1. include MTK scheduler enhancement.

2. All MTK scheduler sub-feature config should depend on

this config.

Original Linux Design, RT & CFS do load balance seperatedly,
|
||
|
|
and let would result in unload balance.
|
||
|
|
that is, one CPU has more than 2 tasks, however, one CPU is IDLE
|
||
|
|
We make RT & CFS to check each other and make load more balance.

Migrate misfit task more efficient in scheduler tick.
|

|
|
1. Big task migration: migrate misfit task in scheduler tick
|
||
|
|
To reduce boosted task push to big core latency.
|
||
|
|
Migrate current task to big core if it is misfit.
|
||
|
|
2. Big task rotation: swap two misfit task between big cores and
|
||
|
|
little core, equally distributed runtime for each misfit task.
