Hi gem5 users, Do ruby memory model works with arm in gem5 ? I am following below steps to compile and run: Compile: scons build/ARM/gem5.opt PROTOCOL=MESI_Two_Level RUBY=True run: build/ARM/gem5.opt --outdir=/home/vpathak/gem5_git/gem5/m5out_ruby configs/example/fs.py --checkpoint-restore=1 --restore-with-cpu=detailed --script=/home/vpathak/gem5_git/gem5/configs/boot/dgemm.rcS --kernel=/home/vpathak/gem5_git/full-system-images/binaries/vmlinux.aarch64.20140821 --machine-type=VExpress_EMM64 --dtb-file=/home/vpathak/gem5_git/full-system-images/binaries/vexpress.aarch64.20140821.dtb --disk-image=/home/vpathak/gem5_git/full-system-images/disks/aarch64-ubuntu-trusty-headless.img --cpu-type=detailed --arm-iset=aarch64 --num-cpus=1 --cpu-clock=3GHz --ruby But I am getting below error: AttributeError: object 'LinuxArmSystem' has no attribute '_dma_ports' I looks into the code and found, unlike x86, makeArmSystem() do not initialize test_sys._dma_ports. Am I doing some mistake? Please help in resolving this issue. Thanks in advance for your time. -- with regards, Virendra Kumar Pathak

Hi, After searching the mailing list, I found Andreas Hansson comment "Ruby does not work with ARM (due to assumptions about the memory layout). Thus, stay with the classic memory system" http://www.mail-archive.com/gem5-users%40gem5.org/msg11914.html - Sun, 05 Jul 2015 Could some one please confirm if issue is still present or it was solved in recent commits. Thanks in advance for you time.

Hello Pathak, currently, ARM has no interest in the Ruby memory subsystem. You can check Andreas Hansson's presentation here: http://www.m5sim.org/wiki/images/f/f7/2015_ws_02_hansson_gem5_workshop_2015.pdf There is a very old patch to add Ruby support for ARM (2012): http://reviews.gem5.org/r/1191/ This patch will not work with the VExpress_EMM architecture AFAIK.

Hi all, Rodrigo, I think you’ve gotten the wrong end of the stick. Ruby definitely has a number of technical issues, but if someone is happy to invest time in addressing them that is of course welcome. For most users I would suggest staying with the classic memory system though.
