arch/arm64/util/arm-spe.c
tools/perf/arch/s390/util/auxtrace.c
tools/perf/util/cs-etm.c
Also
cc1: warnings being treated as errors
tests/sample-parsing.c: In function 'do_test':
tests/sample-parsing.c:162: error: missing initializer
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 = {
+ . attr = {
+ .sample_type = sample_type,
+ .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.

perf data: Add global path holder
...
Add a 'path' member to 'struct perf_data'. It will keep the configured
path for the data (const char *). The path in struct perf_data_file is
now dynamically allocated (duped) from it.
This scheme is useful/used in following patches where struct
perf_data::path holds the 'configure' directory path and struct
perf_data_file::path holds the allocated path for specific files.
Also it actually makes the code little simpler.

perf tools: Allow specifying proc-map-timeout in config file
...
The default timeout of 500ms for parsing /proc/<pid>/maps files is too
short for profiling many of our services.
This can be overridden by passing --proc-map-timeout to the relevant
command but it'd be nice to globally increase our default value.
This patch permits setting a different default with the
core.proc-map-timeout config file parameter.
