RT_PREEMPT 적용

Lubuntu 16.04 배포판에 RT_PREEMPT 패치가 포함된 커널을 설치하려고 하는데 어떻게 처리해야 할지 모르는 몇 가지 문제가 발생했습니다. 커널 v4.4.12(linux-4.4.12.tar.xz)의 소스 코드를 커널에서 다운로드했으며 적합하다고 생각되는 RT_PREEMPT 패치(patches-4.4.12-rt20.tar.xz)를 다운로드했습니다. 정리하다. 나는 tar xf, 'd를 사용하여 커널 소스를 cd디렉토리로 추출한 다음 패치를 적용하려고 했습니다 xzcat ../patches-4.4.12.tar.xz | patch -p1(여기에 제안된 대로:https://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO). 이 명령은 존재하지 않는 파일에 대한 패치, 이전에 적용된 패치, 실패한 패치 등에 대해 불평하는 많은 오류를 생성합니다. 일부 패치 블록은 성공하는 것처럼 보였지만 많은 패치 블록이 실패했습니다.

이것은 이 커널을 패치하는 올바른 방법이 될 수 없습니다. 그렇죠? 내가 어디로 잘못 가고 있는지 아시나요?

편집: 다음은 내가 보고 있는 오류 유형을 다루는 예입니다.

|Subject: [PATCH 026/351] hwlat-detector: Use trace_clock_local if available
|
|As ktime_get() calls into the timing code which does a read_seq(), it
|may be affected by other CPUS that touch that lock. To remove this
|dependency, use the trace_clock_local() which is already exported
|for module use. If CONFIG_TRACING is enabled, use that as the clock,
|otherwise use ktime_get().
