Subject: [PATCH] perf pmu-events: Fix the missing "cpu_clk_unhalted.core"
Date: Mon, 29 Jul 2019 15:27:55 +0800 [thread overview]
Message-ID: <20190729072755.2166-1-yao.jin@linux.intel.com> (raw)
The events defined in pmu-events JSON are parsed and added into
perf tool. For fixed counters, we handle the encodings between
JSON and perf by using a static array fixed[].
But the fixed[] has missed an important event "cpu_clk_unhalted.core".
For example, on tremont platform,
[root@localhost ~]# perf stat -e cpu_clk_unhalted.core -a
event syntax error: 'cpu_clk_unhalted.core'
\___ parser error
With this patch, the event cpu_clk_unhalted.core can be parsed.
[root@localhost perf]# ./perf stat -e cpu_clk_unhalted.core -a -vvv
