tools: virtio: introduce vhost_net_test

2024-03-05T10:38:14Z

introduce vhost_net_test for both vhost_net tx and rx basing on virtio_test to test vhost_net changing in the kernel. Steps for vhost_net tx testing: 1. Prepare a out buf. 2. Kick the vhost_net to do tx processing. 3. Do the receiving in the tun side. 4. verify the data received by tun is correct. Steps for vhost_net rx testing: 1. Prepare a in buf. 2. Do the sending in the tun side. 3. Kick the vhost_net to do rx processing. 4. verify the data received by vhost_net is correct. Signed-off-by: Yunsheng Lin Acked-by: Michael S.

tools/virtio: use canonical ftrace path

2023-06-09T16:08:08Z

The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing A few spots in tools/virtio still refer to this older debugfs path, so let's update them to avoid confusion.
