	This prints a textual context-switching outline of workload captured via perf sched record. For example, on a 16 CPU box it outputs: N1 O1 . . . S1 . . . B0 . I0 C1 . M1 . 23002.773423 secs N1 O1 . Q0 . S1 . . . B0 . I0 C1 . M1 . 23002.773423 secs N1 O1 . Q0 . S1 . . . B0 . R1 C1 . M1 . 23002.773485 secs N1 O1 . Q0 . S1 . S0 . B0 . R1 C1 . M1 . 23002.773478 secs L0 O1 . Q0 . S1 . S0 . B0 .

R1 C1 T1 M1 . 23002.773747 secs Columns stand for individual CPUs, from CPU0 to CPU15, and the two-letter shortcuts stand for tasks that are running on a CPU. '' denotes the CPU that had the event. A dot signals an idle CPU. New tasks are assigned new two-letter shortcuts - when they occur first they are printed. In the above example 'T1' stood for irqbalance: T1 => irqbalance:2089 Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> LKML-Reference: <new-submission> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-09-13	perf sched: Clean up PID sorting logic	Ingo Molnar
	Use a sort list for thread atoms insertion as well - instead of hardcoded for PID.

2009-08-15	perf tools: Factorize the thread code in a dedicated file	Frederic Weisbecker
	Factorize the thread management code used by perf-annotate and perf-report in dedicated source and header files. v2: pass last_match by address so that it can actually be modified.
