OK > Desktop box did, it gained a working ondemand, while its previously > working powersave went broke. Most likely that's because it was handled by intel_pstate in the "active" mode previously, while it is now handled by it in the "passive" mode (the modes are described in detail in Documentation/admin-guide/pm/intel_pstate.rst) and the default governor should be "schedutil". Which should be slightly better from the functionality perspective. > Box had schedutil forced upon it, but it > seems perfectly fine with that performance wise. Which is the expected outcome (sorry for the confusion). Cheers!
