mainline:240a8da623008eb9f4e32c7a19ce16a6605911dc severity: Moderate upstream commit 240a8da ("cpufreq: intel_pstate: Allow model specific EPPs") The current implementation allows model specific EPP override for balanced_performance. Add feature to allow model specific EPP for all predefined EPP strings. For example for some CPU models, even changing performance EPP has benefits Use a mask of EPPs as driver_data instead of just balanced_performance.

mainline:1f4b7fdd71e066aa7c01e3e26ceeb39b47dd5461 severity: Moderate upstream commit 1f4b7fd ("cpufreq: intel_pstate: Update default EPPs for Meteor Lake") Update default balanced_performance EPP to 115 and performance EPP to 16. Changing the balanced_performance EPP has better performance/watt compared to default powerup EPP value of 128. Changing the performance EPP to 0x10 shows reduced power for similar performance as EPP 0. On small form factor devices this is beneficial as lower power results in lower CPU and skin temperature. This results in reduced thermal throttling and higher performance.
