IPI Interrupt forwarding

Post by kemosparc »

Hi,

I am trying to implement IPI interrupt forwarding.

I would like to understand how this works, in specific:
What should be stored in the vector field of the ICR bit 0-7
What is the delivery modre that needs to be used, e.g NMI,SMI ??
How is this interrupt is received by the AP?
How is this interrupt fires the execution of the interrupt handler on the AP?

I have read the intel manuals, and searched documentation on OSDev and on google and I could not find anything useful.

For example I could not know what SMI stands for !!!

If anyone can help me with pointing

Thanks
karim.
