perf tools: Resolve idle thread cmdline for perf trace
The cmd-trace tool used the cmdline file and resolved the idle thread using a hardcoded check for the 0 task pid. Now we have a centralized way to do that from perf using register_idle_thread() API. Before: :0-0 [000] 0.000000: irq_handler_entry: irq=0 handler=name :0-0 [000] 0.000000: irq_handler_entry: irq=0 handler=name After: [idle]-0 [000] 0.000000: irq_handler_entry: irq=0 handler=name [idle]-0 [000] 0.000000: irq_handler_entry: irq=0 handler=name Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> LKML-Reference: <1251693921-6579-2-git-send-email-fweisbec@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
