Guys, I notice many people happened same issue to use the interrupt in powerpc with DTS. Could somebody write one documentation for interrupt system on powerpc arch, - how to remap irq - what is the virq? h/w irq. - show the mapping virt->h/w.. etc.. I think if have this docs, it will be helpful. Thanks, Dave
