From: Asias He <asias.hejun at gmail.com> This patch is based on Sasha's 'kvm tools: Add support for virtio-mmio' patch. ioeventfds support is added which was missing in the previous one. VQ size/align is still not supported. It adds support for the new virtio-mmio transport layer added in 3.2-rc1. The purpose of this new layer is to allow virtio to work on systems which don't necessarily support PCI, such as embedded s...

Currently, vhost-net is the only consumer of vhost infrastructure. So vhost infrastructure and vhost-net driver are in a single module. Separating this as a vhost.ko module and a vhost-net.ko module makes it is easier to share code with other vhost drivers, e.g. vhost-blk.ko, tcm-vhost.ko.

Hi folks, [I am resending to fix the broken thread in the previous one.] This patchset adds vhost-blk support. vhost-blk is a in kernel virito-blk device accelerator. Compared to userspace virtio-blk implementation, vhost-blk gives about 5% to 15% performance improvement. Asias He (5): aio: Export symbols and struct kiocb_batch for in kernel aio usage eventfd: Export symbol

Get blktap2 running on pvops. This mainly adds eventfd support to the userland code. Based on some prior cleanup to tapdisk-queue and the server object. We had most of that in XenServer for a while, so I kept it stacked. 1. Clean up IPC and AIO init in tapdisk-server. [I think tapdisk-ipc in blktap2 is basically obsolete. Pending a later patch to remove it?] 2. Split tapdisk-queue into
