The present implementation is only for x86. Other architectures need adjustments for querying presence of EFI. Xen's EFI support is also quite troublesome on non-x86. This is being slowly remedied, but until in better shape the EFI clock functionality should be disabled. Reviewed by: royger Differential Revision: https://reviews.freebsd.org/D31065

# MINIMAL -- Mostly Minimal kernel configuration file for FreeBSD/amd64
|
|
#
|
|
# Many definitions of minimal are possible. The one this file follows is
|
|
# GENERIC, minus all functionality that can be replaced by loading kernel
|
|
# modules.
|
|
#
|
|
# Exceptions:
|
|
# o While UFS is buildable as a module, the current module lacks
|
|
# some features (ACL, GJOURNAL) that GENERIC includes.
|
|
# o acpi as a module has been reported flakey and not well tested, so
|
|
# is included in the kernel.
|
|
# o (non-loaded) random is included due to uncertainty...
|
|
# o Many networking things are included
|
|
#
|
|
# For now, please run changes to these list past imp@freebsd.org
|
|
#
|
|
# 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

# FreeBSD World Wide Web server (https://www.FreeBSD.org/) for the

# An exhaustive list of options and more detailed explanations of the
|
|
# device lines is also present in the ../../conf/NOTES and NOTES files.
