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.
