This feature makes use of paging mechanism to add a hidden (not present)
page just before and after the allocated memory block. If the code tries
to access memory outside of the allocated part, page fault exception will
be triggered.
This feature is controlled by three PCDs:
gEfiMdeModulePkgTokenSpaceGuid.PcdHeapGuardPropertyMask
gEfiMdeModulePkgTokenSpaceGuid.PcdHeapGuardPoolType
gEfiMdeModulePkgTokenSpaceGuid.PcdHeapGuardPageType
BIT2 and BIT3 of PcdHeapGuardPropertyMask can be used to enable or disable
memory guard for SMM page and pool respectively. PcdHeapGuardPoolType and/or
PcdHeapGuardPageType are used to enable or disable guard for specific type
of memory. For example, we can turn on guard only for EfiRuntimeServicesCode
and EfiRuntimeServicesData by setting the PCD with value 0x60.
Pool memory is not ususally integer multiple of one page, and is more likely
less than a page. There's no way to monitor the overflow at both top and
bottom of pool memory. BIT7 of PcdHeapGuardPropertyMask is used to control
how to position the head of pool memory so that it's easier to catch memory
overflow in memory growing direction or in decreasing direction.
