quickly for them as search for best match is faster.



By calling cpufreq_table_validate_and_show(), the cpuinfo.min_freq and

cpuinfo.max_freq values are detected, and policy->min and policy->max

are set to the same values. This is helpful for the per-CPU

initialization stage.

The cpufreq table is verified automatically by the core if the policy contains a

valid pointer in its policy->freq_table field.



cpufreq_frequency_table_verify() assures that at least one valid

frequency is within policy->min and policy->max, and all other criteria
