Hello,
Would there be virtio-audio spec in future for clean audio interface?
Projectacrn.github.io provides one virtio-audio interface for automotive sytems.

Veera

That's interesting to know. It would probably be up to projectacrn to
submit virtio-audio to the committee, or at least reserve the device
number. Do you have a contact at projectacrn that can help with this?
Thanks,
Paolo

Hi,
No I don't have a contact with Project ACRN.
ACRN is a Linux Foundation Project. Initially it was by Intel.
It is a hypervisor for embedded devices.
Website is https://projectacrn.org/.
Their supported virtio-audio details:
Vendor ID: 0x8086
Device ID: 0x8603
Subvendor ID: 0x8086
Subdevice ID: 0xFFFD
Another implementation from another developer from Intel.
Website: https://patchwork.freedesktop.org/patch/174013/
Author: Luo Xionghu <xionghu.luo@intel.com>
Comments by Author: this patch only add audio device pci registration.
need add audio part to call audio Backend driver later.
Regards,
Veera

Thanks, that's useful. Xionghu, is there a public spec for
virtio-audio, and/or does Intel intend to contribute it to the virtio
specification?
Unfortunately device id 21 is already taken. I'll send a patch to the
specification that reserves id 25 for virtio-audio.
Thanks,
Paolo

Matti, IIRC you talked about virtio-audio as well at KVM Forum
Virtio BoF?

CC acrn community.
There are quite some new virtio devices (audio, gpio, i2c, etc) included in
acrn project, as required in automotive/embedded usages. I know they
have plan to upstream those bits, and now might be a good time to talk
about the plan. :-)
Thanks
Kevin
