  • dd1dafcdf   irqchip/eznps: Drop pointless static qualifier in nps400_of_init() ... Browse Code »

    There is no need to have the 'struct irq_domain *nps400_root_domain'
    variable static since new value is always assigned before use.

  • c0ca8df71   irqchip/eznps: Acknowledge NPS_IPI before calling the handler ... Browse Code »

    IPI_IRQ (also TIMER0_IRQ) should be acked before the action->handler is called
    in handle_percpu_devid_irq.

    The IPI irq is edge sensitive and we might miss an IPI interrupt if it is
    triggered again while the handler runs.

    Adding EZchip NPS400 support.
    Internal interrupts are handled by Multi Thread Manager (MTM)
    Once interrupt is serviced MTM is acked for deactivating the interrupt.
    External interrupts are handled by MTM as well as at Global Interrupt
    Controller (GIC) e.g. serial and network devices.
