## 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)

## Disable NUMA since most users do not have multiple processors. Breaks CUDA/NvEnc.
|
|
## Archlinux and Xanmod enable it by default.

|
|
## y to enable (stock default)

## For performance you can disable FUNCTION_TRACER/GRAPH_TRACER. Limits debugging and analyzing of the kernel.

## Stock Archlinux and Xanmod have this enabled.

## y to enable (stock default)
