Yeah, since device-dax is the only path to support longterm page pinning for vfio device assignment, testing with device-dax + 1GB pages would be a useful sanity check.
What are the issues with fs-dax and page pinning? Is that limitation something that is permanent and unfixable (by me or anyone)?
I'd like to put a lot more in a DAX/pmem region than just a guest's memory, and having a mountable filesystem would be extremely convenient.
