Help¶

This module implements a kernel device driver for the Xtensa processor and provides the standard “system clock driver” interfaces. If unchecked, no timer will be used. If checked it will use either an internal timer (default option) or an external timer. In that case one shall unselect XTENSA_INTERNAL_TIMER and define XTENSA_TIMER_IRQ and XTENSA_TIMER_IRQ_PRIORITY.

Direct dependencies¶

XTENSA

(Includes any dependencies from if’s and menus.)

Defaults¶

“y” if XTENSA
