> 
> This patcheset add a device to allow guest machines with assigned
> hardware devices to send encoded video and other informations that
> will be handled as a normal display by Spice.
> 
> New GPU devices are capable to capture and encode video in an
> efficient way. As the GPU in this case is assigned to the guest
> and not the host is easier if the guest do the hard job.
> 
> This patchset add a new "com.redhat.stream.0" device visible to
> the guests. This device will be used by the guest to send streaming
> data. The host will forward the data to the client.
> 
> To do so a new StreamChannel class, implementing the protocol
> DisplayChannel is implemented.

> Frediano Ziglio (19):
>   char-device: Allows to handle port events from any char device
>   stream-device: Add device to handle streaming
>   stream-device: Start parsing new protocol from guest
>   stream-channel: Write a really base channel to implement the streaming
>   stream-channel: Start implementing DisplayChannel properly
>   stream-device: Create channel for stream device
>   stream-channel: Implements initialization
>   stream-device: Handle streaming data from device to channel
>   stream-channel: Allows not fixed size
>   stream-channel: Allows to register callback to get new stream request
>   stream-channel: Support client connection/disconnection
>   stream-channel: Do not show an empty blank screen on start
>   char-device: Do not stop and clear interface on reset
>   stream-device: Start supporting resetting device when close/open on
>     guest
>   stream-device: Limit sending queue from guest to server
>   stream-channel: Activate streaming report from client
>   WIP cursor-channel: Allow to not handle a QXL device
>   WIP stream-device: handle cursor from device
>   WIP: Try to reduce delay
