A tool to test the functionalities required by Linuxptp in a controlled manner. Rather than running the complex daemons you can use tstest to try out one functionality at a time. Great for debugging purposes.
tstest pktcan send and receive individual packets with timestamps.tstest delaycan perform basic peer delay measurement.tstest exttscan listen to EXTTS events from the kernel.tstest tccan measure TC time error, latency, and more.tstest ppscan configure PPS.
- Add BC Time Error support (either just receiver, or act as both GM and Slave).
- Add E2E delay
- Idea:
tstest checkmode that takes a config file of actions it should check (send, receive, verify values). Should be run with a looped cable, else it would require two instances (which might be an option too).
- Better handling for finding the initial max/min values. Use INT MIN/MAX?
- Change to use capture time and interval, rather than packet count
- P2P measurement
- build_msg() should take portIdentity
- Export Delay and Twoway error. Alternatively, only export packet data and calculate externally (note: internal calculation is also desired since we want to give quick output).
- BC mode
- Refactor stats.c to better map messages???
- Fix SeqID handling to have separate counters for each packet type.
Some of the code is directly taken from the Linuxptp project and the Linux kernel and simplified/modified.
