Add compact map display that does not output the whole cpu matrix, only cpus that got event. $ perf sched map --compact *A0 1082427.094098 secs A0 => perf:19404 (CPU 2) A0 *. 1082427.094127 secs . => swapper:0 (CPU 1) A0 . *B0 1082427.094174 secs B0 => rcuos/2:25 (CPU 3) A0 . *. 1082427.094177 secs *C0 . . 1082427.094187 secs C0 => migration/2:21 C0 *A0 . 1082427.094193 secs *. A0 . 1082427.094195 secs *D0 A0 . 1082427.094402 secs D0 => rngd:968 *. A0 . 1082427.094406 secs . *E0 . 1082427.095221 secs E0 => kworker/1:1:5333 . E0 *F0 1082427.095227 secs F0 => xterm:3342 It helps to display sane output for small thread loads on big cpu servers.
