Hi,
Now that virtio-rpmsg endianness fixes have been merged we can proceed with the next step.
Which tree is this for?
The essential part of this series is for drivers/vhost, so, I presume that should be the target tree as well. There is however a small part for the drivers/rpmsg, should I split this series in two or shall we first review is as a whole to make its goals clearer?
I suggest to keep it whole for now.
Ok can I get some acks please?
Yes, as soon as I have the opportunity to review the work. There is a lot of volume on the linux-remoteproc mailing list lately and patchsets are reviewed in the order they have been received.
Also, I put this in my linux-next branch on
https://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git
there were some conflicts - could you pls test and report it's ok?
Thanks Guennadi
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
