부팅 속도 최적화라는 공부를 시작한지 어느덧 3일이 지났다.
리눅스 커널과 init에 대한 아주 얄팍한 지식으로 무식하게 진행하고 있으나, 좌충우돌하면서 하나하나 배우는 재미가 쏠쏠하다.
초단위로 적당히 단축을 하다가 어느던 ~100msec 단위에서 최적화를 보고 있다.
다시 힘차게 4일차 아침을 시작해 보자. 오늘도 시간과의 싸움이다.
비교적 간단한 커널관련 작업으로 부팅시간이 많이 줄었으나, 아직 해볼만한 것들이 남아있는지 프로파일링을 해보자.
커널 설정은 변경없이 bootcmd만 수정하여 bootargs에 "initcall_debug printk.time=1"만 추가하였다.
보드를 부팅하고 command line에서 dmesg > kernel.log로 커널 메시지를 저장하였다.
커널 로그 파일은 아래와 같이 initcall 호출하는 부분이 일일이 타임스탬프로 찍혀있어 매우 방대하다.

그리고 리눅스 소스코드에 포함된 bootgraph라는 펄-스크립트를 이용하여 svg 포맷의 그래프를 생성하였다.
./linux/scripts/bootgraph.pl kernel.log > boot.svg아래는 생성된 파일을 PNG로 변경한 것이다.
그래프의 글씨가 잘 안 보인다. SVG 뷰어로 확대해서 분석하는 것이 더 편리하다. 참고를 위해 svg 원본을 첨부한다.
시간이 긴것부터 몇 개만 살펴보자.
마지막 700ms 이후는 장치들 probe 과정이므로 단축이 쉽지는 않을것 같다.
350 ~ 600ms 구간의 I2C 버스에 연결된 터치스크린과 카메라의 초기화 시간이 가장 길었다. 역시나 I2C 버스는 너무 느리다.
I2C에 연결된 드라이버는 모듈로 변경하면 300ms 정도 단축이 가능해 보이나, 어플리케이션이 구동될때 모듈 로딩이 필요하므로 조삼모사가 될 가능성이 크다.
USB 호스트용 EHCI/OHCI 드라이버는 200ms 정도 소요되고 있으나 범용이므로 건드리지 말자.
DW8250이라는 UART 드라이버 초기화도
이더넷과 사운드 드라이버에 필요한 시간은 상대적으로 미미해 보인다.
커널의 부팅 시간 분석은 이 정도에서 마무리하고 u-boo 최신 버전을 포팅하여 테스트를 해보았다.

부팅이 완료되는데 3.5초 미만의 시간이 소요되었다. 3.81초에서 3.36초로 400ms 이상 줄어들었다.
SPL 시작에서 Starting Kernel이 나올때까지 1.36초에서 1.07초로 줄어든 부분이 가장 큰것 같다.
falcon boot를 구현하면 2.5초 정도에 가능할것 같다.
그런데 계속 부트로더 개발에 시간을 투자한다는 것이 많이 아깝다고 생각한다.
최초 목표 4초를 초과 달성했으니 이 정도에서 마무리하겠다. 처음에 10여초가 넘었는데 60% 정도 단축시킨 것으로 판단한다.
참고로 Mainline u-boot은 안정성 떨어져서 DRAM 클럭을 살짝 낮추고 ZQ값 싸이클 숫자를 올려야만 안정적인 동작이 가능했다.
CPU의 DRAM controller 초기화 부분에 버그가 좀 있는것으로 보인다.
또한 LCD 지원 부분도 빠져있어, 당분간 구형 uboot을 사용할 것이다.
