# 'bmq' - select 'BitMap Queue CPU scheduler'
# 'pds' - select 'Priority and Deadline based Skip list multiple queue CPU scheduler'

# 'cacule-rdb' - select 'CacULE-RDB scheduler'
# 'bore' - select 'Burst-Oriented Response Enhancer'
# 'tt' - select 'Task Type Scheduler by Hamad Marri'

### BUILD OPTIONS

# 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=
# Compile ONLY used modules to VASTLYreduce 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 script a try: https://aur.archlinux.org/packages/modprobed-db
# This PKGBUILD read 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.
