perf report: Show random usage tip on the help line
Currently perf report only shows a help message "For a higher level overview, try: perf report --sort comm,dso" unconditionally (even if the sort keys were used). Add more help tips and show randomly. Load tips from ${prefix}/share/doc/perf-tip/tips.txt file. $ perf report | tail 0.10% swapper [kernel.vmlinux] [k] irq_exit 0.09% swapper [kernel.vmlinux] [k] flush_smp_call_function_queue 0.08% swapper [kernel.vmlinux] [k] native_write_msr_safe 0.03% swapper [kernel.vmlinux] [k] group_sched_in 0.01% perf [kernel.vmlinux] [k] native_write_msr_safe # # (Tip: Search options using a keyword: perf report -h <keyword>) # Signed-off-by: Namhyung Kim <> Acked-by: Ingo Molnar <> Cc: Andi Kleen <> Cc: David Ahern <> Cc: Jiri Olsa <> Cc: Masami Hiramatsu <> Cc: Peter Zijlstra <> Cc: Stephane Eranian <> Cc: Wang Nan <> Link: [ Renamed it to perf_tip() and the parameter dirname to dirpath to fix the build on older distros ] Signed-off-by: Arnaldo Carvalho de Melo <>
