Subject: [PATCH 4.19 064/149] perf jevents: Fix period for Intel fixed counters
From: Andi Kleen <ak@...ux.intel.com>
[ Upstream commit 6bdfd9f118bd59cf0f85d3bf4b72b586adea17c1 ]
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.
