What: /config/stp-policy/<device>:p_sys-t.<policy>/<node>/uuid

KernelVersion: 4.19

Description:
|
||
|
|
UUID source identifier string, RW.
|
||
|
|
Default value is randomly generated at the mkdir <node> time.
|
||
|
|
Data coming from trace sources that use this <node> 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.

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.

|

|
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".

|
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.
