### BUILD OPTIONS
# Set these variables to ANYTHING that is not null to enable them
# Tweak kernel options prior to a build via nconfig
_makenconfig=

# Optionally select a sub architecture by number if building in a clean chroot
# Leaving this entry blank will require user interaction during the build
# which will cause a failure to build if using makechrootpkg. Note that the
# generic (default) option is 26.

# Compile ONLY probed modules
# As of mainline 2.6.32, running with this option will only build the modules
# that you currently have probed in your system VASTLY reducing the number of
# modules built and the build time to do it.
#
# WARNING - ALL modules must be probed BEFORE you begin making the pkg!
#
# To keep track of which modules are needed for your specific system/hardware,
# give module_db script a try: https://aur.archlinux.org/packages/modprobed-db
# This PKGBUILD will call it directly to probe all the modules you have logged!
#
# More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed-db

# If you have laptop with optimus and it hangs on boot one solution might be
# to set acpi_rev_override. Yet for this to happen kernel should be compiled
# with `CONFIG_ACPI_REV_OVERRIDE_POSSIBLE`. Set next variable to `y` to enable.
