Rafael, honestly speaking I didn't like this patch very much. We need to fix a very specific problem with the intel-pstate driver when it is used with powersave/performance governor to make sure the hard limits are enforced. And this is something which no one else may face as well. What about doing something like this instead in the intel_pstate driver only to get this fixed ? if (!strcmp(policy->governor->name, "powersave") || !strcmp(policy->governor->name, "performance")) hard-limit-to-be-enforced; This would be a much simpler and contained approach IMHO. -- viresh
