Hello,
For some reason, I want to know the memory request source. Is it CPU or GPU. Does anyone know how to do this? thanks.

Hi Lin,
What sort of stats are you looking for? The gem5 stats already give you
information like GPU/CPU L1 and L2 accesses. So if you are just looking
for how many accesses the CPU vs. GPU issue to the caches, looking at these
stats should be sufficient.
Thanks,
Matt

Hi Lin,
If you only want stats, another option is to look at Ruby’s collated stats for cache transitions that would trigger memory requests. These have names like “system.ruby.TCC_Controller.I.RdBlk,” “system.ruby.TCC_Controller.IV.RdBlk,” “system.ruby.TCC_Controller.I.WrVicBlk,” etc. from the GPU. There are similar names in MOESI_AMD_Base-L3cache for CPU.
If you want to determine this during simulation time, that requires a longer response.
