My question is simple if there are two packets wants to access L1 cache in a system of 2 level cache and cpu is o3. Will packet 2 has to wait for packet 1 to get its response(packet 1) from L2 in case of L1 cache miss and L2 cache hit? What happen if its L2 miss?

What you do, is create flags in src/mem/packet.hh for various cache levels. Whenever you hit in L2, you can set the L2flag in response pkt. And if it is misses in L2, set main memory flag in response pkt, as you are sure you will get data from main memory. Here we are assuming it’s a single core

Hello Nazish, If you are using classic memory, edit src/mem/cache/base.cc file’s recvTimingReq function. You can access the old data through blk->data and the new data by pkt->getdata(this you need to search in src/mem/packet.hh, I may have made mistake in writing correct name of the function).

With that said For x86 O3CPU, the multi program workload simulation is also broken. So basically one can not multi core simulation using x86 O3CPU with and without SMT. Also, to all developers who push commit to gem5, please do thorough testing as both of this support was working in older
