Hi Brad,
Can you elaborate on last item - Consolidate under a single stats
infrastructure and stats output file.

Hi Nilay,
Please excuse the slow reply. Here is my perspective of what is left to for
Ruby.
Right now I have internal patches that re-enable the cache warmup tracing
capability, remove recycle requests, and incorporate several other bug fixes.
I plan to soon add uncacheable access support as well, because I believe that
is essential for cache warmup tracing to fully support data values. I won't
bore you on the specific details here, but I'm happy to go into them if you're
interested. Once I find the time to clean up these patches, I'll send them out
for review. I'm hoping for mid-July. Also Arka is currently working on
supporting hierarchical designs, so I think we have that item covered as well.
Finally, another item that we at AMD are interested in completing is
reintegrating the prefetchers, though I'm not sure if that will happen soon.
Therefore, the remaining items to do are as follows:
- Ruby supplying data to M5 CPU models
- To me this is the 500 lb Gorilla still left in the room. The key problem is
that Ruby/SLICC doesn't have a good interface to support functional accesses
during execution. I have some ideas of how to make them work, but I would
definitely like to discuss them with the great dev community before
implementing them. If you're interested, I would be happy to go into the
details.
- Performance fixes
- The PerfectSwitch is a prime target for optimization. However, before we
re-architect it, we should determine whether we want to just deprecate the
simple network and use an optimized version of Garnet instead.
- Consolidate under a single stats infrastructure and stats output file.
...Of course there is the Bochs work as well, but that isn't necessarily Ruby
related.
Others, please feel free to add to the list.
Brad
