v2: - remove "default n" from Kconfig - drop patch #6 - it depends on a different patch, that is currently an RFC - update patch #5 with a correct vhost_dev_init() prototype Linux supports RPMsg over VirtIO for "remote processor" /AMP use cases. It can however also be used for virtualisation scenarios, e.g. when using KVM to run Linux on both the host and the guests. This

Linux supports RPMsg over VirtIO for "remote processor" /AMP use cases. It can however also be used for virtualisation scenarios, e.g. when using KVM to run Linux on both the host and the guests. This patch set adds a wrapper API to facilitate writing vhost drivers for such RPMsg-based solutions. The first use case is an audio DSP virtualisation project, currently under development,
