Subject: [PATCH v4 4/4] perf vendor events: Add metrics for Arm CMN
Date: Sun, 23 Jul 2023 16:21:53 +0800 [thread overview]
Message-ID: <1690100513-61165-5-git-send-email-renyu.zj@linux.alibaba.com> (raw)
In-Reply-To: <1690100513-61165-1-git-send-email-renyu.zj@linux.alibaba.com>
Add JSON metrics for Arm CMN. Currently just add part of CMN PMU
metrics which are general and compatible for any SoC with CMN-ANY.
