Hi Scott,
I just discussed with Hollis about shadow tlb management in the
hypervisor and he mentioned that you already have a patch that lets the
guest use more tlb entries than it would have on bare metal hardware and
therefore allow to handle more tlb misses in the host because the shadow
tlb already holds that information.
It would be nice if you could provide me and the kvmppc community that
patch, because I wanted to modify our tlb handling a bit. If it would be
easy enough I would like to test that with a different number of guest
tlb entries too to see how big the impact of such a change would be to
our shadow tlb management.
