[dpdk-dev] multi-process shared memory on PPC

["Xueming(Steven) Li" <xuemingl@mellanox.com>]

Hi all,

I'm testing multi-process example on PowerPC system, looks like shared memory not working properly.
Below are the error and debug info of the first multi-process example 'simple_mp' (works as expected on X86):

// Build DPDK, master branch
# make T=ppc_64-power8-linuxapp-gcc -j160 -C examples/multi_process/simple_mp/
# examples/multi_process/simple_mp/build/simple_mp  -w 0:0.0  --proc-type=primary -l 1-2 --socket-mem 256,256,0,0,0,0,0,0,0,0,0,0,0,0,0,0,256,256
APP: Finished Process Init.
