[Solved] (Windows)Sleep in kernel driver - CodeProject
https://www.codeproject.com/questions/631671/windows-sleep-in-kernel-driver
Sleep () has very limited value and you can use Google to find out why. Ultimately you need waitable timers. (1) Create a kernel timer via KeInitializeTimer. (2) Set the timer with KeSetTimerEx and use a period of 2s for example. (3) Create a thread in your driver. In the thread, call KeWaitForSingleObject to wait on the timer.

Answer: Not everything that runs on the CPU is schedulable. For example, the top half interrupt handler code is invoked every time the corresponding hardware interrupt comes in (indeed, the hardware simply pauses whatever it was doing before the interrupt came in and jumps the execution to the pr...
