When PCIe AER is in FW-First, OS should process CXL Protocol errors from CPER records. Introduce support for handling and logging CXL Protocol errors. The defined trace events cxl_aer_uncorrectable_error and cxl_aer_correctable_error trace native CXL AER endpoint errors. Reuse them to trace FW-First Protocol errors. Since the CXL code is required to be called from process context and GHES is in interrupt context, use workqueues for processing. Similar to CXL CPER event handling, use kfifo to handle errors as it simplifies queue processing by providing lock free fifo operations. Add the ability for the CXL sub-system to register a workqueue to process CXL CPER protocol errors.

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.
