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 5 =================== In this week I kept going on with the driver implementations, adding taskqueues to manage deferred RX/TX work, fixing several synchronization problems and expanding the support for ioctl(). Some more bug-fixing work is needed to get the driver working, and I plan to do that in week 6, together with performance tests.
