Hi All, I'm trying to simulate ARM "big.LITTLE" architecture so, I need to simulate two different clusters (the a7 cluster and the a15 cluster) I'm simulating 8 cores
I've tried the following: 1-Modifying the device tree so that 4 cores belong to the first cluster and the other 4 belong to the other cluster (I've used the dvfs_per_core device tree supported with gem5 linux kernel as an example) 2-All cores in the simulation script start as AtomicSimple CPU and 4 of them switch to "DerivO3CPU" and the other 4 switch to "MinorCPU" after entering ROI What happens is that cores fail to boot What am I doing wrong? What should I do to achieve that clustering? Thanks -- *Khaled M. Attia* *T.A. @ Computers & Systems Engineering* *Mansoura University, Egypt* Mob. : +201000736160 email: khaled.3ttia[at]gmail.com
