stretch -> buster -> bullseye 로 배포판 명칭이 변경되면서 buster는 oldstable로 변경된 듯.

라즈베리 파이의 비디오 가속 하드웨어인 VideoCore 4를 openCL로 쓸 수 있도록 래핑한 프레임워크?
아무튼 라즈베리 1~3가 vc4 를 채용하고 있으니 의외로 범용성은 넓어 보이는데
성능이 얼마나 나올런지?
라즈베리파이 1-3 videocore iv 채용
라즈베리파이 4 videocore vi 채용

라즈베리의 config.txt는 uboot 와는 독립된 문법의 느낌이라면
odroid c2의 boot.ini 는 uboot의 환경설정 문법을 그대로 따라가는 느낌
그나저나 발열 문제 때문인가 클럭을 낮게 잡아놨네?
