From mboxrd@z Thu Jan 1 00:00:00 1970 From: Cunming Liang Subject: [PATCH v2 10/15] log: fix the gap to support non-EAL thread Date: Wed, 28 Jan 2015 14:59:20 +0800 Message-ID: <1422428365-5875-11-git-send-email-cunming.liang@intel.com> References: <1421914598-2747-1-git-send-email-cunming.liang@intel.com> <1422428365-5875-1-git-send-email-cunming.liang@intel.com> To: dev-VfR2kkLFssw@public.gmane.org Return-path: In-Reply-To: <1422428365-5875-1-git-send-email-cunming.liang-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org> List-Id: patches and discussions about DPDK List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces-VfR2kkLFssw@public.gmane.org Sender: "dev" For those non-EAL thread, *_lcore_id* is invalid and probably larger than RTE_MAX_LCORE. The patch adds the check and allows only EAL thread using EAL per thread log level and log type. Others shares the global log level.
