    The Intel(R) Speed select technologies contains four features.
    
    Performance profile:An non architectural mechanism that allows multiple
    optimized performance profiles per system via static and/or dynamic
    adjustment of core count, workload, Tjmax, and TDP, etc. aka ISS
    in the documentation.
    
    Base Frequency: Enables users to increase guaranteed base frequency on
    certain cores (high priority cores) in exchange for lower base frequency
    on remaining cores (low priority cores). aka PBF in the documenation.
    
    Turbo frequency: Enables the ability to set different turbo ratio limits
    to cores based on priority. aka FACT in the documentation.
    
    Core power: An Interface that allows user to define per core/tile
    priority.
    
    There is a multi level help for commands and options. This can be used
    to check required arguments for each feature and commands for the
    feature.
    
    To start navigating the features start with
    
    $sudo intel-speed-select --help
    
    For help on a specific feature for example
    $sudo intel-speed-select perf-profile --help
    
    To get help for a command for a feature for example
    $sudo intel-speed-select perf-profile get-lock-status --help
