This option enables a tickless system: timer interrupts will
|
|
only trigger on an as-needed basis both when the system is
|
|
busy and when the system is idle.

help
|
|
This option enables high resolution timer support. If your
|
|
hardware is not capable then this option only increases
|
|
the size of the kernel image.
