Linux Kernel in a Nutshell

Name

lpj — Set the loops per jiffy.

Synopsis

lpg= n

Specify the loops per jiffy that should be used by the kernel, and thus have the kernel avoid the time-consuming boot-time autodetection of this value. If n is 0, the value will be autodetected as usual.

Warning

On SMP systems, this value will be set on all CPUs, which might cause problems if the different CPUs need different settings. An incorrect value will cause incorrect delays in the kernel, which can lead to unpredictable I/O errors and other breakage. Although unlikely, in the extreme case this might damage your hardware.
