From: Anatoly Burakov Date: Tue, 13 Mar 2018 17:42:35 +0000 (+0000) Subject: eal: add internal flag of init completed X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=a99c96e96ad3;p=dpdk.git eal: add internal flag of init completed Currently, primary process initialization is finalized by setting the RTE_MAGIC value in the shared config. However, it is not possible to check whether secondary process initialization has completed. Add such a value to internal config.
