The loops_per_jiffy fixup looks like this: if (!(freq->flags & CPUFREQ_CONST_LOOPS)) cpu_data(freq->cpu).loops_per_jiffy = cpufreq_scale(loops_per_jiffy_ref, ref_freq, freq->new); i.e. X86_FEATURE_CONSTANT_TSC excluded. The sched_clock() scaling factor is modified like this: if (!(freq->flags & CPUFREQ_CONST_LOOPS)) { tsc_khz = cpu_khz; preempt_disable(); set_cyc2ns_scale(cpu_khz, smp_processor_id()); so here X86_FEATURE_CONSTANT_TSC is excluded again. So the whole frequency scaling issue will become a pure legacy issue only with time. Ingo --
