b821c7325 perf diff: Start moving to support matching more than two hists ... Browse Code »

We want to match more than two hists, so that we can match more than two
perf.data files and moreover, match hist_entries (buckets) in multiple
events in a group.

So the "baseline"/"leader" will instead of a ->pair pointer, use a
list_head, that will link to the pairs and hists__match use it.

Following that perf_evlist__link will link the hists in its evsel
groups.

ff6f7778a perf tools: Don't try to lookup objdump for live mode ... Browse Code »

Arnaldo reported that annotation during perf top resulted in a segfault.
It was because the env->arch was NULL and we don't set it for a live
session. In fact, no need to look up objdump in this case since we can
use system's default (native) objdump.

David reported that current perf report refused to run on a data file
captured from a different machine because of objdump.

Since the objdump tools won't be used unless annotation was requested,
checking its presence at init time doesn't make sense.

9783adf77 perf tools: Introduce struct hist_browser_timer ... Browse Code »

Currently various hist browser functions receive 3 arguments for
refreshing histogram but only used from a few places. Also it's only
for perf top command so that it can be NULL for other (and probably
most) cases. Pack them into a struct in order to reduce number of those
unused arguments.

This is a mechanical change and does not intend a functional change.

David reported that perf report for i686 target data on x86_64 host
failed to work because it tried to find out cross-compiled objdump.

However objdump for x86_64 is compatible to i686 so that it doesn't need
to do it at all. To prevent similar artifacts, normalize arch name when
comparing host and file architectures.

The test attr suite is run only if it's run under perf source directory,
or tests are found in installed path.

Otherwise tests are omitted (notification is displayed) and finished as
successful.

52502bf20 perf tests: Add framework for automated perf_event_attr tests ... Browse Code »

The idea is run perf session with kidnapping sys_perf_event_open
function. For each sys_perf_event_open call we store the perf_event_attr
data to the file to be checked later against what we expect.

You can run this by:
$ python ./tests/attr.py -d ./tests/attr/ -p ./perf -v

v2 changes:
- preserve errno value in the hook

c77d8d703 perf browser: Don't show scripts menu for 'perf top' ... Browse Code »

As 'perf top' has no data files to run scripts against. Also add a
is_report_browser() helper function to judge whether the running browser
is for 'perf report'.
