xezr4oyit의 백업용 테이프들

max_arm_volt를 800 MHz의 물건을 주었지만 기동때에 1 GHz로 돌아 낮은 전압으로 적용 받는지 기동이 상당히 늦어 기동 후의 WiMAX tcp 버퍼 설정 스크립트에 넣어 보았다.

기동 하고 나서도 customvoltage의 영향을 받아 파라메타를 더 낮추면 반응이 늦어진다든가 하는 현상이 있고,

[지금의 max_int_volt는 한계? 같고 1120을 주면 스크롤이 늦어진다든가 하는 현상이 발생한다]

작동하고 있는 것을 확인할 수 있지만 좀 더 손을 대어 보는 것이 좋을지도
- 참고로 AOSP기반 롬의 CPU 설정의 // Set on boot // 부분은 체크해제한 후에 적용할 수 있도록..
