This bug is awaiting verification that the linux- hwe-6.2/6.2.0-26.26~22.04.1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

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.
