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 5 overhead. Trace agent has the following functions: 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 [all …]
