[...] btw., MSI is not really needed to avoid the sharing of irqs: x86 has 224 IRQ vectors which is abundant for all but the largest boxes. Even the smallest laptop tends to have an IO-APIC with at least 24 pins - which is enough to never have to share irqs. How system designers can still end up with mapping so many devices to the same pin is really their fault. so MSI's only true accomplishment AFAICS is that it now says on the hardware level that "you must not share IRQs".
