[gem5-users] system.cpu

[Javed Osmany]

Hello

I have a simple system simulation configuration script where I set  system.cpu:

system.cpu = O3_ARM_v7a.O3_ARM_v7a_3()

I then try to print this to confirm and then furthermore set the 
system.mem_mode depending upon the cpu type being used.

However, when I try

print ("System CPU type is: %s" % (system.cpu))

I am getting

System CPU type is: <orphan System>.cpu <== Not able to access system.cpu ??

This would then explain why further on the following check are not working:

if (system.cpu == "AtomicSimpleCPU()"):
    system.mem_mode = 'atomic'
else:
    system.mem_mode = 'timing'


if (system.cpu == "O3_ARM_v7a.O3_ARM_v7a_3()"):
    print ("CPU model is O3_ARM_v7a\n")
    system.cpu.icache = O3_ARM_v7a.O3_ARM_v7a_ICache()
    system.cpu.dcache = O3_ARM_v7a.O3_ARM_v7a_DCache()
    system.cpu.PageTableWalkerCache = O3_ARM_v7a.O3_ARM_v7aWalkCache()
    system.l2cache = O3_ARM_v7a.O3_ARM_v7aL2()

Any pointers?

Tks in advance

Best regards

J.Osmany
