With AMD Last Branch Record Extension Version 2 (LbrExtV2), it is necessary to process the branch records further as hardware filtering is not granular enough for identifying certain types of branches. E.g. to record system calls, one should record far branches. The filter captures both far calls and far returns but the irrelevant records are filtered out based on the branch type as seen by the branch classifier.

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.
