I don't know why you want to do this tricky way. you can always register the interrupt handler, if pre-timeout is 0, system will just trigger WS1 right after WS0

But that only works if the pre-timeout and timeout can be programmed to separate values. And as Guenter says, the SBSA may not guarantee that.

In my driver patch, the first stage, I am using WCV, for the second stage I am using WOR, that have been tested on real hardware.

would you please read the pseudocode in Page 23 of SBSA 2.3
