This is necessary # to avoid a race condition while running ktrdump, i.e. the KTR ring buffer # will cycle a bit while ktrdump runs, and this confuses schedgraph because # the timestamps appear to go backwards at some point. Stopping KTR logging # while the workload is still running is to avoid wasting log entries on # "idle" time at the end. # - Dump the trace to a file: 'ktrdump -ct > ktr.out' # - Run the python script: 'python schedgraph.py ktr.out' optionally provide # your cpu frequency in ghz: 'python schedgraph.py ktr.out 2.4' # # To do: # Add a per-source summary display # "Vertical rule" to help relate data in
