I have a few questions about SGI:
1. Does Xilinx-Linux use Zynq's SGI?
2. If yes to 1, is there a way to register a callback function to execute when an SGI occurs? and how to trigger a SGI interrupt?
3. If no to 1, how do I register an ISR to handle SGI interrupt(s)? and how to trigger a SGI interrupt (other than using devmem to poke SGI register)?
4. Do you have sample code?
