WIP Presentations
Edgar’s QEMU work:
Meeting notes Aug 1
Meeting notes Aug 15
Alex: Asked Edgar if he would rebase / squash his QEMU virtio-msg work for potential up streaming
Not really ready for that
Edgar: Asked Alex about EL3 Split accelerator (EL1 and EL0 in KVM, EL3 EL2 in TCG)
Alex: some discusion on that work is happening on that but it is still private and uncommitted
Actions:
AI: Lei to work with Julianus to make 1st public home page for virtio-msg vsock ff-a tee project
AI: Bill Edgar Stefano to define HVAC Demo1 and HVAC Demo2
AI: Bill Alex Lei Viresh to work out first viable kernel milestone
AI: Bill and Edgar to talk about mailbox format
Meeting notes Aug 29
Action Update
1st kernel intersection
Viresh Kumar has a prototype of kernel level virtio-msg talking via io-req (via Xen) to a vhost-user based device model (in rust). This was a reuse of work that already existed and Viresh was already familiar with. This is a stepping stone to allow Viresh to focus on the common part of virtio-msg in the kernel. This work implements the same virtio-msg to virtio-msg-bus interface abstraction that Edgar did in the QEMU work. Aligiing this interface with the spec or vise-versa will be worked out later. (Viresh has 2 weeks of vacation and 1 week of business travel in September so we are getting this hand off as soon as possible.)
Lei Zhou is checking out the FF-A direct message interface in prep for the mid September intersection with Trusty TEE than will implement device side of VSOCK. Virtio-msg-bus-ffa will proceed from that point.
Bill Mills will look at kernel side of virtio-msg-bus-amp (based on Viresh’s work) with target by end of September for initial inter-working with Edgar’s QEMU branch
AMP Mailbox format: Bill Mills and Edgar Iglesias had discussion on AMP mailbox format. Both have additional prototype work to do before any decision is made.
Lei Zhou has done work with Google on making the Trusty-virtio project portal public
No update/change on HVAC Demo1 and Demo2
