When BIOS disables turbo, the cpuinfo_max_freq will also be same as the power up base frequency. When SST-PP causes increase in base frequency the performance will be still limited to the old base frequency as the cpuinfo_max_freq will not be updated. In this case we need to update scaling_max frequency to the new base_frequency. This will result in setting updated max performance limit in the Pstate driver. So performance will not be limited to the old base frequency.
