Hi,
Now that virtio-rpmsg endianness fixes have been merged we can proceed with the next step.
v4: - add endianness conversions to comply with the VirtIO standard
v3: - address several checkpatch warnings - address comments from Mathieu Poirier
v2: - update patch #5 with a correct vhost_dev_init() prototype - drop patch #6 - it depends on a different patch, that is currently an RFC - address comments from Pierre-Louis Bossart: * remove "default n" from Kconfig
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, ready for review and submission, available at https://github.com/thesofproject/linux/pull/1501/commits
Thanks Guennadi
