[gem5-users] Re: Ruby in Arm?
Hi Adrian, I don't know to be honest why this is happening in fs.py only. In general, have you tried to recompile the gem5 bootloader or alternatively to download the latest precompiled version?

[gem5-users] Re: Ruby in Arm?
Hi Giacomo, Thanks for your response. I've managed to run the simulator with a single core. However, I cannot do the same with more than one. This is the command I use to boot. ./build/ARM/gem5.opt --outdir m5out/booted_machine_4 configs/example/fs.py --kernel=binaries/vmlinux.arm64 --cpu-type=AtomicSimpleCPU --num-cpus=4 --mem-size=2GB --disk-image disks/gem5-ubuntu16.04-aarch64.img --script configs/boot/hack_back_ckpt.rcS I get the following message in the terminal: [0.048079] smp: Bringing up secondary CPUs ... [1.088619] CPU1: failed to come online [1.088622] CPU1: failed in unknown state : 0x0 [2.145168] CPU2: failed to come online [2.145171] CPU2: failed in unknown state : 0x0 [3.201716] CPU3: failed to come online [3.201719] CPU3: failed in unknown state : 0x0 [3.201737] smp: Brought up 1 node, 1 CPU I do not get this error when using the fs_bigLITTLE.py file. My gem5 version is 21.0.0.0. What could be happening?

That is a legacy warning from fs.py which has been removed in develop branch by: https://gem5-review.googlesource.com/c/public/gem5/+/44509 And will be part of gem5 21.1 > > Can anybody confirm me I can use it or how to properly use it? > > I'm employing this command: > > "./build/ARM/gem5.opt -d m5out/foo configs/example/fs.py --cpu- > type=DerivO3CPU --ruby --num-cpus=4 --caches --l2cache --kernel > binaries/vmlinux.arm64 --restore-with-cpu=DerivO3CPU --dtb > binaries/armv8_gem5_v1_4cpu.dtb --mem-size=2GB --disk-image > disks/gem5-ubuntu16.04-aarch64.img -r 1" That seems a valid command line. FYI I have added a simpler ARM ruby script in develop to use in lieu of fs.py: configs/example/arm/ruby_fs.py That will be also part of 21.1 Kind Regards Giacomo > > Thanks a lot, > Adrián > ___ > gem5-users mailing list -- gem5-users@gem5.org To unsubscribe send an > email to gem5-users- > le...@gem5.org %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
