Subject: cpu: TrafficGen sinks snoops without complaining
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8c78aa31ea6032d52ecf662f4f11860d995cd5b3;p=gem5.git

cpu: TrafficGen sinks snoops without complaining

To be able to use the TrafficGen in a system with caches we need to
allow it to sink incoming snoop requests. By default the master port
panics, so silently ignore any snoops.
