Subject: [PATCH 2/4] perf vendor events arm64: AmpereOne: Mark affected STALL_* events impacted by errata
Date: Thu, 3 Aug 2023 14:13:29 -0700 [thread overview]
Message-ID: <20230803211331.140553-3-ilkka@os.amperecomputing.com> (raw)
In-Reply-To: <20230803211331.140553-1-ilkka@os.amperecomputing.com>
Per errata AC03_CPU_29, STALL_SLOT_FRONTEND, STALL_FRONTEND, and STALL
events are not counting as expected. The follow up metrics patch will
include correct way to calculate the impacted events.
