Currently, PCI PASID is enabled alongside PCI ATS when an iommu domain is attached to the device and disabled when the device transitions to block translation mode. This approach is inappropriate as PCI PASID is a device feature independent of the type of the attached domain. Enable PCI PASID during the IOMMU device probe and disables it during the release path.

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.
