Subject: correct way to reserve memory from PrePi?
Date: Wed, 14 Dec 2016 11:02:43 +0100	[thread overview]
Message-ID: <CAN9vWDJ+1Ti69tFmEWo+z__f6aTGmpXGLhcTXEmeNOt8SAi1NQ@mail.gmail.com> (raw)

I tried both BuildResourceDescriptorHob and BuildMemoryAllocationHob
but apparently they don't have any effect.
When I look at the output of the shell's memmap command there aren't
any reserved/unavailable pages.

Furthermore, when using AllocatePages with one of the physical
addresses which I've reserved it succeeds which means that it's not
just a problem of how the memmap command works.

Am I doing something wrong or is this a bug?

Thanks
Michael
