yann@121: 
yann@1: config PARALLEL_JOBS
yann@1:     int
yann@1:     prompt "Number of parallel jobs"
yann@1:     default 1
yann@1:     help
yann@1:       Number of jobs make will be allowed to run concurently.
yann@1:       Set this higher than the number of processors you have, but not too high.
yann@1:       A good rule of thumb is twice the number of processors you have.
yann@1:       
yann@1:       Enter 1 (or 0) to have only one job at a time.
yann@1: 
yann@1: config LOAD
yann@1:     int
yann@1:     prompt "Maximum allowed load"
yann@1:     default 0
yann@1:     help
yann@1:       Specifies that no new jobs should be started if there are others jobs
yann@1:       running and the load average is at least this value.
yann@1:       
yann@1:       Makes sense on SMP machines only.
yann@1:       
yann@1:       Enter 0 to have no limit on the load average.
yann@1:       
yann@1:       Note: only the integer part of the load is allowed here (you can't enter
yann@1:             0.75 for example).
yann@1: 
yann@1: config NICE
yann@1:     int
yann@1:     prompt "Nice level"
yann@1:     default 0
yann@1:     range 0 19
yann@1:     help
yann@1:       Renices the build process up.
yann@1: 
yann@1: config USE_PIPES
yann@1:     bool
yann@1:     prompt "Use -pipe"
yann@1:     default y
yann@1:     help
yann@1:       Use gcc's option -pipe to use pipes rather than temp files when building
yann@1:       the toolchain.
yann@805: 
yann@805: config CONFIG_SHELL_ASH
yann@805:     bool
yann@805:     prompt "Use 'ash' as CONFIG_SHELL"
yann@805:     default n
yann@805:     help
yann@805:       Use /bin/ash as the shell used by ./configure scripts.
yann@805:       
yann@805:       ./configure scripts make intensive use of calling a sub-shell, and the
yann@805:       traditional bash is slow, whereas ash is faster.
yann@805:       
yann@805:       Saying 'y' here should be safe enough, but some components may not
yann@805:       accept using a shell other than bash (this is most probably true for
yann@805:       old versions). If you have trouble, say 'n' here and see if it fixes it.
