    I can't think of a reason why the driver prevents people from setting any
    custom bits in their platform device, but I can think of some reasons for
    allowing custom flags. Like setting the IRQF_TRIGGER_... bits.

  • c767db0ab   UIO: generic irq handling for some uio platform devices ... Browse Code »

    This is V3 of uio_pdrv_genirq.c, a platform driver for UIO with
    generic IRQ handling code. This driver is very similar to the regular
    UIO platform driver, but is only suitable for devices that are
    connected to the interrupt controller using unique interrupt lines.

    The uio_pdrv_genirq driver includes generic interrupt handling code
    which disables the serviced interrupt in the interrupt controller
    and makes the user space driver responsible for acknowledging the
    interrupt in the device and reenabling the interrupt in the interrupt
    controller.

    Shared interrupts are not supported since the in-kernel interrupt
    handler will disable the interrupt line in the interrupt controller,
    and in a shared interrupt configuration this will stop other devices
    from delivering interrupts.
