## The following variables can be customized at build time. Use env or export to change at your wish
##
## Example: env _microarchitecture=98 use_numa=n use_tracers=n makepkg -sc
##
## Look inside 'choose-gcc-optimization.sh' to choose your microarchitecture
## Valid numbers between: 0 to 99
## Default is: 0 => generic
## Good option if your package is for one machine: 98 (Intel native) or 99 (AMD native)
if [ -z ${_microarchitecture+x} ]; then
_microarchitecture=0
fi
## Disable NUMA since most users do not have multiple processors. Breaks CUDA/NvEnc.
## Archlinux and Xanmod enable it by default.
## Set variable "use_numa" to: n to disable (possibly increase performance)
## y to enable (stock default)
if [ -z ${use_numa+x} ]; then
use_numa=y
fi
## For performance you can disable FUNCTION_TRACER/GRAPH_TRACER. Limits debugging and analyzing of the kernel.
## Stock Archlinux and Xanmod have this enabled.
## Set variable "use_tracers" to: n to disable (possibly increase performance)
## y to enable (stock default)
if [ -z ${use_tracers+x} ]; then
use_tracers=y
fi
## GCC is the unique compiler supported
if [ -z ${_compiler+x} ]; then
_compiler=gcc
fi
# Compile ONLY used 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 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
