Parsec checkpoint example: https://github.com/arm-university/arm-gem5-rsk/blob/aa3b51b175a0f3b6e75c9c856092ae0c8f2a7cdc/parsec_patches/xcompile-patch.diff#L188 Some fs.py gotchas: https://stackoverflow.com/questions/49011096/how-to-switch-cpu-models-in-gem5-after-restoring-a-checkpoint-and-then-observe-t/49673265#49673265 I first recommend that you first play a bit with the "m5 checkpoint" on the m5 guest tool + the fs.py -r option, example: https://github.com/cirosantilli/linux-kernel-module-cheat/tree/2852fe1989a6f1ab546e9a4fa88724423b3949f5#gem5-checkpoint > Thanks, Bryce Patel > > _______________________________________________ > gem5-users mailing list > gem5-users@gem5.org > http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users _______________________________________________ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
