Subject: [PATCH] vfio/pci: Add driver_managed_dma to the new vfio_pci drivers
Date: Thu, 19 May 2022 20:14:01 -0300	[thread overview]
Message-ID: <0-v1-f9dfa642fab0+2b3-vfio_managed_dma_jgg@nvidia.com> (raw)

When the iommu series adding driver_managed_dma was rebased it missed that
new VFIO drivers were added and did not update them too.

Without this vfio will claim the groups are not viable.

Add driver_managed_dma to mlx5 and hisi.
