WebWhile IRQ 0 is actually the timer (in hardware) it has a special meaning for setting a serial port with setserial. It tells the driver that there is no interrupt for the port and the driver then will use polling methods. Such polling puts more load on the CPU but can be tried if there is an interrupt conflict or mis-set interrupt.

WebThe approach here is to use PDC interrupt at all times (while keeping the GPIO irq disabled). The PDC interrupt handler invokes the action handler of the GPIO IRQ instead. This allows us to avoid interrupt hand-offs while entering idle states and keeps things very simple. The wake_irq_gpio_handler() is the crux of this new revision.

WebThis allows the HW to raise IRQs, and SW to process them, after shutdown. Fix this by masking the IRQ when it's shut down. This is usually taken care of by the irqchip core, but since this driver has a custom irq_shutdown implementation, it must do this explicitly itself. WebIf the interrupt chip does not implement the irq_disable callback, a driver can disable the lazy approach for a particular irq line by calling ‘irq_set_status_flags(irq, …
