Sorry for the delay. Looks OK just a couple of questions... Is it intentional that you have not updated driver-native.c to detect an Octeon 3 CPU? I guess you may be waiting on Octeon 3 being committed to the kernel so you know for sure how the CPU will appear in procinfo? Could you confirm what testing the patch has had?
