I am trying to run systrace on a non-rooted device. It always gives the following error if any of the trace events is selected:
Unable to find trace start marker 'TRACE:': error opening /sys/kernel/debug/tracing/events/cpufreq_interactive/enable: No such file or directory
If no trace event is selected, it works, but the trace is not very usweful.
Does systrace requires root access?
Note that I am running systrace directly from Eclipse (DDMS) on Windows-7.
