Subject: [dpdk-dev] [PATCH 1/7] eal: move OS common functions to single file
Date: Wed, 22 Apr 2020 10:27:41 +0300	[thread overview]
Message-ID: <20200422072747.15960-2-talshn@mellanox.com> (raw)
In-Reply-To: <20200422072747.15960-1-talshn@mellanox.com>

From: Tal Shnaiderman <talshn@mellanox.com>

Move common functions between Unix and Windows to eal_config.c.
Those simple functions are getter functions for IOVA, configuration, Multi-process.

Move rte_config and runtime_dir to be defined in a common file.

Signed-off-by: Tal Shnaiderman <talshn@mellanox.com>
