| D | no_hz.rst | 114 and such CPUs are said to be "adaptive-ticks CPUs". This is important
124 By default, no CPU will be an adaptive-ticks CPU. The "nohz_full="
125 boot parameter specifies the adaptive-ticks CPUs. For example,
126 "nohz_full=1,6-8" says that CPUs 1, 6, 7, and 8 are to be adaptive-ticks
128 adaptive-tick CPUs: At least one non-adaptive-tick CPU must remain
130 calls like gettimeofday() returns accurate values on adaptive-tick CPUs.
136 Finally, adaptive-ticks CPUs must have their RCU callbacks offloaded.
139 Normally, a CPU remains in adaptive-ticks mode as long as possible.
141 the mode. Instead, the CPU will exit adaptive-ticks mode only if needed,
