iommufd_fault_iopf_enable has limitation to PRI on PCI/SRIOV VFs because the PRI might be a shared resource and current iommu subsystem is not ready to support enabling/disabling PRI on a VF without any impact on others. However, we have devices that appear as PCI but are actually on the AMBA bus. These fake PCI devices have PASID capability, support stall as well as SRIOV, so remove the limitation for these devices.

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.
