Device drivers infrastructure | Linux 6.18.37

요약·해설, 영어 원문, 전체 번역을 구분해 실었습니다. API 이름, 코드 심벌, 소스 경로는 원문 표기를 유지합니다.

1. 요약·해설

원문의 핵심 내용을 정리하고 커널 프로그래밍에 필요한 설명을 덧붙였습니다. 아래의 전체 번역과는 별도로 작성한 해설입니다.

요약과 해설

infrastructure.rst:1-103

Driver infrastructure page는 device·bus·class·driver object 선언과 base implementation, DMA mapping, PnP, UIO API의 source map입니다. 같은 identifier가 여러 section에서 중복되지 않도록 kernel-doc include·exclude directive도 그대로 보존합니다.

2. 영어 원문 전체

번역에 사용한 Linux v6.18.37 원문입니다. 줄 번호는 해당 버전의 소스 파일을 기준으로 합니다.

영어 원문의 문단 순서와 의미에 맞춰 전체 내용을 번역했습니다. 코드, 함수명, 코드 심벌, URL은 원문 표기를 유지합니다.

기본 driver-model structure

1-19

문서 제목은 `Device drivers infrastructure`입니다. 기본 device driver-model structure section은 `device`, `bus_type`, `bus_notifier_event`, `class`, `probe_type`, `device_driver` 선언을 header별로 문서화합니다. `device_link_state`는 이 internal kernel-doc 범위에서 제외합니다.

.. kernel-doc:: include/linux/device.h
   :internal:
   :no-identifiers: device_link_state

.. kernel-doc:: include/linux/device/bus.h
   :identifiers: bus_type bus_notifier_event

Device Drivers Base

20-70

Device Drivers Base section은 base initialization, driver·core·syscore, class, faux device, NUMA node, transport class, device-driver binding, platform device와 bus implementation을 다룹니다.

Header kernel-doc을 다시 포함할 때 이미 기본 structure section에서 문서화한 `probe_type`, `device_driver`, `class`, `bus_type`, `bus_notifier_event`는 `:no-identifiers:`로 제외합니다. Source implementation은 internal 또는 exported 범위를 원문 directive대로 보존합니다.
