Subject: [PATCH 2/3] perf jevents: Fix period for Intel fixed counters
Date: Fri, 27 Sep 2019 16:35:45 -0700 [thread overview]
Message-ID: <20190927233546.11533-2-andi@firstfloor.org> (raw)
In-Reply-To: <20190927233546.11533-1-andi@firstfloor.org>
From: Andi Kleen <ak@linux.intel.com>
The Intel fixed counters use a special table to override the JSON
information. During this override the period information from
the JSON file got dropped, which results in inst_retired.any
and similar running with frequency mode instead of a period.
Just specify the expected period in the table.
