[Qemu-devel] [RFC 0/2] vhost-user: Specify device IOTLB support

[Maxime Coquelin]

This two-patches series aims at specifying the protocol update
required to support device IOTLB with user backends.

The protocol is very close to kernel backends, except that a new
communication channel is introduced to enable the slave to send
requests to the master.

While unix sockets are bidirectionnal, I create a dedicated channel
for slave intiated requests to simplify message handling with multi-
threaded masters and slaves.

Maxime Coquelin (2):
  spec/vhost-user: Introduce secondary channel for slave initiated
    requests
  spec/vhost-user spec: Add IOMMU support
