From: Xiaoyun Li Date: Fri, 8 Sep 2017 03:28:52 +0000 (+0800) Subject: mk: add silvermont to replace atom as a target X-Git-Tag: spdx-start~1850 X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=d2654a6a929c78c9098bd3ebf9aba2267facc066 mk: add silvermont to replace atom as a target The -march=atom flag is for older atom CPUs and don't support SSE4 which is the minimum requirement for DPDK. And in fact, the current atom CPUs support SSE4. So this patch removes atom as a target for DPDK builds and adds a silvermont replacement instead.
