Adding the dependencies to VHOST and VHOST_RING themselves is indeed not sufficient. But IMHO you should still add VHOST_DPN dependencies t these two symbols, so any driver selecting them without fulfilling the VHOST_DPN dependency will trigger a Kconfig warning.

But no, this RPMsg driver doesn't depend on vsock, on the contrary, it takes a (albeit tiny) piece of functionality from vsock and makes it...

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,
