This implements a virtio simulator: - adds stubs for enough support functions to compile virtio ring in userspace. - Adds a stub vhost based module this can talk to. This should help us decide things like which ring layout works best. Communication is currently done using an eventfd descriptor. This means there's a shared spinlock there: what I would like to do in the future, is run

Here's a patchset to update tools/virtio with changes in 3.8, as well as the proposed API extension. Useful to see whether the extra level of indirection adds measureable overhead. I will upstream at least patch 1 soon. Michael S. Tsirkin (2): tools/virtio: fix build for 3.8 tools/virtio: update for the new virtio API drivers/vhost/test.c | 4 +++- tools/virtio/Makefile

From: Nicholas Bellinger <nab at linux-iscsi.org> Hi MST, Greg-KH & Co, The following is -v4 of the in-flight TCM vhost fabric driver for-3.6 code. This series has been rebased into target-pending.git/for-next-merge this evening, and the changelog over the last days from v3 -> v4 has been: *) Rename vhost_vring_target -> vhost_scsi_target (mst + nab) *) Use TRANSPORT_IQN_LEN

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.
