Subject: [PATCH V2 10/11] cxl/test: Add specific events
Date:   Wed, 30 Nov 2022 16:27:18 -0800

From: Ira Weiny <ira.weiny@intel.com>

Each type of event has different trace point outputs.

Add mock General Media Event, DRAM event, and Memory Module Event
records to the mock list of events returned.
