Hi Jiewen,

I just noticed that building OvmfIa32.dsc with -D SMM_REQUIRE, and then
running the 32-bit guest with 4G RAM (of which 2GB are placed in 64-bit
address pace), the guest crashes when PiSmmCpuDxeSmm tries to protect
the memory range at 4GB. Please find the log attached (it ends with the
crash).

Is this expected to work?

Thanks
Laszlo
