commit 18d9b5227121 ("cpufreq/amd-pstate: Use nominal perf for limits when boost is disabled") introduced different semantics for min/max limits based upon whether the user turned off boost from sysfs. This however is not necessary when the highest perf value is the boost numerator. Suggested-by: Dhananjay Ugwekar <Dhananjay.Ugwekar@amd.com> Reviewed-by: Gautham R.
