Subject: SetMemorySpaceAttributes with EFI_MEMORY_XP
Date: Mon, 20 Mar 2017 11:32:58 +0100	[thread overview]
Message-ID: <CAN9vWDLTEQt7hrkKZqMUWifjTR8=fZ+e2_vEGOY9npKDW-L+jQ@mail.gmail.com> (raw)

Hi,

I didn't test ArmVirtQemuKernel but I'm trying to use some of the code
for another platform.
So does this call ever succeed with PcdDxeNxMemoryProtectionPolicy
being enabled?
https://github.com/tianocore/edk2/blob/76874be3d411bf8daac051718e20932e0bf97d70/ArmVirtPkg/HighMemDxe/HighMemDxe.c#L95
Status = gDS->SetMemorySpaceAttributes (CurBase, CurSize, Attributes);

Neither the memory that was added by this Dxe nor the one added
automatically by GCD has the EFI_MEMORY_XP capability which causes
SetMemorySpaceAttributes to return EFI_UNSUPPORTED.

Thanks
Michael
