New attendees in the invite list
Sangshetty Patil (AMD San Jose, monitoring)
Sean Keys (Android Auto all things Virtulization)
Bill has started a Demo and CI project for all the individual demos
Viresh’s kernel demo is there and works with 100% automation
The project builds everything and can run it
Bill is in the process of adding Edgar’s demos from here
Happy to rename the project if we want to broaden the scope to all of virtio-msg but need owners for the write up of each demo to be added. (Like Viresh and Edgar did).
Plan to enable this as CI
Bertrand published his work in Xen for FFA indirect message support
Needs kernel work to match but right now no one is available from Linaro
Arm is working on kernel side FFA v1.2 target kernel v6.12
Working to bring Xen up to FFA v1.2
We have created the mailing list virtio-msg@lists.linaro.org
Bill added everyone in the meeting invite but not all may have been successful.
email me directly bill.mills@linaro.org if you are having issues
Updates from Edgar
Xen mediated virtio-proxy?
proxy is in xen hypervisor (not public (yet))
qemu is doing foreign memory maps and xen events for notification
Trying to do something that works with current kernels
What is this message-queue thing? It is Gaunha hypervisor specific message passing
Updates from Lei?
Getting ready to take Google’s Trusty Virtio-msg VSOCK drop
Using Viresh’s base
Armelle’s updates
Trusty drop
will be QEMU based drop
Will be switching to virtio-msg / FFA
The Rust dependecies were a struggle to integrate into TEE environment
microDroid VM Update
Linux frontend and backend w/ virtio-msg-ffa VM to VM
Backend is microDroid w/ RustVMM devices
CrossVM
Google’s RustVMM based VMM
End goal is to have VM to VM
What about header files for the messages
Desire to dual license the Linux header file at least to start
Edgar
Spec updates: disable queues, and others.
Need to be able to shutdown and bring back up
Cleanup & restart after abortive shutdown of either side
Graceful shutdown initiated from the device (like eject button on CD)
Should we be giving a heads-up to the upstream virtio spec owners?
Alex: Viresh has sent a clean-up set of patches defining transport level better
This is in prep to add a new transport (virtio-msg)
