Subject[PATCH V4 3/3] perf,test: test cpu topology
Message-ID<q418d-1tL-3@gated-at.bofh.it>
From: Jiri Olsa <jolsa@kernel.org>

This patch test cpu core_id and socket_id which are stored in perf_env.

Changes since jirka's original version
 - Use pr_debug to replace fprintf
 - Add date_size to avoid warning
 - Introduce cpu_map, and compare core_id and socket_id
   between cpu_map and perf_env

Changes since V2:

Humm, two questions:

Since you changed it that much, wouldn't be better to give you the
authorship while still giving credit to Jiri for the original version?
Something like:

Based-on-a-patch-by: Jiri Olsa

[acme@zoo linux]$ git log | grep Based-on-patch-by: | wc -l
61
[acme@zoo linux]$ git log | grep Based-on-a-patch-by: | wc -l
4
[acme@zoo linux]$ 

But then you need to resubmit this anyway, as you forgot to do the:

 git add tools/perf/tests/topology.c

:-)

Jiri, are you OK with that?
