For test, can we test boot OS (windows/Linux) with PcdCpuStackGuard enabled?
Thank you

> Stack guard feature makes use of paging mechanism to monitor if there's a

> enable/disable this feature. PCD PcdCpuStackSwitchExceptionList and
> PcdCpuKnownGoodStackSize are introduced to configure the required

> If this feature is enabled, DxeIpl will setup page tables and set page where

> Fault exception will be triggered.
>
> In order to make sure exception handler works normally even when the stack
> is corrupted, stack switching is implemented in exception library.

> Due to the mechanism behind Stack Guard, this feature is only avaiable for
> UEFI drivers (memory avaiable). That also means it doesn't support NT32
> emulated platform (paging not supported).

> Validation works include:
> a. OVMF emulated platform: boot to shell (IA32/X64)
> b. Intel real platform: boot to shell (IA32/X64)
