To use dynamic sort keys, it might be good to add an option to see the
list of field names.
$ perf evlist -i perf.data.sched
sched:sched_switch
sched:sched_stat_wait
sched:sched_stat_sleep
sched:sched_stat_iowait
sched:sched_stat_runtime
sched:sched_process_fork
sched:sched_wakeup
sched:sched_wakeup_new
sched:sched_migrate_task
# Tip: use 'perf evlist --trace-fields' to show fields for tracepoint events
$ perf evlist -i perf.data.sched --trace-fields
sched:sched_switch: trace_fields: prev_comm,prev_pid,prev_prio,prev_state,next_comm,next_pid,next_prio
sched:sched_stat_wait: trace_fields: comm,pid,delay
sched:sched_stat_sleep: trace_fields: comm,pid,delay
sched:sched_stat_iowait: trace_fields: comm,pid,delay
sched:sched_stat_runtime: trace_fields: comm,pid,runtime,vruntime
sched:sched_process_fork: trace_fields: parent_comm,parent_pid,child_comm,child_pid
sched:sched_wakeup: trace_fields: comm,pid,prio,success,target_cpu
sched:sched_wakeup_new: trace_fields: comm,pid,prio,success,target_cpu
sched:sched_migrate_task: trace_fields: comm,pid,prio,orig_cpu,dest_cpu
Committer notes:
For another file, in verbose mode:
# perf evlist -v --trace-fields
sched:sched_switch: type: 2, size: 112, config: 0x10b, { sample_period, sample_freq }: 1, sample_type: IP|TID|TIME|CPU|PERIOD|RAW, disabled: 1, inherit: 1, mmap: 1, comm: 1, task: 1, sample_id_all: 1, exclude_guest: 1, mmap2: 1, comm_exec: 1, trace_fields: prev_comm,prev_pid,prev_prio,prev_state,next_comm,next_pid,next_prio

[ Replaced 'trace_fields=' with 'trace_fields: ' to make the output consistent in -v mode ]
