Are you using the fs_bitLITTLE.py script?
Big/Little CPUs should be grouped under the bigCluster/littleCluster SimObjects.

This should be visible in both config.ini and in the stats file (e.g.)

[…]
system.bigCluster.clk_domain.clock                500                       # 
Clock period in ticks (Tick)
system.bigCluster.cpus0.numCycles              627273                       # 
Number of cpu cycles simulated (Cycle)
system.bigCluster.cpus0.numWorkItemsStarted            0                       
# Number of work items this cpu started (Count)
system.bigCluster.cpus0.numWorkItemsCompleted            0                      
 # Number of work items this cpu completed (Count)

So you should be able to match stats with the correct cpu type…

Is this what you meant?

Kind Regards

Subject: [gem5-users] Identify ARM Big/Little CPU

I am running ARM big.Little simulations. (eg. Big=2, Little=2)

I am unaware to identify which CPU0-CPU3 is Big and which is Little.
