Hi, I try to add ruby support for arm full system. I define a function named
makeArmRubySystem in FSConfig.py as following and add it to ruby_fs.py. I can
successfully boot 1 cpu, While when I try to boot 4 cpus, it throws a kernel
panic and shuts down cpu1, cpu2 and cpu3. Can someone give me some guidence on
ruby for arm full system? Thanks in andvance.
