Subject: [dpdk-dev] [PATCH v1 7/8] common/mlx5: exclude OS dependency in devx commands
Date: Wed, 10 Jun 2020 09:32:32 +0000
Message-ID: <20200610093233.23902-8-ophirmu@mellanox.com> (raw)
In-Reply-To: <20200610093233.23902-1-ophirmu@mellanox.com>

Shared function mlx5_devx_cmd_mkey_create() reads the OS pagesize by
calling a Linux API: 'sysconf(_SC_PAGESIZE)'. Wrap this call with a
shared API 'mlx5_os_get_page_size()' which contains the specific OS
implementation.
