Ampere+ (SRIOV based) Nvidia vGPU use kernel's mdev framework and use this kABI to pin all guest memory during VM boot. As HWE kernel (for Ubuntu 22.04) will switch to 5.19 upstream kernel, it will not include this kABI and as a result will break SRIOV based Nvidia vGPU. So, filing this bug to request to have a custom patch in HWE kernel which doesn't remove the support for mdev_set_iommu_device() kABI.
