Great news, Devin. If you create a changeset for these we’d really appreciate if you could post it to Gerrit so we can merge it into my branch.

I think I've got it working now for VIPER and the TCPs. I'll double check that the numbers make sense after a few runs. Thanks!

What is missing is an action in the sm file which updates the cache stats, and calls to that action from the appropriate transitions. You can see an example of how the stats can be updated in another sm file, like MOESI_AMD_Base-CorePair.sm Tony From: gem5-users <gem5-users-boun...@gem5.org<mailto:gem5-users-boun...@gem5.org>> On Behalf Of Devlafford . Sent: Tuesday, April 16, 2019 3:13 PM To: gem5-users@gem5.org<mailto:gem5-users@gem5.org> Subject: [gem5-users] AMD APU Cache Hit Statistics Hello, I am trying to use AMD’s APU model for gem5 found at https://gem5.googlesource.com/amd/gem5/+/agutierr/master-gcn3-staging to perform a sensitivity analysis of cache behavior on various GPU workloads, but it doesn’t look like cache statistics are being tracked correctly. Looking in the stats file at system.ruby.tcp_cntrl0.L1cache.demand_accesses shows that there are zero cache accesses, and the same goes for the other CUs’ TCPs. Should these statistics be tracked? I am running the Floyd-Warshall benchmark from the Pannotia Benchmark set with the 512 vertex and 64k edge graph provided in the dataset, and I wouldn’t imagine that this entire dataset fits into the register file. Any ideas for what I’m doing wrong? I was directed by Matt Sinclair to ask Tony Gutierrez specifically about this.
