Subject: Is there an ACPI solution for ARM (or other) platforms that don't have DRAM under 4 GiB?
Date: Thu, 18 Mar 2021 18:47:41 -0700 [thread overview]
Message-ID: <814F375B-BF55-44E3-8E11-8C322ACA26C6@apple.com> (raw)
Some one was asking me this question and I did not know the answer? It looks like the stock ACPI stack needs memory under 4 GiB to fill in 32-bits as it was the 1990’s when that got written down. Is there support on TianoCore to implement ACPI on a platform that does not have memory < 4 GiB in its address map?
Thanks,
Andrew Fish
