Hello,
there is now an implementation of the device for qemu internally under
review.
The paperwork with the company lawyer to publish source code has also
been done.
At the same time we changed the driver and the specification draft also,
especially the bus off indication is now done by a config space bit
instead of having a dedicated indication queue. Minor updates to some
other structures. This means what we have will match an updated driver
and specification version not yet sent out. Also to be done so that
people can play around.
So an open source qemu device is in the work and we are close to publish
this in our public github repository but until now nothing has been
pushed yet to github.
Regards
Harald

we had here at OpenSynergy an internal discussion about an open source

The outcome of this is now that an open source virtio-can device is to be
developed.
It has not yet been decided whether the open source device implementation
will be done using qemu or kvmtool (or something else?). Negative or
positive feedback for or against one of those is likely to influence the
decision what will be used as basis for the development. Using kvmtool may
be easier to do for me (to be investigated in detail) but on the other hand
we have some people around in the team who have the knowledge to support
with qemu.
It there some code available yet? We as Pengutronix will be on our
yearly techweek soon and I want to look into the VirtIO CAN stuff.
regards,
Marc
