Hi everyone,
As we already know, a "Read miss" at the last cache level (LLC) means that the desired block in the LLC for reading was
not found. Consequently, it is necessary to locate a victim block and copy the desired block from the main memory to the
victim block's location in the last cache level.
I want to see the data content of the blocks that were brought to the last level of the cache due to a read miss from
the main memory. However, I am unsure where the Read Miss operation is implemented. Based on my research, it appears
that the function:
CacheBlk* BaseCache::handleFill(PacketPtr pkt, CacheBlk *blk, PacketList
&writebacks, bool allocate)
maybe helpful in this regard.
I would greatly appreciate any suggestions or guidance on how to effectively validate my findings. For your information,
I am utilizing a classic cache configuration and an O3 CPU type.
Thank you for your attention to this matter, and I eagerly look forward to your
guidance.
If you're running a timing model, the packet will arrive with
a RecvTimingResp call. The code for that function will look
at the nature of the response and possibly load data into a
cache block. That's where I would look.
Best wishes - EM
