Subject: [PATCH v2 0/5] Add a vhost RPMsg API
Date: Mon, 25 May 2020 16:44:53 +0200 [thread overview]
Message-ID: <20200525144458.8413-1-guennadi.liakhovetski@linux.intel.com> (raw)
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 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
A further patch for the ADSP vhost RPMsg driver will be sent
separately for review only since it cannot be merged without audio
patches being upstreamed first.
Thanks
Guennadi
