68 This file has one line per CPU, or eight for this 8-CPU system.
71 o The number at the beginning of each line is the CPU number.
78 o "c" is the count of grace periods that this CPU believes have
80 quite a ways behind, for example, CPU 4 under "rcu_sched" above,
87 o "g" is the count of grace periods that this CPU believes have
89 may lag behind. If the "c" and "g" values are equal, this CPU
91 period that it is aware of, otherwise, the CPU believes that it
94 o "pq" indicates that this CPU has passed through a quiescent state
97 the CPU has passed through a quiescent state, either (1) this
98 CPU has not yet reported that fact, (2) some other CPU has not
102 this CPU. Offlined CPUs and CPUs in dyntick idle mode might
107 due to an interrupt. This number is even if the CPU is in idle
117 o "df" is the number of times that some other CPU has forced a
118 quiescent state on behalf of this CPU due to this CPU being in
121 o "of" is the number of times that some other CPU has forced a
122 quiescent state on behalf of this CPU due to this CPU being

132 this CPU. The first number is the number of "lazy" callbacks
166 o "b" is the batch limit for this CPU. If more than this number

172 been registered in absence of CPU-hotplug activity.
175 this CPU. This will always be zero unless the kernel was built
180 this CPU going offline. These orphaned callbacks have been moved
181 to an arbitrarily chosen online CPU.
184 CPU due to other CPUs going offline. Note that ci+co-ca+ql is
185 the number of RCU callbacks registered on this CPU.
203 o "kt" is the per-CPU kernel-thread state. The digit preceding
218 forced off of its designated CPU or because its

222 "Y" The kernel thread is yielding to avoid hogging CPU.
226 The number after the final slash is the CPU that the kthread
232 the number of times that this CPU's per-CPU kthread has gone
252 o "n" is number of times that a concurrent CPU-hotplug operation
269 CPU whose "c" field matches the value of "completed" is aware
274 a CPU whose "g" field matches the value of "gpnum" is aware that
308 other CPU via force_quiescent_state().
394 o The leading number is the CPU number, with "!" indicating
395 an offline CPU.
401 quiescent state from this CPU.
403 o "rpq" is the number of times that the CPU had passed through
406 o "cbr" is the number of times that this CPU had RCU callbacks
410 o "cng" is the number of times that this CPU needed another
414 completed, but this CPU was not yet aware of it.
417 but this CPU was not yet aware of it.
423 o "nn" is the number of times that this CPU needed nothing.
436 o "n:m" is the CPU-number range for the corresponding two-line
474 "Y" The kernel thread is yielding to avoid hogging CPU.
