[Xen-devel] Interrupt entry points in xen-3.x

["Furquan Shaikh" <furquan.m.shaikh@xxxxxxxxx>]

I was studying interrupt handling in xen-3.x. I came across "create_bounce_frame" in xen-3.3.0/xen/arch/x86/x86_32/entry.S
I am having some problem understanding the flow of code. Can somebody please give me a step-by-step overview of the flow of interrupt handling right after an interrupt occurs and h/w transfers control to xen. Where is the control passed in xen? (exact entry point)


please help me.
