[dpdk-dev] non-x86 ? Re: Would DPDK run on AMD processors

hi Derek, we completed a DPDK port onto the Tilera's TILE-GX architecture 'Natively' for a customer. Specifically it was on the Gx-36 (36 Tiles) PCIe card. Their team is able to directly take their Host DPDK apps (NFV modules and tunnels generators) and reuse them on the TileNcore-36 PCIe

[dpdk-dev] [PATCH 0/6] Clang compilation support on FreeBSD and Linux

This patch set enables clang compilation on FreeBSD and Linux. It includes patches to fix a number of compilation errors thrown up by clang, and then adds in the appropriate toolchain makefiles and compile-time configurations. This set has been tested with clang v3.3 on FreeBSD 10 and clang v3.4 o

[dpdk-dev] [PATCH 3/6] mk: Ensure correct detection of SSE4.2 on FreeBSD

Add a special case to the native target makefile, where we check if -march=native shows SSE4.2 support. If it does not, then not everything may build, so we check if the hardware supports SSE4.2, and use a corei7 target explicitly to get the SSE4.2 support. Signed-off-by: Bruce Richardson --- mk

Thanks Keith. we will try to enable CentOS in our daily build test. But I has a little concern about Ubuntu 14. We enabled latest UB14 with kernel 3.13.0-24 at this may. It seems that UB LTS will upgrade Linux kernel to 3.13.0-30. But we don't know when it upgrade, and it will cost a lot of effort
