[gem5-users] How to use the KVM CPU take simpoint

[kong han via gem5-users]

Hi all,
I am trying to take the simpoint while runing benchmark to get the bbv file, 
but I can’t use the KVM CPU to generate the Simpoint. only the 
NonCachingSimpleCPU is OK, but it will be to slow. How could I solve this 
problem?
I use the gem5 version 20.0.0.3,
My cmd is :
./build/ARM/gem5.opt \
    -d ./m5out/take-simpoint-2/401/  \
    ./configs/example/fs.py  \
    --cpu-type=ArmV8KvmCPU  \
     --simpoint-profile  \
    --simpoint-interval 100000000   \
The fatal is :
fatal: SimPoint generation should be done with atomic cpu.
Thanks.
