5.17 Resources
Events in Recording Rules are based on Resources. There are three types of Resources.
They are Packet Match Resources, Basic Resources and Payload Match Resources.
5.17.1 Packet Match Resource
Packet Match Resources are for the TLP, DLLP, TS1 and TS2 events as well as storage
protocol trigger options AHCI Register and NVMe Register. A Packet Match Resource
allows you to define not only packets but it also allows you to define each specific bit in a
packet. In the Packet Match resource you can define the exact layout to the bit level so
that the Analyzer can match the exact pattern that applies to a TLP, DLLP, TS1 or TS2
event.
To set a Packet Match Resource, click on the New Event button and select any of the
options. In this case we have selected DLLP: InitFC1. The DLLP: InitFC1 displays in the
Available Events panel. Double‐click on the DLLP: InitFC1 to select the specific fields and
go to the Layout tab to change the pre‐defined bits.
