@ -259,10 +259,8 @@ CPUFREQ_ENTRY_INVALID. The entries don't need to be in sorted in any
particular order, but if they are cpufreq core will do DVFS a bit
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
