Hello Everyone, I have created the checkpoint for booting up Linux image. My command line is """
build/X86/gem5.opt --outdir=/home/abs218/gem5_dir_local/gem5_bl_fs/common_checkpoint_chkpt --stats-file=common_checkpoint_chkpt.simout --dump-config=common_checkpoint_chkpt.ini --redirect-stderr --stderr-file=common_checkpoint_chkpt.e configs/example/fs.py --checkpoint-dir=/home/abs218/gem5_dir_local/gem5_bl_fs/common_checkpoint_chkpt --disk-image=/home/abs218/gem5_dir_local/gem5_bl_fs/intel.img --kernel=/home/abs218/new_fs/gem5/linux-4.8.13/vmlinux --script=./common_checkpoint.rcS --caches --l2cache """ my common_checkpoint.rcS is """ #!/bin/sh /sbin/m5 checkpoint echo "Done :D" /sbin/m5 exit """ I wanted to use this checkpoint and try to run a hello_world benchmark. So I modify my common_checkpoint.rcS script to """ #!/bin/sh ./hello_world echo "Done :D" /sbin/m5 exit """ And my gem5 command line is """ ./build/X86/gem5.opt --outdir=/home/abs218/gem5_dir_local/gem5_bl_fs/common_checkpoint_chkpt --stats-file=common_checkpoint_chkpt_restore.simout --dump-config=common_checkpoint_chkpt_restore.ini configs/example/fs.py --checkpoint-restore=1 --checkpoint-dir=/home/abs218/gem5_dir_local/gem5_bl_fs/common_checkpoint_chkpt --restore-with-cpu=AtomicSimpleCPU --cpu-type=DerivO3CPU --caches --l2cache --disk-image=/home/abs218/gem5_dir_local/gem5_bl_fs/intel.img --kernel=/home/abs218/new_fs/gem5/linux-4.8.13/vmlinux --script=./common_checkpoint.rcS """ But my "system.pc.com_1.device" output after restoring is "" Done :D "" That is, it did not run the hello_world program! I have made no changes to gem5, the commit I am using is " 2a98a994df296f818b05da90ba073d879562da04" My question is: Is it not possible to create a common checkpoint and then run the benchmark using that checkpoint? Are my steps incorrect to create or restore from the checkpoint? Best regards, Abhishek
