Multi-tasking related...

Post by Neo »

Hi,
  I was wondering how (or if it is possible) to find out from within an interrupt handler to get the last IP (instruction pointer) before the interrupt was called.  I'm hoping to implement some sort of pre-emptive multitasking using the system timer.
Thanks in advance!

cs:eip and eflags get saved on the interrupt handler's stack just as in real mode. not sure about the order, anyway. and you can get it to work, i did it exactly the same way :)
