Subject: [Qemu-devel] [PATCH 0/7] virtio: use MemoryRegionCache for descriptors and rings
Date: Fri, 20 Jan 2017 18:07:50 +0100 [thread overview]
Message-ID: <20170120170757.30308-1-pbonzini@redhat.com> (raw)
Patch posted during 2.8 hard freeze. Quick measurements give a 10%
performance improvement on various virtio-blk benchmarks, but the machine
I used seems to love my patches particularly today!
