The DWC PCIe controller can be used with its internal MSI controller or with an external one such as the GICv3 Interrupt Translation Service (ITS). Add the msi-map properties needed to use the GIC ITS. This will also make Linux switch to the ITS implementation, which allows for assigning affinity to individual MSIs. Note that using the GIC ITS on SC8280XP will cause Advanced Error Reporting (AER) interrupts to be received on errors unlike when using the internal MSI controller. This will specifically lead to notifications about Correctable Errors being logged for the Wi-Fi controller on the Lenovo ThinkPad X13s when ASPM L0s is enabled.

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.
