[dpdk-dev] Minimum Supported x86 microarchitecture

Hi,

The recent reimplementation of rte_memcpy in DPDK v2.0.0 seems to have a placed an implicit floor on the microarchitecture/Instruction set supported by DPDK.

For example, I can't compile head of OVS against DPDK 2.0 with gcc without passing the 'msse3' flag; this points to an implicit minimum  supported CPU of 'core2'. More discussion on same is available here: http://openvswitch.org/pipermail/dev/2015-April/053523.html

Can anyone confirm or deny this, and is/should it be documented?

Thanks in advance,
Mark
