Public bug reported:
[ Impact ]
* Update EPP default for balance_performance to 32. This will give
better performance out of box using Intel P-State powersave governor
while still offering power savings compared to performance governor.
* Improvement of ~10% on perf per/watt.
[ Fix ]
* Clean cherry-pick from upstream:
00e2c199cb378 cpufreq: intel_pstate: Update Balance-performance EPP for
Granite Rapids
[ Test Plan ]
* Compiled and tested by intel.
[ Where problems could occur ]
* Performance or powersaving regression.
