I want to implement a print function in HYP mode to let the VMM to print some
information.
Now I know there are only some asm code in HYP mode. So if I want to move all
print funciton code into HYP mode may be complex.
Others advise me that I can create an upcall mechanism to call print function
in kernel. But I have no idea.
May anybody give me some advises about the upcall mechanism? Or if KVM has this
kind of mechanism already?
Thank you very much.
Harry.
