Subject: [PATCH AUTOSEL 4.9 32/33] perf pmu-events: Fix missing "cpu_clk_unhalted.core" event
Date: Tue, 13 Aug 2019 22:23:22 -0400
Message-ID: <20190814022323.17111-32-sashal@kernel.org> (raw)
In-Reply-To: <20190814022323.17111-1-sashal@kernel.org>

From: Jin Yao <yao.jin@linux.intel.com>

[ Upstream commit 8e6e5bea2e34c61291d00cb3f47560341aa84bc3 ]

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 the 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
