That's right. The memory before loading linux kernel is predicable.
To support different size of linux kernel, there are hot discussions in EDK2/QEMU/LinuxKernel communities. There is a summary of the discussion in this link https://edk2.groups.io/g/devel/message/92332

I am also nervous to change in the fundamental memory allocation service (MdeModulePkg/Core/Dxe/Mem).
Another option is that in current stage we accept memories under 4G and so that we can drop this patch (Pool and page functions accept memory when OOM occurs).

What's your thoughts?

Thanks
Min
