hi all: usually I use cat /sys/kernel/debug/tracing/trace to look the ftrace result. Is it possible 1. direct trace to some file 2. enable ftrace 3. starting tracing what I interested 4. stop ftrace 5. open the file of #1 I directed that mean I can see whole trace log from #2 to #4 -- Regards, _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
