How to complete ForEachLogicalCore () in the driver about hvpp

It doesn't work that way, unfortunatelly. You must issue invept instruction on CPU that the EPT belongs to. Use mp::ipi_call() for this - its basically your "ForEachLogicalCore", except that it runs on IRQL 14.

It's amazing, you are really an energetic and excellent technician, I didn't think I could get your reply in such a short time. I will try the method you proposed

不幸的是，这种方式行不通。您必须在EPT所属的CPU上发出invept指令。为此，使用mp :: ipi_call（）-基本上是您的“ ForEachLogicalCore”，除了它运行在IRQL 14上。

Thank you very much for your previous guidance, but after four hours of hard work, I still cannot use this function to call split_2mb_to_4kb, which will cause the system to crash, and I hope to get your help. Could you please write an example

You cannot use ipi_call with vmexit handler
