The HWPT is always linked to an IOAS and once a HWPT exists its domain should be fully mapped. This ended up being split up into device.c during a two phase creation that was a bit confusing. Move the iopt_table_add_domain() into iommufd_hw_pagetable_alloc() by having it call back to device.c to complete the domain attach in the required order. Calling iommufd_hw_pagetable_alloc() with immediate_attach = false will work on most drivers, but notably the SMMU drivers will fail because they can't decide what kind of domain to create until they are attached. This will be fixed when the domain_alloc function can take in a struct device.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
