Under the Source column there are two types of entries: 1) Native refers to aux channel
transactions for DPCD reads and writes for link layer operations and HDCP
transactions; 2)
I2C refers to EDID reads.
You can view details of the transactions by highlighting on a record and then viewing
the Details and Data sections below. The Details section parses out the fields in to
human readable text.
The trace above shows the timestamps in Cumulative mode which shows the time
stamps from the beginning of the trace. To view the time differences between a
