RE: [PATCH v6 08/14] iommufd/selftest: Require vdev_id when attaching to a nested domain

From: Nicolin Chen nicolinc@nvidia.com Sent: Saturday, January 25, 2025 8:31 AM

When attaching a device to a vIOMMU-based nested domain, vdev_id must be present. Add a piece of code hard-requesting it, preparing for a vEVENTQ support in the following patch. Then, update the TEST_F.

A HWPT-based nested domain will return a NULL new_viommu, thus no such a vDEVICE requirement.
