Hi, I want to boot up Linux with X86KvmCPU and switch to TimingCpu to run some benchmarks, and I needed to run them with garnet interconnection network. I’m planning to do switching via checkpoint (loading checkpoint with TimingCPU).
Following is the command I used to run gem5 in full system mode and create the checkpoint. The details on versions can be found at the end. ./build/X86/gem5.opt configs/example/fs.py --disk-image=dist/x86-ubuntu.img --kernel=dist/vmlinux-4.4.186 --num-cpus=4 --num-dirs=4 --cpu-type=X86KvmCPU --cpu-clock=2GHz --caches --l1d_size=16kB --l1i_size=16kB --l2cache --num-l2cache=4 --mem-type=SimpleMemory --mem-size=2GB --ruby --network=garnet --topology=Mesh_XY --mesh-rows=2 --script=config/boot/hack_back_ckpt.rcS system.pc.com_1.device shows the last message as "Checkpointing simulation..." and I can see a folder cpt.<clocknumber> created at m5out directory. But the simulation is hanging there for more than two hours. I would like to know : 1. Is there anything I'm doing wrong or missing or does checkpointing usually take hours like this? 2. Does checkpointing works with KvmCPU ? 3. Is there a better way to do fast forwarding without using checkpoints? (I cannot use new gem5 standard library because it does not support garnet, therefore I need to use fs.py) gem5 version : 22.0.0.1 disk image : x86-ubuntu-18.04-img from the gem5 resources : https://resources.gem5.org/resources/x86-ubuntu-18.04-img?database=gem5-resources&version=1.0.0 kernel : x86-linux-kernel-4.4.186 from gem5 resources : https://resources.gem5.org/resources/x86-linux-kernel-4.4.186?version=1.0.0 Regards, Hansika Weerasena Hansika Weerasena
