The Qualcomm SCP firmware in X1E machines like the Lenovo ThinkPad T14s does not set the FastChannel supported attribute bit for PERF_LEVEL_GET but crashes when falling back to regular messaging. Use the new SCMI quirk framework to force FastChannel initialisation for this implementation. Note that we can add an upper bound on the version matching when we learn which version has a fix (or limit matching using a SoC compatible string in the unlikely event that always enabling FC causes trouble somewhere).

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.
