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).
