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 3 =================== I've completed the implementation of the netmap support for the ptnet driver, done testing and bug-fixing. The current driver version integrates with netmap to support applications running in netmap mode over the ptnet device. The performance is good as expected: 25-30 Mpps throughput at minimum packet rate between a FreeBSD guest and the host, over a VALE switch.
