The injection of a fake cpu_frequency event in the trace may end up getting interleaved with trace events generated by the cpufreq governor, for example: sh ... cpu_frequency: state=120000 cpu_id=0 kschedfreq ... cpu_frequency: state=120000 cpu_id=0 kschedfreq ... cpu_frequency: state=120000 cpu_id=1 kschedfreq ... cpu_frequency: state=120000 cpu_id=2 kschedfreq ... cpu_frequency: state=120000 cpu_id=3 sh ... cpu_frequency: state=120000 cpu_id=1 sh ... cpu_frequency: state=120000 cpu_id=2 sh ... cpu_frequency: state=120000 cpu_id=3 Such a trace may confuse trace parsers during postprocessing and lead to wrong or no results. This patch renames the events injected by devlib so that they can be easily recognized and then used by the trace parser in the best way. Signed-off-by: Michele Di Giorgio <michele.digiorgio@arm.com>
