Hi,
Next update:
v7:
- remove documentation update to be send separately
- address comments from Mathieu Poirier (thanks)
v6:
- rename include/linux/virtio_rpmsg.h -> include/linux/rpmsg/virtio.h
v5:
- don't hard-code message layout
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
