When introducing IBM Power8, we failed to clean the cache line size definition. I promised to not forget this issue in this thread with Neil: http://dpdk.org/ml/archives/dev/2014-December/009439.html It is defined in config/defconfig_* mk/machine/*/rte.vars.mk mk/arch/*/rte.vars.mk rte_memory.h rte_kni_common.h It should be defined only in the config files. When we will introduce a configure script, we should be able to detect it. Please Jerin, as ThunderX maintainer, may you help to fix this old mess? Thanks
