eBPF is a revolutionary technology that can run sandboxed programs in the Linux kernel without changing kernel source code or loading a kernel module. Receive side scaling (RSS) is the mechanism of packet steering for multi-queue NICs optimizing multiple CPU utilization. The first usage of eBPF in QEMU is the optimization of the RSS packet steering in virtio-net. During this session, Yan will provide the motives for the RSS optimization using eBPF, review the technical solution, describe integration with libvirt, and discuss future development and additional usages of eBPF in QEMU.
