This patch introduces a guest TLB flush on every NPF exit in KVM.
This fixes
random segfaults and #UD exceptions in the guest seen under some
workloads
(e.g. long running compile workloads or tbench). A kernbench run with
and
without that fix showed that it has a slowdown lower than 0.5%
hm. tbench doesn't allocate memory, so there shouldn't be any npt
faults. I don't see how this can make a difference.
It can only change something if X is started and we're tracking writes
to the framebuffer. Is this the case?
I fixed a missing flush in this area. Does it help? (I doubt it). Can
you post instructions on how to reproduce?
