2022-08-11vdpa/mlx5: Implement susupend virtqueue callbackEli Cohen
Implement the suspend callback allowing to suspend the virtqueues so they stop processing descriptors. This is required to allow to query a consistent state of the virtqueue while live migration is taking place.

2022-05-31vdpa/mlx5: Add support for reading descriptor statisticsEli Cohen
Implement the get_vq_stats calback of vdpa_config_ops to return the statistics for a virtqueue. The statistics are provided as vendor specific statistics where the driver provides a pair of attribute name and attribute value. Currently supported are received descriptors and completed descriptors. Signed-off-by: Eli Cohen <elic@nvidia.com> Message-Id: <20220518133804.1075129-6-elic@nvidia.com> Signed-off-by: Michael S.

2021-08-11vdpa/mlx5: Fix queue type selection logicEli Cohen
get_queue_type() comments that splict virtqueue is preferred, however, the actual logic preferred packed virtqueues. Since firmware has not supported packed virtqueues we ended up using split virtqueues as was desired. Since we do not advertise support for packed virtqueues, we add a check to verify split virtqueues are indeed supported.

2020-12-04vdpa/mlx5: Make hardware definitions visible to all mlx5 devicesLeon Romanovsky
Move mlx5_vdpa IFC header file to the general include folder, so mlx5_core will be able to reuse it to check if VDPA is supported prior to creating an auxiliary device. As part of this move, update the header file name to mlx5 general naming scheme. Reviewed-by: Parav Pandit <parav@nvidia.com> Signed-off-by: Leon Romanovsky <leonro@nvidia.com>
