Hi, I've noticed than when you run gem5 using X86 iSA there is a huge bottleneck in SQ due to TSO implementation as only one store is allowed to be in flight. As a consequence old stores that are waiting to access memory and that aren't present in ROB saturate SQ structure.
I think that these old stores should be inserted in another structure not to saturate SQ as what i see in results files is that cpu is stalled half of simulation cause SQ is full. Has anybody experimented what i describe? Thanks, Adrian. _______________________________________________ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
