Subject: [PATCH 43/49] perf stat: Add default hybrid events
Date: Mon, 8 Feb 2021 07:25:40 -0800 [thread overview]
Message-ID: <1612797946-18784-44-git-send-email-kan.liang@linux.intel.com> (raw)
In-Reply-To: <1612797946-18784-1-git-send-email-kan.liang@linux.intel.com>
From: Jin Yao <yao.jin@linux.intel.com>
Previously if '-e' is not specified in perf stat, some software events
and hardware events are added to evlist by default.
root@otcpl-adl-s-2:~# ./perf stat -- ./triad_loop
Performance counter stats for './triad_loop':
109.43 msec task-clock # 0.993 CPUs utilized
1 context-switches # 0.009 K/sec
0 cpu-migrations # 0.000 K/sec
105 page-faults # 0.960 K/sec
401,161,982 cycles # 3.666 GHz
1,601,216,357 instructions # 3.99 insn per cycle
200,217,751 branches # 1829.686 M/sec
14,555 branch-misses # 0.01% of all branches
0.110176860 seconds time elapsed
Among the events, cycles, instructions, branches and branch-misses
are hardware events.
One hybrid platform, two events are created for one hardware event.
core cycles,
atom cycles,
core instructions,
atom instructions,
core branches,
atom branches,
core branch-misses,
atom branch-misses
These events will be added to evlist in order on hybrid platform
if '-e' is not set.
Since parse_events() has been supported to create two hardware events
for one event on hybrid platform, so we just use parse_events(evlist,
"cycles,instructions,branches,branch-misses") to create the default
events and add them to evlist.
After:

We can see two events are created for one hardware event.
First one is core event the second one is atom event.
One thing is, the shadow stats looks a bit different, now it's just
'M/sec'.
The perf_stat__update_shadow_stats and perf_stat__print_shadow_stats
need to be improved in future if we want to get the original shadow
stats.
