Thanks Liam for tagging the release. We are still working on late SDMA bugs hope we can catch this release. Other than that we will update for furter v1.5 stable releases (e.g v1.5.1, v1.5.2 etc). When is your plan to do the official release? Maybe at least wait till Monday. Also, I wonder if it makes sense to create our on v1.5-imx branch. Daniel.

Ok, I'll route them via Pierre then, because they include a new SOF IPC, which probably requires an ABI version update, even though it will never be sent to the DSP. Thanks Guennadi

Sorry, we were thinking about the best way to reply. I think Liam will provide more procise information. The API we are using is the same as what is already used by SOF to communicate with the DSP firmware. With VirtIO we re-use the same IPC messages as those, used with the DSP, they are just transmitted over Virtual Queues. Additionally to existing IPC messages the SOF VirtIO implementation defines 3 more message types for topology loading and DSP power management. IPC message types are defined in include/sound/sof/header.h, IPC overview is available in https://thesofproject.github.io/latest/developer_guides/linux_driver/archit… but I'm not aware of a formal SOF IPC protocol documentation. Thanks Guennadi

[Sound-open-firmware] [PATCH v2 00/12] [RESEND] ASoC: SOF DSP virtualisation
by Guennadi Liakhovetski 03 Apr '20

03 Apr '20

This patch series extends the SOF driver to add support for DSP virtualisation to ASoC. It is built on top of VirtIO, contains a guest driver and a vhost in-kernel guest driver. This version supports a single playback and a single capture interface on the guest. The specific guest audio topology is supplied by the host from a file, specified on the QEMU command line. This solution is designed to use advanced DSP functionality, available on the host. In case no DSP is available on the host, a fall-back should be provided in the future to the pure audio virtualisation standard, currently developed by OASIS. Extensive documentation is available at [1]. I'd like to have at least a tentative approval on this series to send vhost patches 3 and 9 to virtualisation lists / maintainers for review and eventual merging. v2: one patch merged, one patch resubmitted separately, otherwise no changes.
