Since commit 77271ce4b2c0 ("tracing: Add irq, preempt-count and need resched info to default trace output"), the default trace output format has been changed to: -0 [009] d.h. 22420.068695: _raw_spin_lock_irqsave <-hrtimer_interrupt -0 [000] ..s. 22420.068695: _nohz_idle_balance <-run_rebalance_domains -0 [011] d.h. 22420.068695: account_process_tick <-update_process_times origin trace output format:(before v3.2.0) # tracer: nop # # TASK-PID CPU# TIMESTAMP FUNCTION # | | | | | migration/0-6 [000] 50.025810: rcu_note_context_switch <-__schedule migration/0-6 [000] 50.025812: trace_rcu_utilization <-rcu_note_context_switch migration/0-6 [000] 50.025813: rcu_sched_qs <-rcu_note_context_switch migration/0-6 [000] 50.025815: rcu_preempt_qs <-rcu_note_context_switch migration/0-6 [000] 50.025817: trace_rcu_utilization <-rcu_note_context_switch migration/0-6 [000] 50.025818: debug_lockdep_rcu_enabled <-__schedule migration/0-6 [000] 50.025820: debug_lockdep_rcu_enabled <-__schedule The draw_functrace.py(introduced in v2.6.28) can't parse the new version format trace_func, So we need modify draw_functrace.py to adapt the new version trace output format.
