It is built on top of VirtIO, contains a guest driver and a vhost in-kernel guest driver. This version supports a single playback and a single capture interface on the guest. The specific guest audio topology is supplied by the host from a file, specified on the QEMU command line. This solution is designed to use advanced DSP functionality, available on the host. In case no DSP is available on the host, a fall-back should be provided in the future to the pure audio virtualisation standard, currently developed by OASIS. Extensive documentation is available at [1]. Signed-off-by: Guennadi Liakhovetski v2: one patch merged, one patch resubmitted separately, otherwise no changes.
