Hello Project summary ================= ptnet is a new multi-queue paravirtualized device that builds on ptnetmap to allow VMs to exchange TCP traffic at 20 Gbps, while still offering the same ptnetmap performance (10-100 Mpps) to native netmap applications. The purpose of this SOC project is to write a ptnet driver for FreeBSD and a corresponding device model for the bhyve hypervisor. Status update for week 10 =================== In week 10 I updated and fixed the netmap support to bhyve, including the introduction of an interface between virtio-net and the backends (TAP, netmap, NULL). I recompiled the freebsd kernel and modules with extended libvmm (which support VM exits to be caught from inside the kernel). Finally, I sketched a first skeleton of the ptnet device model emulation. I've not managed to upload all the code yet, will work on it next week.
