That means we mark the interrupt disabled, but\nleave the hardware unmasked. That\u0027s an optimization because we avoid\nthe hardware access for the common case where no interrupt happens\nafter we marked it disabled. If an interrupt happens, then the\ninterrupt flow handler masks the line at the hardware level and marks\nit pending.\n\nSuspend makes use of this delayed disable as it \"disables\" all\ninterrupts when preparing the suspend transition. Right before the\nsystem goes into hardware suspend state it checks whether one of the\ninterrupts which is marked as a wakeup interrupt came in after\ndisabling it.\n\nMost interrupt chips have a separate register which selects the\ninterrupts which can wake up the system from suspend, so we don\u0027t have\nto mask any on the non wakeup interrupts.\n\nBut now we have to deal with brilliant designed hardware which lacks\nsuch a wakeup configuration facility. For such hardware it\u0027s necessary\nto mask all non wakeup interrupts before going into suspend in order\nto avoid the wakeup from random interrupts.\n\nRather than working around this in the affected interrupt chip\nimplementations we can solve this elegant in the core code itself.\n\nAdd a flag IRQCHIP_MASK_ON_SUSPEND which can be set by the irq chip\nimplementation to indicate, that the interrupts which are not selected\nas wakeup sources must be masked in the suspend path.
