[RFC PATCH 00/24] Control VQ support in vDPA
Hi All:
This series tries to add the support for control virtqueue in vDPA.
Control virtqueue is used by networking device for accepting various
commands from the driver. It's a must to support multiqueue and other
configurations.
When used by vhost-vDPA bus driver for VM, the control virtqueue
should be shadowed via userspace VMM (Qemu) instead of being assigned
directly to Guest. This is

[RFC 00/12] Audio DSP VirtIO and vhost drivers
This patch set is a follow up to "Add a vhost RPMsg API" [1], it is
marked as an RFC because firstly it depends on the RPMsg API series
and secondly it is currently being reviewed on ALSA and SOF mailing
lists, but any early comments from virtualisation developers would be
highly appreciated too!
Thanks
