函数名称:q_create_strict_mappings() - Map a range of hw irqs to fixed linux irqs*@domain: domain owning the interrupt range*@irq_base: beginning of linux IRQ range*@hwirq_base: beginning of hardware IRQ range*@count: Number of interrupts to map* This routine is

函数原型:int irq_create_strict_mappings(struct irq_domain *domain, unsigned int irq_base, irq_hw_number_t hwirq_base, int count)

返回类型:int

参数:

类型参数名称
struct irq_domain *domain
unsigned intirq_base
irq_hw_number_thwirq_base
intcount
719  of_node等于irq_domain_get_of_node(domain)
720  ret等于use macros to avoid needing export.h for THIS_MODULE (irq_base, irq_base, count, of_node_to_nid(of_node))
722  如果此条件成立可能性小(为编译器优化)(ret < 0)则返回:ret
725  irq_domain_associate_many(domain, irq_base, hwirq_base, count)
726  返回:0
