Some Root Ports on Intel Tiger Lake and Alder Lake systems support the RP Extensions for DPC and the RP PIO Log registers but incorrectly advertise an RP PIO Log Size of zero. This means the kernel complains that: DPC: RP PIO log size 0 is invalid and if DPC is triggered, the DPC driver will not dump the RP PIO Log registers when it should. This is caused by a BIOS bug and should be fixed the BIOS for future CPUs. Add a quirk to set the correct RP PIO Log size for the affected Root Ports.

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.
