[PATCH V2 10/11] cxl/test: Add specific events

From: ira . weiny
Date: Wed Nov 30 2022 - 19:28:14 EST


From: Ira Weiny <ira.weiny@xxxxxxxxx>

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.

Reviewed-by: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
