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

Hi, This patchset allows vhost to be used with legacy virtio when guest and host have a different endianness. It is a complete rework of my initial post. Patches 1 to 5 are preliminary work: we move the endianness check out of all memory accessors to separate functions. Patch 6 changes the semantics of the accessors so that they have explicit big endian support. Patch 7 brings the cross-endian

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
