| H A D | README | 1 Trace Agent for virtio-trace
4 Trace agent is a user tool for sending trace data of a guest to a Host in low
8 - write trace data to stdout by using -o option
11 The trace agent operates as follows:
16 4) After the controller of the trace agent receives a start order from a host,
18 5) The read/write threads start to read trace data from ring-buffers and
21 stop to read trace data.
28 Makefile: Makefile of trace agent for virtio-trace
29 trace-agent.c: includes main function, sets up for operating trace agent
30 trace-agent.h: includes all structures and some macros
