Hi again ;),

Yes, Ruby should support any cacheline size (at least as long as it is a power 
of two).
And yes, you need to change the parameter O3CPU.fetchBufferSize and defaulted 
to 64 bytes. Not sure if it has any other implications but O3_ARM_v7a_3 sets it 
to 16 for instance.

Regards,
Gabriel
