- Share VFIO container fd instead of group fd to QEMU;
- Extend libvhost-user and vhost-user-bridge for testing;
Tiwei Bie (4):
vfio: support creating VFIOContainer directly
vhost-user: support programming VFIO
his case, backend won't need
to close any fd. But there is one problem that, it's
hard to unmap the old mappings, especially when QEMU
crashes. Do you have any suggestions? Thanks!

With this feature negotiated, vhost-user backend can register

The idea of this patch is to let QEMU push all the IOTLBs
to vhost-user backend without waiting for the queries from
the backend

This macro isn't used by any VFIO code. And its name is
too generic. The vfio-common.h (in include/hw/vfio) can
be included by other modules in QEMU. It can introduce

groupfd is shared by another process, the VFIOGroup may not
have its container and address space in QEMU.
Besides, add a reference counter to better support getting

When multi-queue is enabled for virtio-net, each virtio
queue pair will have a vhost_dev, and the only thing they
share currently is the chardev. This patch introduces a
vhost-user state structure which will be shared by all
virtio queue pairs of the same virtio device.

vfio (hw/vfio in QEMU). If QEMU needs to trap all the
map/unmap events, the data path performance couldn't be
high. If we want to thoroughly fix this issue especially
for vfio (hw/vfio in QEMU), we need to have the offload
path Jason mentioned in QEMU. And I think accelerators
