A " fast interrupt return " option is available for interrupts. 中断有一个“快速中断返回”选项。
The data structure and operation process related to the fault recovery implemented by technique of exception interrupt return is discussed in detail. The special case of fault recovery of the power - on upgrade reconfiguration is analyzed. 文中详细讨论了利用异常中断返回技术实现系统故障恢复所涉及的数据结构及具体运行过程,并对上电升级重构这种特殊的故障恢复情况进行了分析。
Once the interrupts are generated, reset the interrupt simulation status flag and return success. 中断生成之后,就重新设置中断模拟状态标志,并返回成功。
The interrupt handler function now has a return code of type irqreturn_t. 现在的中断处理函数的返回代码是一个irqreturnt类型。
If the interrupt simulation status flag is set, return EBUSY. 如果设置了中断模拟状态标志,它就会返回EBUSY。
