bash 复制代码
./build/X86_MOESI_hammeryz1wVCBuffer/gem5.opt -d m5out/20250105NoSleepX86_MOESI_hammeryz1wVCBuffer_X86KvmCPUCHKPT/    configs/deprecated/example/fs.py --kernel=/home/yz/.cache/gem5/x86-linux-kernel-4.19.83 --disk=/home/yz/.cache/gem5/x86-parsec      --cpu-type=X86KvmCPU      --num-cpus=64   --ruby   --network=garnet   --topology=Mesh_XY   --mesh-rows=8 --num-dirs=64  --num-l2caches=64  --script=configs/boot/yzhack_back_ckpt.rcS

可能几分钟跑完

bash 复制代码
 ./build/X86_MOESI_hammeryz1wVCBuffer/gem5.opt  -d m5out/used_20250105NoSleepX86_MOESI_hammeryz1wVCBuffer_X86KvmCPUCHKPT/ configs/deprecated/example/fs.py     --checkpoint-restore=1  --checkpoint-dir=/home/yz/myprojects/2024GEM5/parsec-tests/yzmodifiedgem5/m5out/20250105NoSleepX86_MOESI_hammeryz1wVCBuffer_X86KvmCPUCHKPT/ --restore-with-cpu=X86AtomicSimpleCPU   --cpu-type=X86AtomicSimpleCPU     --num-cpus=64   --ruby   --network=garnet   --topology=Mesh_XY   --mesh-rows=8 --num-dirs=64  --num-l2caches=64  --script=configs/yz2023Nov/large/yzjustexit.script

这个调用checkpoint只要几十秒钟,确切一点,在我的10700k上是19秒。

下一步是用kvm的checkpoint 运行cpu-type=X86AtomicSimpleCPU .

bash 复制代码
 ./build/X86_MOESI_hammeryz1wVCBuffer/gem5.opt  -d m5out/used_20250105NoSleepX86_MOESI_hammeryz1wVCBuffer_X86KvmCPUCHKPT/blacksholes configs/deprecated/example/fs.py     --checkpoint-restore=1  --checkpoint-dir=/home/yz/myprojects/2024GEM5/parsec-tests/yzmodifiedgem5/m5out/20250105NoSleepX86_MOESI_hammeryz1wVCBuffer_X86KvmCPUCHKPT/ --restore-with-cpu=X86AtomicSimpleCPU   --cpu-type=X86AtomicSimpleCPU     --num-cpus=64   --ruby   --network=garnet   --topology=Mesh_XY   --mesh-rows=8 --num-dirs=64  --num-l2caches=64  --script=configs/yz2023Nov/large/yzfs_largeparsecblacksholes.script

m5term 那边报错:

"

再次验证以后,发现just exit能运行,blacksholes不行。所以删除kvm的checkpoint。等6号再来。

7好发现,atomic的checkpoint,跑timingsimple依旧类似错误。

重新用timingsimple存checkpoint。
