7.31. cpuspeed

Bug Fix

BZ#1196755, BZ#1211828, BZ#1219780, BZ#1225024

A previous update brought in a change in the kernel introducing the intel_pstate driver, incompatible with how scaling was managed until Red Hat Enterprise Linux 6.7. Consequently, the cpuspeed service printed needless error messages during system boot and shutdown. With this update, platforms using intel_pstate support only the "performance" and "powersave" scaling governors, the default option and default state being "powersave". If the user has set a different governor from the above-mentioned, for example "ondemand" or "conservative", they have to edit the configuration and choose one from the two, "powersave" or "performance". In addition, needless error messages are no longer returned.
