It would be nice if you could provide me and the kvmppc community that=20 patch, because I wanted to modify our tlb handling a bit. If it would be=20 easy enough I would like to test that with a different number of guest=20 tlb entries too to see how big the impact of such a change would be to=20 our shadow tlb management. --=20 Gr=FCsse / regards,=20 Christian Ehrhardt IBM Linux Technology Center, Open Virtualization
