Subject: [PATCH 6.6 197/244] perf vendor events arm64: AmpereOne: Add missing DefaultMetricgroupName fields
Date: Mon, 11 Dec 2023 19:21:30 +0100	[thread overview]
Message-ID: <20231211182054.781810722@linuxfoundation.org> (raw)
In-Reply-To: <20231211182045.784881756@linuxfoundation.org>

6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ilkka Koskinen <ilkka@os.amperecomputing.com>

[ Upstream commit 90fe70d4e23cb57253d2668a171d5695c332deb7 ]

AmpereOne metrics were missing DefaultMetricgroupName from metrics with
"Default" in group name resulting perf to segfault. Add the missing
field to address the issue.

Fixes: 59faeaf80d02 ("perf vendor events arm64: Fix for AmpereOne metrics")
