Subject: [PATCH RFC v3 1/6] cxl/trace: Remove uuid from event trace known events
Date: Wed, 01 Nov 2023 14:11:18 -0700 [thread overview]
Message-ID: <20230601-cxl-cper-v3-1-0189d61f7956@intel.com> (raw)
In-Reply-To: <20230601-cxl-cper-v3-0-0189d61f7956@intel.com>
The uuid printed in the well known events is redundant. The uuid
defines what the event was.
Remove the uuid from the known events and only report it in the generic
event as it remains informative there.
