# ML1 - [PATCH V3 00/14] blk-mq-sched: improve SCSI-MQ performance: https://marc.info/?l=linux-block&m=150376523128516&w=2

# NUMA is optimized for multi-socket motherboards. A single multi-core CPU can
# actually run slower with NUMA enabled. Most users will want to set this option
# to enabled ... in other words, do not use NUMA on a single CPU system.
#
# See, https://bugs.archlinux.org/task/31187
_NUMAdisable=y
# 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
_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.
