[Xen-devel] interrupt handling in xen

[Diwaker Gupta <diwaker.lists@xxxxxxxxx>]

I'm trying to understand interrupt handling in Xen (as described in
the "Restructuring I/O" techreport). But I'm having a hard time
finding all the bits and pieces in the code.

For instance, the text says "a device's interrupt line triggers
execution of a stub routing within  Xen rather than causing immediate
entry into the domain that is managing that device". Can someone point
me to the code where this takes place?

TIA
