CONFIG_CAVS_TIMER¶
CAVS DSP Wall Clock Timer on Intel SoC
Type: bool
Help¶
The DSP wall clock timer is a timer driven directly by
external oscillator and is external to the CPU core(s).
It is not as fast as the internal core clock, but provides
a common and synchronized counter for all CPU cores (which
is useful for SMP).
Direct dependencies¶

(Includes any dependencies from ifs and menus.)

The DSP wall clock timer is a timer driven directly by
external oscillator and is external to the CPU core(s).
It is not as fast as the internal core clock, but provides
a common and synchronized counter for all CPU cores (which
is useful for SMP).
(The ‘depends on’ condition includes propagated dependencies from ifs and menus.)
