TESTS

$ ./tests/run-tests.sh

USAGE

$ perf_script_processor -p <dir path> -t <test type>

Example: $ perf_script_processor -p . -t 0

-p (defaults to /tmp/pp_results) is where one of the following exists:

  • perf.data -- binary file. If you're running this tool on perf.data, make sure you're running it from the system where the binary was generated
  • raw_perf -- plain text output when perf script is run on folder containing perf.data
  • perf_data.csv -- generated in the process of generating results

-t (defaults to 0) is either 0 or 1. It's the type of test that generated perf.data.

  • 0: Native
  • 1: Threads

NOTE: The stats at the end of run, will be stored in delta_output.log in folder where you've generate the output.
