bind_virq_to_irq() and bind_evtchn_to_irq() bind these various virtual
interrupt sources into Linux's normal irq-handling subsystem.
A common way of setting a handler for virq, for example, is:
irq = bind_virq_to_irq(VIRQ_FOO);
request_irq(irq, ...);

Hi, all
I am reading Xen's source code. Currently it seems that I have some difficulty
in finding the interrupt handlers of the virtual machine. In
arch/xen/kernl/Evtchn.c, a fucntion
int bind_virq_to_irq (int virq)
is defined to map virtual irq to irq. However, how can I find the handlers for
these irq?
Take the network interrupts as an example, in
arch/xen/drivers/network/Network.c,
bind_virq_to_irq is called to set the interrupt handler. However, the source
code is
network_irq = bind_virq_to_irq(VIRQ_NET);
....
No specific function pointers are mentioned in this process. So, how these
interrupt
handlers are set?
Thanks a lot!
Andy
