1991년 8월 26일..

필란드의 젊은 대학생이 Unix/Minix 기반의 자작 OS를 발표하였습니다.

바로 리누즈 토발즈의 리눅스 입니다.

저는 그때 이등병으로 군생활을 시작한지 얼마 안되었을때이고,

한참 뒤 93년 말 병장 말년 휴가나와서 플로피디스크로 부팅 한번 시켜보았습니다. ㅎㅎㅎ

그런데 오늘 아침 22번째 Linux 생일 축하 메시지와 함께 리누즈께서 Kernel 3.11 RC7을 릴리즈 하셨습니다.

구글 플러스에 직접 올린 축하 메시지는 요기 링크를 보세요.

https://plus.google.com/+Linux/posts/f96weYxzEu1

Exynos-5410(ODROID-XU) 용으로 작업해 오던 3.11 커널에 패치를 때리고 우분투 부팅에 성공하였습니다.

USB, PLL, PMIC, DVFS, DRAM, eMMC-4.5, Ethernet  등등 기본적인 드라이버들은 DeviceTree 기반으로 구현이 되었습니다.

소스 코드는 아래 링크에서 다운로드 가능합니다.
