This is a very valuable link. Thanks a lot for sharing.
Aaron and I are particular interesting to the huge page (both hugetlb
and THP) support for gmem_fd (per our testing, at least 10%+ performance
gain with it with TDX for many workloads). We will monitor the linux-mm
for such kind of discussion. I am wondering whether it's possible that
you can involve Aaron and me if the discussion is still open but not on
the mailing list (I suppose you will be included always for such kind of
discussion). Thanks.
Regards
Yin, Fengwei
