## 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

##
## Xanmod-ROG options:
##
## 'amd_pstate' - Setting this variable to 'n' will disable amd-pstate
##                unset/default enables the driver
if [ -z ${amd_pstate+x} ]; then
  amd_pstate=y
fi

## 'no_makeflags_check' - If /etc/makepkg.conf MAKEFLAGS is null or unset we'll throw a big warning
##                        and pause long enough for the user to cancel their build.
##                        Set "no_makeflags_check" to anything to skip this.
if [ -z ${no_makeflags_check+x} ]; then
  makeflags_check=y
fi

## '_O3' -  Enable -O3 optimization - this isn't generally worth much, especially in the face of
##          -march=native (or -march=x86-64-v3) and clang ThinLTO; set _O3 to anything to enable
if [ -n "${_O3+x}" ]; then
  _O3=y
fi

##
## Xanmod options:
##
## 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=93
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

## Choose between GCC and CLANG config (default is GCC)
case "${_compiler,,}" in
  "clang" | "gcc") _compiler=${_compiler,,} ;; # tolower, simplifes later checks
                *) _compiler=gcc            ;; # default to GCC
esac

## Compress modules with ZSTD (to save disk space)
#if [ -z ${_compress_modules+x} ]; then
#  _compress_modules=y
#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
