But again, we didn't even request > the irq, why would we disable it? The driver does not request IRQs for dummy ports, but it still requests MSIs for them. The MSI framework initializes the resources for all MSIs (IRQ #s, CPU interrupt vectors). Hence, although we do not request a IRQ #, it still exists - just with no handler associated with the driver. IOW - with a default handler, which would probably complain loudly once an interrupt from a dummy port comes (I suppose David could check it). So if we just disable dummy port's IRQ #s we should never hear from them. > Thanks. > > -- > tejun -- Regards, Alexander Gordeev agordeev@xxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
