According to the CXL Specification Revision 3.2, Section 8.2.10.2.1.2, Table 8-58 (DRAM Event Record), the CVME (Corrected Volatile Memory Error) Count field is valid under the following conditions: 1. The Threshold Event bit is set in the Memory Event Descriptor field, and 2. The CVME Count must be greater than 0 for events where the Advanced Programmable Threshold Counter has expired. Additionally, if the Advanced Programmable Corrected Memory Error Counter Expire bit in the Memory Event Type field is set, then the Threshold Event bit in the Memory Event Descriptor field shall also be set. Add validity checks for the above conditions while reporting the event to the userspace.

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.
