[AMD Official Use Only - AMD Internal Distribution Only] 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]. -Matt From: 王彦景 via gem5-users <gem5-users@gem5.org> Sent: Tuesday, July 23, 2024 4:39 AM To: gem5-users@gem5.org Cc: wangyanj...@nudt.edu.cn Subject: [gem5-users] How to overcome the limitation that the DRAM size in the gem5 standard library can only be set to 3GB? Caution: This message originated from an External Source. Use proper caution when opening attachments, clicking links, or responding. 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<https://github.com/gem5/gem5/releases#:~:text=fs.py%20and%20se.py%20deprecated>). However, I am facing a major issue where the gem5 standard library can only configure up to 3GB of DRAM<https://github.com/gem5/gem5/blob/stable/src/python/gem5/components/boards/x86_board.py#L70>. 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?
