The blocked domain can be extended to park PASID of a device to be the DMA blocking state. By this the remove_dev_pasid() op is dropped. Remove PASID from old domain and device GCR3 table. No need to attach PASID to the blocked domain as clearing PASID from GCR3 table will make sure all DMAs for that PASID are blocked.

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 reStructuredText 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.
