Does this message (specifically the WCS / WCV values) have any
useful meaning for the user ?
I think so, according to SBSA spec:
If WS0 is asserted and a timeout refresh occurs then the following must occur:
If the system is compliant to SBSA level 2 or higher the compare
value must retain its current value. This means that the compare value
records the time that WS1 is asserted.
So, I think WCV can log the time when system reset by WDT, that may
help user figure out the problem. but WCS can be delete I think.
How would that help ? It is just a number with no reference to anything.
Thanks,
Guenter
