This patch uses pthread_getaffinity_np() to narrow down used cores when none of below options is specified: * coremask (-c) * corelist (-l) * and coremap (--lcores) The purpose of this patch is to leave out these core related options when DPDK applications are deployed under container env, so that users do not need decide the core related parameters when developing applications. Instead, when applications are deployed in containers, use cpu-set to constrain which cores can be used inside this container instance. And DPDK application inside containers just rely on this auto detect mechanism to start polling threads. Note: previously, some users are using isolated CPUs, which could be excluded by default. Please add commands like taskset to use those cores. Test example: $ taskset 0xc0000 ./examples/helloworld/build/helloworld -m 1024 Signed-off-by: Jianfeng Tan <jianfeng.tan@intel.com> Acked-by: Neil Horman <nhorman@tuxdriver.com> Acked-by: Bruce Richardson <bruce.richardson@intel.com> |
