Can I suggest you to have a look at configs/example/memtest.py? The script is using a Noncoherent cache as LLC.
Maybe this would help you on how to attach it. Otherwise we were running regressions using a Noncoherent cache in the past. https://gem5-review.googlesource.com/c/public/gem5/+/22683/2/tests/configs/base_config.py#b280 (This is not happening anymore, but feel free to take the script as an inspiration) Giacomo ________________________________ From: gem5-users <[email protected]> on behalf of 616653241 <[email protected]> Sent: 19 December 2019 01:43 To: gem5-users <[email protected]> Subject: [gem5-users] 回复： ask for help about simulate with noncherentcahe Hi,Abhishek, Thank you for your answer. But, I'm a beginner， and I still dont know how to do it. I just modified the caches.py and the two_level.py Script( see the attached files). But I got a error says "Non-coherent cache received functional snoop request". It may should be in the LLC, but I dont know how to do it? So, can you give some advice? Thank you again. ------------------ 原始邮件 ------------------ 发件人: "Abhishek Singh"<[email protected]>; 发送时间: 2019年12月19日(星期四) 凌晨1:09 收件人: "gem5 users mailing list"<[email protected]>; 主题: Re: [gem5-users] ask for help about simulate with noncherentcahe Hi yuan, In order to that, you need to call non-coherent cache instead of cache in config/common/Caches.py file. From my experience I am able to use LLC as non coherent cache. Please note this is how I used in classic cache model.
