It doesn't change the default scheduler classes. We'll still get CFS be default with the option to do RT and Deadline as before. I don't think RHEL currently deals with assymetric CPU capacity yet. But that may change. I wanted to get it enabled for ELN so that if/when we do need it it will be there w/o potential kABI issues. Primarily, there is interest in making the schedutil frequency governor the default and this relies on having the eneregy model built. Right now we use the performance governor in RHEL but if schedutil gets to where it provides the same performance while still being able to reduce power when less busy then that could change. Just enabling this config should not change that.
