### BUILD OPTIONS
# Set the next two variables to ANYTHING that is not null to enable them
# NUMA is optimized for multi-socket motherboards.
# A single multi-core CPU actually runs slower with NUMA enabled.
# See, https://bugs.archlinux.org/task/31187
_NUMAdisable=y
#enable winesync
_winesync=y
### Set performance governor as default
_per_gov=
### Running with a 2000 HZ, 1000HZ or 500HZ tick rate
_2k_HZ_ticks=
_1k_HZ_ticks=y
_500_HZ_ticks=
### Enable protect file mappings under memory pressure
_mm_protect=y
### Enable Linux Random Number Generator
#_lrng_enable=y
# Tweak kernel options prior to a build via nconfig
_makenconfig=
# Only compile active modules to VASTLY reduce the number of modules built and
# the build time.
#
# To keep track of which modules are needed for your specific system/hardware,
# give module_db a try: https://aur.archlinux.org/packages/modprobed-db
# This PKGBUILD reads the database kept if it exists
#
# More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed-db
_localmodcfg=
# Use the current kernel's .config file
# Enabling this option will use the .config of the RUNNING kernel rather than
# the ARCH defaults. Useful when the package gets updated and you already went
# through the trouble of customizing your config options. NOT recommended when
# a new kernel is released, but again, convenient for package bumps.
