gem5 怎么跑coremark - Githubissues

qqli579 commented 7 months ago

用你们提供的配置参数跑会错误。参数如下：

                "$gem5_home/build/RISCV/gem5.fast \
                    $gem5_home/configs/example/fs.py\
                    --xiangshan-system \
                    --bare-metal \
                    --cpu-type=DerivO3CPU \
                    --mem-size=8GB \
                    --caches --cacheline_size=64 \
                    --l1i_size=64kB --l1i_assoc=8 \

                    --l3cache --l3_size=16MB --l3_assoc=16 \

                    --l2-hwp-type=WorkerPrefetcher \
                    --l2-to-l3-pf-hint \
                    --l3-hwp-type=WorkerPrefetcher \
                    --mem-type=DRAMsim3 \
                    --dramsim3-ini=$gem5_home/ext/dramsim3/xiangshan_configs/xiangshan_DDR4_8Gb_x8_3200_2ch.ini \

                    --command-line='0x0 0x0 0x66 0 7 1 2000' |& tee run.log" Enter

报下面的错误

你用的是fs.py的，但是参数风格是se.py的参数风格，你在尝试从从gem5的命令行给应用传参数。但是，fs不支持从gem5的命令行给应用传参数。

关于“gem5 怎么跑coremark ”，本项目目前只支持和香山处理器一样的方式运行：

要么是不带参数的bare metal core mark，用这里的方法运行：

https://github.com/OpenXiangShan/GEM5/blob/6a85ffb479c8c1ecff432ddd5801216b4e829580/util/warmup_scripts/simple_gem5.sh#L74C1-L77C7
要么生成香山自定义的全系统仿真的checkpoint，如何生成请看文档：https://github.com/OpenXiangShan/GEM5?tab=readme-ov-file#produce-rvgcpt-checkpoints-with-nemu
