ARM big.LITTLE Performance Counters

Hi,

I have recently purchased an Odroid XU3 development board which utilizes Samsung Exynos5422. The Linux that accompanies this product has kernel 3.10.9. When I try to read performance counters, the values printed by perf stat are all <not counted>. I was wondering if there is a solution to this problem.

I would really appreciate it if you let me know whether there is a solution to address this problem. If there is not a solution yet, is there anyway I could contribute to address this issue?
