116 The perf profiles programs with different modes: default mode, per thread
129 This command doesn't specify any options for CPU and thread modes, the
142 than for all threads in the system.  The *T1* thread represents the
143 thread context of the 'test_program', whereas *T2* and *T3* are irrelevant

146 which the *T1* thread is running.

195 2.2.2 Per-thread mode
198 By specifying option ``--per-thread`` in perf command, e.g.
202         perf record --per-thread test_program
211 In this mode, a single ring buffer is allocated for the profiled thread;
212 if the thread is scheduled on a CPU, the events on that CPU will be
213 enabled; and if the thread is scheduled out from the CPU, the events on
214 the CPU will be disabled.  When the thread is migrated from one CPU to

248                 Figure 4. Ring buffer for per-thread mode
250 When perf runs in per-thread mode, a ring buffer is allocated for the
251 profiled thread *T1*.  The ring buffer is dedicated for thread *T1*, if the
252 thread *T1* is running, the perf events will be recorded into the ring
253 buffer; when the thread is sleeping, all associated events will be
275 options for per-thread mode and per-CPU mode, e.g. the options ``–C 0,2`` and
276 ``––per–thread`` are specified together, the samples are recorded only when
277 the profiled thread is scheduled on any of the listed CPUs.
