[PATCH] cpufreq: intel_pstate: Update Balance performance EPP for Granite Rapids

Posted by Srinivas Pandruvada 1 week, 3 days ago

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.

This is in line with what has already been done for Emerald Rapids and
Sapphire Rapids.
