| |
Depending on what is being done, the intel_pstate_tracer.py script needs to be run as root, or can be run as a regular user. If run the first time as root the results directory will be incorrect for any subsequent run as a regular user. For any run as root the specific testname subdirectory will not allow any subsequent file saves by a regular user. Typically, and for example, the regular user might be attempting to save a .csv file converted to a spreadsheet with added calculations or graphs.
Override the default folder permissions.
