Subject: [PATCH 0/6] KVM: MMU: support pte prefetch when intercepted guest #PF
Date: Tue, 15 Jun 2010 10:46:12 +0800	[thread overview]
Message-ID: <4C16E974.8000304@cn.fujitsu.com> (raw)

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%
