# GENERIC -- Generic kernel configuration file for FreeBSD/RISC-V
#
# For more information on this file, please read the config(5) manual page,
# and/or the handbook section on Kernel Configuration Files:
#
#    https://docs.freebsd.org/en/books/handbook/kernelconfig/#kernelconfig-config

# 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 (https://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
