119 By default, no CPU will be an adaptive-ticks CPU. The "nohz_full="
120 boot parameter specifies the adaptive-ticks CPUs. For example,
121 "nohz_full=1,6-8" says that CPUs 1, 6, 7, and 8 are to be adaptive-ticks

Dhighres.txt1 High resolution timers and dynamic ticks design notes
26 - dynamic ticks
39 - independent of ticks (the processing is based on nanoseconds)
52 convert the clock ticks to nanosecond based time values. All other time keeping
79 functionality like high resolution timers or dynamic ticks.
130 enabling of high resolution timers and dynamic ticks is simply provided by
159 dynamic ticks on i386 SMP systems which stop the local APIC in C3 power
204 dynamic ticks
207 Dynamic ticks are the logical consequence of the hrtimer based periodic tick
