non-linear DVFS control
|
|
EAS enhancement

Choose this option to provide per-opp capacity API.
|
|
Scheduler module will get per-opp capacity from sram and
|
|
initialize opp capacity table. This config is used by
|
|
performance tuning framework and non-linear frequency control.

help
|

Choose this option to enable non-linear frequency control.
|
|
This will change per-opp capacity from linear scaled by
|
|
freuqency to evaluated by benchmark. This makes capacity
|
|
more accurate and will let scheduler/schedutil use more
|
|
suitable frequency.

MTK EAS enhancement features.
|
|
These featues include
|
|
1. load balance in the same frequency domain
|
|
2. hint aware in idle balance
|
|
3. Notify thermal ceiling to scheduler by reading thermal
|
|
ceiling in SRAM and updating thermal pressure.
