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
