4 Trace agent is a user tool for sending trace data of a guest to a Host in low
41 1) Make FIFO in a host
45 	# mkfifo /tmp/virtio-trace/trace-path-cpu{0,1,2,...,X}.{in,out}
46 	# mkfifo /tmp/virtio-trace/agent-ctl-path.{in,out}
49 	trace-path-cpu{0,1,2}.{in.out}
51 	agent-ctl-path.{in,out}.
53 2) Set up of virtio-serial pipe in a host
87  You can find some chardev in /dev/virtio-ports/ in the guest.
93 0) Build trace agent in a guest
96 1) Enable ftrace in the guest
100 2) Run trace agent in the guest
103 read/write threads in the agent wait for start order from host. If you add -o
104 option, trace data are output via stdout in the guest.
106 3) Open FIFO in a host
108 If a host does not open these, trace data get stuck in buffers of virtio. Then,
109 the guest will stop by specification of chardev in QEMU. This blocking mode may
110 be solved in the future.
