Pqos tool doesn't support CPUs with hybrid architecture #272

Open rstorozh opened 2 months ago

rstorozh commented 2 months ago

Pqos tool doesn't currently support client-level CPUs like Alder Lake and upcoming. Hybrid architecture means that a system has both E-cores and P-cores on board simultaneously. Those type of cores have different L2 cache capacities. Pqos tool doesn't distinguish between core types which could lead to L2 underutilization or wrong behaviour. The background for hybrid architectures described here: https://github.com/intel/intel-cmt-cat/wiki/Hybrid-architectures
