REQUEST_PERCPU_IRQ(9)               Public Functions Provided               REQUEST_PERCPU_IRQ(9)



NAME
       request_percpu_irq - allocate a percpu interrupt line

SYNOPSIS
       int request_percpu_irq(unsigned int irq, irq_handler_t handler, const char * devname,
                              void __percpu * dev_id);

ARGUMENTS
       irq
           Interrupt line to allocate

       handler
           Function to be called when the IRQ occurs.

       devname
           An ascii name for the claiming device

       dev_id
           A percpu cookie passed back to the handler function

DESCRIPTION
       This call allocates interrupt resources and enables the interrupt on the local CPU. If the
       interrupt is supposed to be enabled on other CPUs, it has to be done on each CPU using
       enable_percpu_irq.

       Dev_id must be globally unique. It is a per-cpu variable, and the handler gets called with
       the interrupted CPU's instance of that variable.
