toplev: Info_Bottlenecks reports negative Scaled_Slots on SKX
- @aayasin TMA problem?
e.g. on SKL
./toplev --metrics -l3 -q ./workloads/GITGREP 2>&1 | grep Bottleneck C0-T0 Info.Bottleneck Mispredictions Scaled_Slots -1.85 [ 1.0%] C0-T0 Info.Bottleneck Irregular_Overhead Scaled_Slots -7.60 [ 1.0%] ...
Interestingly it goes away with --single-thread so it might be a SMT issue?
