I have made a start by quickly compiling teh following table from vxWorks
console output and what I found in the sources. It might be incomplete
and/or erroneous.
A couple of small additions:
------------- ------ ------- ----------------------------
ts_Casync 109 90=High drvTS (apsEvent module)
in drvTS (which will hopefully soon be history) this task communicates
either with a
NTP time server or a "timing master" IOC to synchronize the local time
to one of these
time sources. This is executed typically rather seldom (like once in 10
sec), defined by
the TS sync rate parameter in TSConfigure.
TSwdIncTime 109 90=High drvTS (apsEvent module)
This is a "Watchdog task", and the essential part of the code runs at
interrupt level.
This routine increments the IOC local time every system clock tick (60
Hz, unless set
otherwise.)
In the new code that also Ralph Lange mentioned a couple of days ago, we
have got
rid of this stuff (and I am very happy about that.)
