Hi
These are some changes I have accumulated in the last weeks. Mostly improving the tool's user experience.
- On timerlat top, remove an extra \n that was breaking the output.
- Replace \t with ' ' on the auto analysis, fixing some copy & paste.
- On timerlat top, do not print TTY formatting characters when the output is not sent to a terminal, because they break the output.
- on timerlat top and hist, add a summary with the overall results. For instance, the minimum value for all CPUs, the overall average and the maximum value from all CPUs.
- Add a --warm-up <seconds> option, allowing the workload to run for <seconds> before starting to collect results.
- Add a --trace-buffer-size option, allowing the user to set the tracing buffer size. This is mainly useful for reducing the trace file.
- Make the user-space threads the default choice, also adding the a -k option, allowing the user to switch to kerne-threads.
