Hi Avi, Marcelo, This patchset support pte prefetch when intercepted guest #PF, the aim is to reduce guest #PF which can be intercepted by VMM. If we meet any failure in the prefetch path, we will exit it and not try other ptes to avoid become heavy path. During my performance test, under EPT enabled case, unixbench shows the performance improved ~1.2%, user EPT disable case, unixbench shows the performance improved ~3.6% -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
