However, it is at the very least fragile. I think we should focus on SBSA spec, but not a specific chip design, because this is SBSA watchdog, not a driver for an IP core from a specific chip vendor. this operation is mentioned in the spec, and I have tested my driver on Foundation model(from ARM) and a real hardware. > > I tend to agree that we should just forget about pretimeout and > use your original approach, where the timeout value is used > to program WOR. Everything else is really just asking for trouble. I don't mind if we give up pretimeout, The reason I use pretimeout is: this concept matches the function of two stage timeouts. but, If we give up pretimeout, could you give me a suggestion: How to config the two stage timeouts (1)from enabling watchdog to WS0 (2)the time from WS1 to WS0 If we only have one timeout parameter, How to config the two stage timeouts? Any suggestion ? If we make the first stage timeout is timeout/2, this violates the definition of timeout. I don't think users expect interrupt, panic or reboot at timeout/2.
