Subject: [dpdk-dev] [PATCH v9 1/2] eal: move thread affinity functions to new file
Date: Wed,  6 Jan 2021 22:35:52 +0200
Message-ID: <20210106203553.9876-2-talshn@nvidia.com> (raw)
In-Reply-To: <20210106203553.9876-1-talshn@nvidia.com>

Move the definition of the functions
rte_thread_set_affinity and rte_thread_get_affinity
to new file, rte_thread.h

The file will implement generic threading functionality
and will only host threading functions which do not reference
pthread API.
