We already were able to ask for callchains for a specific event:
# trace -e nanosleep --call dwarf --event sched:sched_switch/call-graph=fp/ usleep 1
This would enable tracing just the "nanosleep" syscall, with callchains
at syscall exit and would ask the kernel for frame pointer callchains to
be enabled for the "sched:sched_switch" tracepoint event, its just that
we were not resolving the callchain and printing it in 'perf trace', do
it:
# trace -e nanosleep --call dwarf --event sched:sched_switch/call-graph=fp/ usleep 1
0.425 ( 0.013 ms): usleep/6718 nanosleep(rqtp: 0x7ffcc1d16e20) ...

#
Pretty compact, huh? DWARF callchains for raw_syscalls:sys_exit + frame
pointer callchains for a tracepoint, if your hardware supports LBR, go
wild with /call-graph=lbr/, guess the next step is to lift this from
'perf script':
-F, --fields <str> comma separated output fields prepend with 'type:'. Valid types: hw,sw,trace,raw.
Fields: comm,tid,pid,time,cpu,event,trace,ip,sym,dso,addr,symoff,period,iregs,brstack,brstacksym,flags

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.
