[gem5-users] ARM+RUBY+GARNET in FS mode
Hello, I am trying to get the garnet system up on ARM in fs mode with the following : scons build/ARM/gem5.fast PROTOCOL=MI_example ./build/ARM/gem5.fast configs/example/fs.py --kernel=/home/mayya/gem5/linux/vmlinux --machine-type=VExpress_GEM5_V1 --dtb-file=/home/mayya/gem5/system/arm/dt/armv8_gem5_v1_16cpu.dtb --disk-image=linaro-minimal-aarch64.img --num-cpus=16 --cpu-type=AtomicSimpleCPU --mem-size=512MB --ruby --num-dirs=16 --network garnet2.0 --topology Mesh --mesh-rows 4 --numa-high-bit=28 *But*fatal: The MI_example protocol cannot implement Load/Store Exclusive operations. Multicore ARM systems configured with the MI_example protocol will not work properly. Therefore I am trying to build with other cache coherence PROTOCOLS Does anybody have an idea of what could be supported if you have tried something similar? I get warnings : warn: You are trying to use Ruby on ARM, which is not working properly yet. So any input to fix this and have a working combination would greatly help. Thank you in advance, Regards, Sahana Prasad ___ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
Re: [gem5-users] Is the dtb file important for FS simulation?
Hello Andreas,Haeyoon Cho, Andreas , thanks thi worked for me too. fs simulation on Arm with 16 CPUS. I wanted to know if any one of you have tried GARNET on ARM? Inputs would really be helpful. I want to simulate a 4*4 mesh garnet system on ARM Thank you in advance.
