RE: [PATCH v5 4/4] vfio: Support IO page table replacement

From: Nicolin Chen nicolinc@nvidia.com Sent: Thursday, March 23, 2023 4:33 PM

Now both the physical path and the emulated path should support an IO page table replacement. Call iommufd_device_replace/iommufd_access_replace(), when vdev->iommufd_attached is true.

Also update the VFIO_DEVICE_ATTACH_IOMMUFD_PT kdoc in the uAPI header.
