Hi,
I am building some device models around the KVM and am intersted in injecting IRQs.
The current LibKVM.h provides following function
int kvm_inject_irq ( kvm_context_t<file:///C:/Documents%20and%20Settings/asaksena/Desktop/march_onwards/kvmsocket/doc/htmlkvm/structkvm__context.html> kvm,
int vcpu,
unsigned irq
)
Simulate an external vectored interrupt.
This allows you to simulate an external vectored interrupt.
Parameters:
kvm Pointer to the current kvm_context<file:///C:/Documents%20and%20Settings/asaksena/Desktop/march_onwards/kvmsocket/doc/htmlkvm/structkvm__context.html>
vcpu Which virtual CPU should get dumped
irq Vector number
Returns:
0 on success
My question is if I am say Injecting IRQ on pin 0 on PIC how do I get croosponding vector? I am using KVM's interrupt controllers.
I also see another function
int kvm_set_irq_level ( kvm_context_t<file:///C:/Documents%20and%20Settings/asaksena/Desktop/march_onwards/kvmsocket/doc/htmlkvm/structkvm__context.html> kvm, int irq, int level )
Can this be used safely to inject IRQ- I am gusseing irq refers to the pin and Level the value of that pin. How do I tell with this function which CPU I want to inject interrupt?
