## The following variables can be customized at build time
##
##  Usage:  env _microarchitecture=98 use_numa=n use_tracers=n makepkg -sc
##     or:  makepkg -sc -- _microarchitecture=98 use_numa=n use_tracers=n
##     or:  export use_numa=n use_tracers=n; makepkg -sc

##
## Xanmod options:
##
## Look inside 'choose-gcc-optimization.sh' to choose your microarchitecture
## Valid numbers between: 0 to 99
## Default is: 93 => x86-64-v3
## Good option if your package is for one machine: 98 (Intel native) or 99 (AMD native)
: "${_microarchitecture:=93}"

## Enable -O3 compiler optimizations, may or may not improve performance. Compilation time increases.
## Set variable "_O3" to: n to disable (default)
##                        y to enable
: "${_O3:=n}"

## 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)
: "${use_numa:=y}"

## 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)
: "${use_tracers:=y}"

## Disable the amd_pstate cpufreq driver. Performance may be improved with the generic acpi_cpufreq driver.
## Stock kernels will have this enabled, disabling this driver is less energy efficient.
## Set variable "amd_pstate" to: y to enable (default)
##                               n to disable
: "${amd_pstate:=y}"

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

## Compress modules by default (following Arch's kernel)
## Set variable "_compress_modules" to: n to disable
##                                      y to enable (default)
: "${_compress_modules:=y}"

# 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
: "${_localmodcfg:=n}"

# Tweak kernel options prior to a build via nconfig
_makenconfig=

# 'makeflags_check' - If MAKEFLAGS in /etc/makepkg.conf is null or unset we'll throw a big
#                     warning and pause long enough for the user to cancel their build.
#                     Set "makeflags_check" to n to skip this
#
