H A 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, 144 Just as with dyntick-idle mode, the benefits of adaptive-tick mode do [all …]
