Subject: [PATCH rdma-next 2/3] RDMA/mlx5: Allow DM allocation for sw_owner_v2 enabled devices
Date: Thu,  3 Sep 2020 10:38:56 +0300	[thread overview]
Message-ID: <20200903073857.1129166-3-leon@kernel.org> (raw)
In-Reply-To: <20200903073857.1129166-1-leon@kernel.org>

From: Alex Vesker <valex@nvidia.com>

sw_owner_v2 will replace sw_owner for future devices, this means
that if sw_owner_v2 is set sw_owner should be ignored and DM
allocation is required for sw_owner_v2 devices to function.
