<strong>Kernel</strong> <strong>Parameters</strong><br />

In addition, the following text indicates that the option:<br />

BUGS= Relates to possible processor bugs on the said processor.<br />

KNL Is a kernel start-up parameter.<br />

BOOT Is a boot loader parameter.<br />

<strong>Parameters</strong> denoted with BOOT are actually interpreted by the boot loader, and have no<br />

meaning to the kernel directly.<br />

Do not modify the syntax of boot loader parameters without extreme need or<br />

coordination with .<br />

There are also arch-specific kernel-parameters not documented here.<br />

See for example .<br />

Note that ALL kernel parameters listed below are CASE SENSITIVE, and that a<br />

trailing = on the name of any parameter states that that parameter will be entered as<br />

an environment variable, whereas its absence indicates that it will appear as a kernel<br />

argument readable via /proc/cmdline by programs running once the system is up.<br />
