Subject: [PATCH 0/8] KVM: minor cleanups and optimizations
Date: Thu, 30 Aug 2012 01:30:12 +0200 [thread overview]
Message-ID: <1346283020-22385-1-git-send-email-minipli@googlemail.com> (raw)
Hi Avi, Marcelo
this patch series implements a few micro optimizations for the x86 KVM
code base. The two major changes are constification of variables and an
optimization for the SSE emulation. The former gives the compiler more
opportunities for optimizations and ensures the r/o data is not put in
a cache line together with data that gets written to. The latter should
speed up the emulation of SSE register moves as the aligned variant of
MOVDQ has lower latencies and higher throughput than the unaligned one.
Regards,
