Dear gem5 community,

I am running configs/example/gem5_library/arm-ubuntu-run.py to simulate a multi-core architecture. I could successfully boot up the system, however only one CPU was brought up. Does anyone know what the problem is? Are there some parameters to configure this?

By the way, the config.dot.pdf shows 2 cores in the simulated system.

Here are some related outputs from the terminal:

Best regards,
Congwu

Hi Hoa,

Thanks for your information! It now can boot up multiple cores.

However the system cannot start up successfully, it shows warn: context 1: 100000 consecutive store conditional failures, have you ever seen this warning?

The configurations I use are:

  1. ruby system, SimplePtP topology

  2. 8 timing cores, Mesi_Two_Level cache hierarchy

  3. VExpress_GEM5_V2 platform

The command I use is: ./build/ARM_MESI_TWO_LEVEL/gem5.opt configs/example/gem5_library/arm-ubuntu-run.py.

Regards,

Congwu Zhang
