What: /config/stp-policy/:p_sys-t.//uuid Date: June 2018 KernelVersion: 4.19 Description: UUID source identifier string, RW. Default value is randomly generated at the mkdir time. Data coming from trace sources that use this will be tagged with this UUID in the MIPI SyS-T packet stream, to allow the decoder to discern between different sources within the same master/channel range, and identify the higher level decoders that may be needed for each source. What: /config/stp-policy/:p_sys-t.//do_len Date: June 2018 KernelVersion: 4.19 Description: Include payload length in the MIPI SyS-T header, boolean. If enabled, the SyS-T protocol encoder will include payload length in each packet's metadata. This is normally redundant if the underlying transport protocol supports marking message boundaries (which STP does), so this is off by default. What: /config/stp-policy/:p_sys-t.//ts_interval Date: June 2018 KernelVersion: 4.19 Description: Time interval in milliseconds. Include a timestamp in the MIPI SyS-T packet metadata, if this many milliseconds have passed since the previous packet from this source. Zero is the default and stands for "never send the timestamp". What: /config/stp-policy/:p_sys-t.//clocksync_interval Date: June 2018 KernelVersion: 4.19 Description: Time interval in milliseconds. Send a CLOCKSYNC packet if this many milliseconds have passed since the previous CLOCKSYNC packet from this source. Zero is the default and stands for "never send the CLOCKSYNC". It makes sense to use this option with sources that generate constant and/or periodic data, like stm_heartbeat.
