vdpa/mlx5: Add debugfs subtree Add debugfs subtree and expose flow table ID and TIR number. This information can be used by external tools to do extended troubleshooting. The information can be retrieved like so: $ cat /sys/kernel/debug/mlx5/mlx5_core.sf.1/vdpa-0/rx/table_id $ cat /sys/kernel/debug/mlx5/mlx5_core.sf.1/vdpa-0/rx/tirn Reviewed-by: Si-Wei Liu <si-wei.liu@oracle.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Eli Cohen <elic@nvidia.com> Message-Id: <20221114131759.57883-8-elic@nvidia.com> Signed-off-by: Michael S.

vdpa/mlx5: Add VDPA driver for supported mlx5 devices Add a front end VDPA driver that registers in the VDPA bus and provides networking to a guest. The VDPA driver creates the necessary resources on the VF it is driving such that data path will be offloaded. Notifications are being communicated through the driver. Currently, only VFs are supported. In subsequent patches we will have devlink support to control which VF is used for VDPA and which function is used for regular networking.

vdpa/mlx5: Add shared memory registration code Add code to support registering address space region for the device. The virtio driver can run as either: 1. Guest virtio driver 2. Userspace virtio driver on the host 3. Kernel virtio driver on the host In any case a memory key object is required to provide access to memory for the device. This code will be shared by network or block driver implementations.
