Benchmarks:
We have designed two device agnostic benchmark tests for measuring and comparing latency and throughput between virtio-loopback and "QEMU & vhost-user" cases.
The latency benchmark has been completed and we have already the final results by performing it on a RPI4. Lastly, this week we designed and we are at the process to finalize the implementation of throughput benchmark. Next week, out efforts will be focused to complete the throughput benchmark and start creating a presentation which includes the overall results.
GPU:
The work focused on investigating runtime errors of vhost-user-gpu & virtio-gpu device models on virtio-loopback-adapter. This includes sequences of
virtio-gpu protocol requests of the backend (contrib/vhost-user-gpu) and the actions performed by the virtio-gpu device support on virtio-loopback-adapter.
Such requests are mishandled by adapter's virtio-gpu support resulting in crash/hangup and returning invalid data to the rendering pipeline. Started an effort
to rewire the virtio-gpu model emulation on a QEMU process and let virtio-loopback-adapter handle only the transport path of 'virtqueues' using virtio-loopback.
Next steps include the analysis, resolution of the virtio-gpu device model integration and wiring on virtio-loopback-adapter.
