Subject: [PATCH v10 3/7] perf jevents: Support EventidCode and NodeType
Date:   Mon, 25 Sep 2023 13:57:20 +0800
Message-Id: <1695621444-56530-4-git-send-email-renyu.zj@linux.alibaba.com>
In-Reply-To: <1695621444-56530-1-git-send-email-renyu.zj@linux.alibaba.com>
References: <1695621444-56530-1-git-send-email-renyu.zj@linux.alibaba.com>
Precedence: bulk

The previous code assumes an event has either an "event=" or "config"
field at the beginning. For CMN neither of these may be present, as an
event is typically "type=xx,eventid=xxx".

So add EventidCode and NodeType to support CMN event description.

I compared pmu_event.c before and after compiling with JEVENT_ARCH=all,
they are consistent.
