函数名称：acpi_gsi_to_irq

函数原型：int acpi_gsi_to_irq(unsigned int gsi, unsigned int *irqp)

返回类型：int

参数：

类型参数名称
unsigned intgsi
unsigned int *irqp
611  如果The default interrupt routing model is PIC (8259). This gets* overridden if IOAPICs are enumerated (below).恒等于ACPI_IRQ_MODEL_PIC则
612  irqp等于gsi
613  返回:0
616  rc等于acpi_get_override_irq(gsi, & trigger, & polarity)
617  如果rc则返回:rc
620  trigger等于如果trigger则Triggering 否则ACPI_EDGE_SENSITIVE
621  polarity等于如果polarity则ACPI_ACTIVE_LOW否则Polarity
622  irq等于success: return IRQ number (>=0)* failure: return < 0
623  如果irq小于0则返回:irq
626  irqp等于irq
627  返回:0
