[edk2-devel] gEfiMdeModulePkgTokenSpaceGuid.PcdNullPointerDetectionPropertyMask and ExitBootServices

[Andrew Fish via groups.io]

I think I might have found a case when grub calls ExitBootServices, PcdNullPointerDetectionPropertyMask is TRUE, and grub decided to allocate memory in the guard area….

Is there any code to turn off PcdNullPointerDetectionPropertyMask at ExitBootServices time?

Seems like MemoryProtectionExitBootServicesCallback() should also turn off PcdNullPointerDetectionPropertyMask?

Thanks,

Andrew Fish
