函数名称：irq_domain_associate

函数原型：int irq_domain_associate(struct irq_domain *domain, unsigned int virq, irq_hw_number_t hwirq)

返回类型：int

参数：

类型	参数	名称
struct irq_domain *	domain
unsigned int	virq
irq_hw_number_t	hwirq

536

irq_data等于irq_get_irq_data(virq)

539

如果WARN(hwirq >= reverse map data. The linear map gets appended to the irq_domain , "error: hwirq 0x%x is too large for %s\n", (int)hwirq, 硬件中断对象名)则返回:负EINVAL

542

如果WARN(!irq_data, "error: virq%i is not allocated", virq)则返回:负EINVAL

544

如果WARN(硬件中断对象, "error: virq%i is already associated", virq)则返回:负EINVAL

547

mutex_lock( & irq_domain_mutex)

548

硬件中断号等于hwirq

549

硬件中断对象等于domain

550

如果map则

551

ret等于map(domain, virq, hwirq)

552

如果ret不等于0则

558

如果ret不等于负EPERM则

559

打印信息("%s didn't like hwirq-0x%lx to VIRQ%i mapping (rc=%d)\n", 硬件中断对象名, hwirq, virq, ret)

562

硬件中断对象 = NULL

563

硬件中断号等于0

564

mutex_unlock - release the mutex*@lock: the mutex to be released* Unlock a mutex that has been locked by this task previously.* This function must not be used in interrupt context. Unlocking* of a not locked mutex is not allowed.

565

返回:ret

569

如果非硬件中断对象名且中断控制器信息则硬件中断对象名等于中断名

573

mapcount自加

574

irq_domain_set_mapping(domain, hwirq, irq_data)

575

577

irq_clear_status_flags(virq, IRQ_NOREQUEST)

579

返回:0
