kconfig( <strong>1M</strong>) kconfig(IM)<br />

NAME<br />

kconfig - tune kernel parameters for work-load optimization<br />

SYNOPSIS<br />

/ etc/kconfig [-a [-v] [-V]] [-nnamelist]<br />

DESCRIPTION<br />

kconfig manipulates an A/<strong>UX®</strong> kernel code file for changing<br />

system parameters.<br />

Note: It is not recommended that this utility be used unless<br />

you know exactly what you are doing. Incorrect use<br />

can cause system failures.<br />

kconfig can be used to either list or change the system parameters<br />

listed later in the section "<strong>System</strong> Parameters."<br />

Note that kconfig does not change parameters of the running<br />

kernel, just the image on the disk. You must then run<br />

shutdown(IM) <strong>and</strong> reboot(IM) for the changes to be effective.<br />

FLAG OPTIONS<br />

kconfig interprets the following flag options:<br />

-a<br />

-v<br />

-v<br />

-n name list<br />

List the current values of the parameters in the<br />

kernel object file namelist.<br />

Use with the -a flag option to produce verbose<br />

(commented) output.<br />

Use with the -a flag option to print the current<br />

version of the kernel object file namelist.<br />

Specify which kernel object file is being<br />

modified (the default is / unix).<br />

If -a is used, kconfig displays the parameters <strong>and</strong> exits. If-a<br />

is not used, st<strong>and</strong>ard input is read for a list of changes. You can<br />

specify one change per input line of the form<br />

PARAM value<br />

PARAM += value<br />

P ARAM -= value<br />

where P ARAM is one of the parameter names (listed later in the<br />

section "<strong>System</strong> Parameters") <strong>and</strong> the value is either a decimal<br />

constant or a hexadecimal constant preceded by Ox.<br />
