Subject: [PATCH v8 3/9] perf vendor events arm64: Add common topdown L1 metrics
Date:   Tue, 17 Jan 2023 15:29:27 +0800
Message-Id: <1673940573-90503-4-git-send-email-renyu.zj@linux.alibaba.com>
In-Reply-To: <1673940573-90503-1-git-send-email-renyu.zj@linux.alibaba.com>
References: <1673940573-90503-1-git-send-email-renyu.zj@linux.alibaba.com>
Precedence: bulk

The metrics of topdown L1 are from ARM sbsa7.0 platform design doc[0],
D37-38, which are standard. So put them in the common file sbsa.json of
arm64, so that other cores besides n2/v2 can also be reused.
