  1. What: /config/stp-policy/<device>:p_sys-t.<policy>/<node>/uuid
  2. Date: June 2018
  3. KernelVersion: 4.19
  4. Description:
  5. UUID source identifier string, RW.
  6. Default value is randomly generated at the mkdir <node> time.
  7. Data coming from trace sources that use this <node> will be
  8. tagged with this UUID in the MIPI SyS-T packet stream, to
  9. allow the decoder to discern between different sources
  10. within the same master/channel range, and identify the
  11. higher level decoders that may be needed for each source.
  12. What: /config/stp-policy/<device>:p_sys-t.<policy>/<node>/do_len
  13. Date: June 2018
  14. KernelVersion: 4.19
  15. Description:
  16. Include payload length in the MIPI SyS-T header, boolean.
  17. If enabled, the SyS-T protocol encoder will include payload
  18. length in each packet's metadata. This is normally redundant
  19. if the underlying transport protocol supports marking message
  20. boundaries (which STP does), so this is off by default.
  21. What: /config/stp-policy/<device>:p_sys-t.<policy>/<node>/ts_interval
  22. Date: June 2018
  23. KernelVersion: 4.19
  24. Description:
  25. Time interval in milliseconds. Include a timestamp in the
  26. MIPI SyS-T packet metadata, if this many milliseconds have
  27. passed since the previous packet from this source. Zero is
  28. the default and stands for "never send the timestamp".
  29. What: /config/stp-policy/<device>:p_sys-t.<policy>/<node>/clocksync_interval
  30. Date: June 2018
  31. KernelVersion: 4.19
  32. Description:
  33. Time interval in milliseconds. Send a CLOCKSYNC packet if
  34. this many milliseconds have passed since the previous
  35. CLOCKSYNC packet from this source. Zero is the default and
  36. stands for "never send the CLOCKSYNC". It makes sense to
  37. use this option with sources that generate constant and/or
  38. periodic data, like stm_heartbeat.
