 # GENERIC -- Generic kernel configuration file for FreeBSD/arm64
 #
 # For more information on this file, please read the config(5) manual page,
 # and/or the handbook section on Kernel Configuration Files:
 #
 #    http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-config.html
 #
 # The handbook is also available locally in /usr/share/doc/handbook
 # if you've installed the doc distribution, otherwise always see the
 # FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the
 # latest information.
 #
 # An exhaustive list of options and more detailed explanations of the
 # device lines is also present in the ../../conf/NOTES and NOTES files.
 # If you are in doubt as to the purpose or necessity of a line, check first
