I've been debugging an assert failure when using HeapGuard on AArch64. A
call to FreePages in SmbiosDxe is failing because the memory is aligned
to 0x1000 instead of 0x10000 as defined by
RUNTIME_PAGE_ALLOCATION_GRANULARITY.
I'm enabling HeapGuard by setting the PCDs to the following values:
gEfiMdeModulePkgTokenSpaceGuid.PcdHeapGuardPropertyMask|0x0F
gEfiMdeModulePkgTokenSpaceGuid.PcdHeapGuardPageType|0xC00000000000FFFF
gEfiMdeModulePkgTokenSpaceGuid.PcdHeapGuardPoolType|0xC00000000000FFFF
Hi Rebecca,
Are you including this commit:
https://github.com/tianocore/edk2/commit/00b51e0d78a547dd78119ec44fcc74a01b6f79c8?
Can you share some more details on where this is failing? I.e. what
assert is getting tripped? Presumably without HeapGuard enabled, you
aren't seeing the failure?
Are you hitting this case:
https://github.com/tianocore/edk2/blob/59f024c76ee57c2bec84794536302fc770cd6ec2/MdeModulePkg/Core/Dxe/Mem/Page.c#L1570-L1573?
Does this repro on ArmVirtPkg?
Thanks,
Oliver
