79 bool "Idle dynticks system (tickless idle)"
83 This option enables a tickless idle system: timer interrupts
84 will only trigger on an as-needed basis when the system is idle.
132 bool "Detect full-system idle state for full dynticks system"
137 timekeeping purposes whenever there is a non-idle CPU, where
138 "non-idle" also includes dynticks CPUs as long as they are
139 running non-idle tasks. Because the underlying adaptive-tick
140 support cannot distinguish between all CPUs being idle and
144 are idle. This Kconfig option enables scalable detection of
145 the all-CPUs-idle state, thus allowing the scheduling-clock
146 tick to be disabled when all CPUs are idle. Note that scalable
147 detection of the all-CPUs-idle state means that larger systems
148 will be slower to declare the all-CPUs-idle state.
150 Say Y if you would like to help debug all-CPUs-idle detection.
160 The full-system idle detection mechanism takes a lazy approach
185 This is the old config entry that enables dynticks idle.
