函数名称:注册中断线程
函数原型:int request_threaded_irq(unsigned int irq, irq_handler_t handler, irq_handler_t thread_fn, unsigned long irqflags, const char *devname, void *dev_id)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
unsigned int | irq | |
irq_handler_t | handler | |
irq_handler_t | thread_fn | |
unsigned long | irqflags | |
const char * | devname | |
void * | dev_id |
1968 | 如果irq恒等于If a (PCI) device interrupt is not connected we set dev->irq to* IRQ_NOTCONNECTED则返回:负ENOTCONN |
1989 | 如果非设置请求参数或WARN_ON(irq_settings_is_per_cpu_devid(desc))则返回:负EINVAL |
1993 | 如果非handler则 |
1996 | handler等于线程中断的默认主中断处理程序 |
2009 | retval等于q_chip_pm_get - Enable power for an IRQ chip*@data: Pointer to interrupt specific data* Enable the power to the IRQ chip referenced by the interrupt data* structure. |
2010 | 如果retval小于0则 |
2017 | 如果retval则 |
2042 | 返回:retval |
