Sounds like useful data, but is it a suitable topic for LSF-MM?
What open questions etc is it raising?
mTHP is new functionality that will require additional work to support
more use cases. It is also unclear at this point in what usecases mTHP is
useful and where no benefit can so far be seen. Also the effect of
coalescing multiple PTE entries into one TLB entry is new to MM
(CONT_PTE).
Ultimately it would be useful to have mTHP support also provide larger
blocksize capabilities for filesystem etc etc. mTHP needs to mature and an
analysis of the arguable a bit experimental state of affairs can help a
lot in getting there.
Right, something like that (open items, missed use cases, requirements,
ideas, etc,.) would be a better (good!) fit.
Pure benchmark results, analysis and recommendations are great. But
likely a better fit for a (white) paper, blog post,
less-discussion-focused conference.
