To help in vhost analyzing, the following series adding basic tracepoints to vhost. Operations of both virtqueues and vhost works were traced in current implementation, net code were untouched. A top-like satistics displaying script were introduced to help the troubleshooting. TODO: - net specific tracepoints? --- Jason Wang (2): vhost: basic tracepoints tools: virtio: add a

Recent debugging on vhost net zerocopy shows the need of tracepoints. So to help in vhost{net} debugging and performance analyzing, the following series adding basic tracepoints to vhost. Operations of both vhost and vhost_net were traced in current implementation. A top-like satistics displaying script were introduced to help the troubleshooting: vhost statistics vhost_virtio_update_used_idx
