Add metrics taken from Section 1.2 "Performance Measurement" of the Performance Monitor Counters for AMD Family 1Ah Model 00h-0Fh Processors document available at the link below. The recommended metrics are sourced from Table 1 "Guidance for Common Performance Statistics with Complex Event Selects". The pipeline utilization metrics are sourced from Table 2 "Guidance for Pipeline Utilization Analysis Statistics". These are useful for finding performance bottlenecks by analyzing activity at different stages of the pipeline. There are metric groups available for Level 1 and Level 2 analysis.

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.
