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 1 =================== I've studied the structure of a freebsd PCI NIC driver and implemented the basic device methods for ptnet (device probe attach, detach), including device capabilities discovery, ethernet interface initialization and MSI-X interrupt service routine setup.
