摘　　要：中断请求级IRQL是Windows操作系统内核的重要概念,WDM驱动程序的设计经常涉及到IRQL的应用。研究了Windows操作系统下WDM驱动程序中IRQL的实质,IRQL对线程调度的影响,研究了IRQL与处理器环级、线程优先级、硬件IRQ之间的区别与联系,分析了用IRQL实现自旋锁的原理。Interrupt request level is an important idea of the Windows operating system core, and WDM＇s driver designing often refers to the IRQL. The IRQL＇s essence in the WIM driver designing based on the Windows and the influence on the thread schedule by the IRQL are analyzed, the differences and relationship between IRQL and CPU ring level, thread priority and hardware IRQ are researched, the theory of the realizing spin lock by the IRQL is analyzed.
