[RFC,00/12] Audio DSP VirtIO and vhost drivers

Message

Guennadi Liakhovetski May 29, 2020, 7:37 a.m. UTC

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
Guennadi
