Subject: [PATCH 5.9 032/105] vdpa: mlx5: fix vdpa/vhost dependencies
Date: Mon, 14 Dec 2020 18:28:06 +0100 [thread overview]
Message-ID: <20201214172556.826040460@linuxfoundation.org> (raw)
In-Reply-To: <20201214172555.280929671@linuxfoundation.org>
From: Randy Dunlap <rdunlap@infradead.org>
[ Upstream commit 98701a2a861fa87a5055cf2809758e8725e8b146 ]
drivers/vdpa/mlx5/ uses vhost_iotlb*() interfaces, so select
VHOST_IOTLB to make them be built.
However, if VHOST_IOTLB is the only VHOST symbol that is
set/enabled, the object file still won't be built because
drivers/Makefile won't descend into drivers/vhost/ to build it,
so make drivers/Makefile build the needed binary whenever
VHOST_IOTLB is set, like it does for VHOST_RING.
Fixes these build errors:
ERROR: modpost: "vhost_iotlb_itree_next" [drivers/vdpa/mlx5/mlx5_vdpa.ko] undefined!
ERROR: modpost: "vhost_iotlb_itree_first" [drivers/vdpa/mlx5/mlx5_vdpa.ko] undefined!
Fixes: 29064bfdabd5 ("vdpa/mlx5: Add support library for mlx5 VDPA implementation")
Fixes: aff90770e54c ("vdpa/mlx5: Fix dependency on MLX5_CORE")
