Hello,
(Previous email sent prematurely)
You will need to edit the e820 table, I believe. See here for an example of
how stdlib appends:
https://github.com/gem5/gem5/blob/stable/src/python/gem5/components/boards/x86_board.py#L251
. You probably will need to modify this function too:
https://github.com/gem5/gem5/blob/stable/src/python/gem5/components/boards/x86_board.py#L283
and add a self.mem_ranges[2].

Hi,
I am currently using the gem5 standard library to build system configurations,
as recommended by the gem5 community (with fs.py and se.py being deprecated).
However, I am facing a major issue where the gem5 standard library can only
configure up to 3GB of DRAM. I have attempted to modify x86_board.py by
referring to the address range configurations in fs.py, but my efforts have
been unsuccessful. Could anyone advise me on how to overcome the 3GB DRAM
limitation?
