However, considering page fault scenarios, which are self-contained but linked to a hardware page table (hwpt), introduces ambiguity. Hwpt can be created with or without a vIOMMU. This raises the question: should the page fault message always report the iommufd device ID, or should the reporting depend on whether the hwpt was created from a vIOMMU?
I think every single event record read from the FD needs to clearly specify what its fields are.
Page fault need to clearly say it's field is a device ID.
