Merge tag 'docs-6.6' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
"Documentation work keeps chugging along; this includes:
- Work from Carlos Bilbao to integrate rustdoc output into the
generated HTML documentation. This took some work to figure out how
to do it without slowing the docs build and without creating people
who don't have Rust installed, but Carlos got there
- Move the loongarch and mips architecture documentation under
Documentation/arch/
- Some more maintainer documentation from Jakub
... plus the usual assortment of updates, translations, and fixes"

It spreads the burden, helps +people take vacations and prevents burnout, trains new members of +the community etc. etc. Even when there is clearly one perfect candidate, +another maintainer should be found. + +Maintainers must be human, therefore, it is not acceptable to add a mailing +list or a group email as a maintainer.

Having a mailing list *in addition* to humans is perfectly fine. + +Corporate structures +-------------------- + +To an outsider the Linux kernel may resemble a hierarchical organization +with Linus as the CEO.

The EFI stub retrieves the boot hartid using +one of the following methods: + +- ``RISCV_EFI_BOOT_PROTOCOL`` (**preferred**). +- ``boot-hartid`` devicetree subnode (**deprecated**). + +Any new firmware must implement ``RISCV_EFI_BOOT_PROTOCOL`` as the devicetree +based approach is deprecated now. + +Early Boot Requirements and Constraints +======================================= + +The RISC-V kernel's early boot process operates under the following constraints: + +EFI stub and devicetree +----------------------- + +When booting with UEFI, the devicetree is supplemented (or created) by the EFI +stub with the same parameters as arm64 which are described at the paragraph +"UEFI kernel support on ARM" in Documentation/arch/arm/uefi.rst. + +Virtual mapping installation +---------------------------- + +The installation of the virtual mapping is done in 2 steps in the RISC-V kernel: + +1. ``setup_vm()`` installs a temporary kernel mapping in ``early_pg_dir`` which + allows discovery of the system memory. Only the kernel text/data are mapped + at this point. When establishing this mapping, no allocation can be done + (since the system memory is not known yet), so ``early_pg_dir`` page table is + statically allocated (using only one table for each level). + +2. ``setup_vm_final()`` creates the final kernel mapping in ``swapper_pg_dir`` + and takes advantage of the discovered system memory to create the linear + mapping. When establishing this mapping, the kernel can allocate memory but + cannot access it directly (since the direct mapping is not present yet), so + it uses temporary mappings in the fixmap region to be able to access the + newly allocated page table levels. + +For ``virt_to_phys()`` and ``phys_to_virt()`` to be able to correctly convert +direct mapping addresses to physical addresses, they need to know the start of +the DRAM. This happens after step 1, right before step 2 installs the direct +mapping (see ``setup_bootmem()`` function in arch/riscv/mm/init.c). Any usage of +those macros before the final virtual mapping is installed must be carefully +examined. + +Devicetree mapping via fixmap +----------------------------- + +As the ``reserved_mem`` array is initialized with virtual addresses established +by ``setup_vm()``, and used with the mapping established by +``setup_vm_final()``, the RISC-V kernel uses the fixmap region to map the +devicetree. This ensures that the devicetree remains accessible by both virtual +mappings. + +Pre-MMU execution +----------------- + +A few pieces of code need to run before even the first virtual mapping is +established. These are the installation of the first virtual mapping itself, +patching of early alternatives and the early parsing of the kernel command line. +That code must be very carefully compiled as: + +- ``-fno-pie``: This is needed for relocatable kernels which use ``-fPIE``, + since otherwise, any access to a global symbol would go through the GOT which + is only relocated virtually. +- ``-mcmodel=medany``: Any access to a global symbol must be PC-relative to + avoid any relocations to happen before the MMU is setup. +- *all* instrumentation must also be disabled (that includes KASAN, ftrace and + others). + +As using a symbol from a different compilation unit requires this unit to be +compiled with those flags, we advise, as much as possible, not to use external +symbols. diff --git a/Documentation/riscv/hwprobe.rst b/Documentation/riscv/hwprobe.rst index 933c715065d6..20eff9650da9 100644 --- a/Documentation/riscv/hwprobe.rst +++ b/Documentation/riscv/hwprobe.rst @@ -88,11 +88,11 @@ The following keys are defined: always extremely slow. * :c:macro:`RISCV_HWPROBE_MISALIGNED_SLOW`: Misaligned accesses are supported - in hardware, but are slower than the cooresponding aligned accesses + in hardware, but are slower than the corresponding aligned accesses sequences. * :c:macro:`RISCV_HWPROBE_MISALIGNED_FAST`: Misaligned accesses are supported - in hardware and are faster than the cooresponding aligned accesses + in hardware and are faster than the corresponding aligned accesses sequences. * :c:macro:`RISCV_HWPROBE_MISALIGNED_UNSUPPORTED`: Misaligned accesses are diff --git a/Documentation/riscv/index.rst b/Documentation/riscv/index.rst index 81cf6e616476..4dab0cb4b900 100644 --- a/Documentation/riscv/index.rst +++ b/Documentation/riscv/index.rst @@ -6,6 +6,7 @@ RISC-V architecture :maxdepth: 1 acpi + boot boot-image-header vm-layout hwprobe diff --git a/Documentation/riscv/vector.rst b/Documentation/riscv/vector.rst index 165b7ed0ac4f..75dd88a62e1d 100644 --- a/Documentation/riscv/vector.rst +++ b/Documentation/riscv/vector.rst @@ -13,7 +13,7 @@ order to support the use of the RISC-V Vector Extension.

Linux se +beneficia mucho de este tipo de investigación, y la mayoría de los +aspectos de Linux son impulsados por investigación en una forma u otra. + +La comunidad agradece mucho si los investigadores pueden compartir +los hallazgos preliminares antes de hacer públicos sus resultados, +especialmente si tal investigación involucra seguridad. Involucrarse +temprano ayuda a mejorar la calidad de investigación y la capacidad +de Linux para mejorar a partir de ella. En cualquier caso, se recomienda +compartir copias de acceso abierto de la investigación publicada con +la comunidad. + +Este documento busca clarificar lo que la comunidad del kernel de Linux +considera practicas aceptables y no aceptables al llevar a cabo +investigación de este tipo. Por lo menos, dicha investigación y +actividades afines deben seguir las reglas estándar de ética de la +investigación. Para más información sobre la ética de la investigación +en general, ética en la tecnología y la investigación de las comunidades +de desarrolladores en particular, ver: + + +* `Historia de la Ética en la Investigación <https://www.unlv.edu/research/ORI-HSR/history-ethics>`_ +* `Ética de la IEEE <https://www.ieee.org/about/ethics/index.html>`_ +* `Perspectivas de Desarrolladores e Investigadores sobre la Ética de los Experimentos en Proyectos de Código Abierto <https://arxiv.org/pdf/2112.13217.pdf>`_ + +La comunidad del kernel de Linux espera que todos los que interactúan con +el proyecto están participando en buena fe para mejorar Linux. La +investigación sobre cualquier artefacto disponible públicamente (incluido, +pero no limitado a código fuente) producido por la comunidad del kernel +de Linux es bienvenida, aunque la investigación sobre los desarrolladores +debe ser claramente opcional. + +La investigación pasiva que se basa completamente en fuentes disponibles +públicamente, incluidas las publicaciones en listas de correo públicas y +las contribuciones a los repositorios públicos, es claramente permitida. +Aunque, como con cualquier investigación, todavía se debe seguir la ética +estándar. + +La investigación activa sobre el comportamiento de los desarrolladores, +sin embargo, debe hacerse con el acuerdo explícito y la divulgación +completa a los desarrolladores individuales involucrados. No se puede +interactuar / experimentar con los desarrolladores sin consentimiento; +esto también es ética de investigación estándar. + +Para ayudar a aclarar: enviar parches a los desarrolladores es interactuar +con ellos, pero ya han dado su consentimiento para recibir contribuciones +en buena fe. No se ha dado consentimiento para enviar parches intencionalmente +defectuosos / vulnerables o contribuir con la información engañosa a las +discusiones. Dicha comunicación puede ser perjudicial al desarrollador (por +ejemplo, agotar el tiempo, el esfuerzo, y la moral) y perjudicial para el +proyecto al erosionar la confianza de toda la comunidad de desarrolladores en +el colaborador (y la organización del colaborador en conjunto), socavando +los esfuerzos para proporcionar reacciones constructivas a los colaboradores +y poniendo a los usuarios finales en riesgo de fallas de software. + +La participación en el desarrollo de Linux en sí mismo por parte de +investigadores, como con cualquiera, es bienvenida y alentada. La +investigación del código de Linux es una práctica común, especialmente +cuando se trata de desarrollar o ejecutar herramientas de análisis que +producen resultados procesables. + +Cuando se interactúa con la comunidad de desarrolladores, enviar un +parche ha sido tradicionalmente la mejor manera para hacer un impacto. +Linux ya tiene muchos errores conocidos – lo que es mucho más útil es +tener soluciones verificadas. Antes de contribuir, lea cuidadosamente +la documentación adecuada. + +* Documentation/process/development-process.rst +* Documentation/process/submitting-patches.rst +* Documentation/admin-guide/reporting-issues.rst +* Documentation/process/security-bugs.rst + +Entonces envíe un parche (incluyendo un registro de confirmación con +todos los detalles enumerados abajo) y haga un seguimiento de cualquier +comentario de otros desarrolladores. + +* ¿Cuál es el problema específico que se ha encontrado? +* ¿Como podría llegar al problema en un sistema en ejecución? +* ¿Qué efecto tendría encontrar el problema en el sistema? +* ¿Como se encontró el problema? Incluya específicamente detalles sobre + cualquier prueba, programas de análisis estáticos o dinámicos, y cualquier + otra herramienta o método utilizado para realizar el trabajo. +* ¿En qué versión de Linux se encontró el problema? Se prefiere usar la + versión más reciente o una rama reciente de linux-next (ver + Documentation/process/howto.rst). +* ¿Que se cambió para solucionar el problema y por qué se cree es correcto? +* ¿Como se probó el cambio para la complicación y el tiempo de ejecución? +* ¿Qué confirmación previa corrige este cambio? Esto debería ir en un “Fixes:” + etiqueta como se describe en la documentación. +* ¿Quién más ha revisado este parche? Esto debería ir con la adecuada “Reviewed-by” + etiqueta; Vea abajo. + +Por ejemplo (en inglés, pues es en las listas):: + + From: Author <author@email> + Subject: [PATCH] drivers/foo_bar: Add missing kfree() + + The error path in foo_bar driver does not correctly free the allocated + struct foo_bar_info. This can happen if the attached foo_bar device + rejects the initialization packets sent during foo_bar_probe(). This + would result in a 64 byte slab memory leak once per device attach, + wasting memory resources over time. + + This flaw was found using an experimental static analysis tool we are + developing, LeakMagic[1], which reported the following warning when + analyzing the v5.15 kernel release: + + path/to/foo_bar.c:187: missing kfree() call? + + Add the missing kfree() to the error path. No other references to + this memory exist outside the probe function, so this is the only + place it can be freed. + + x86_64 and arm64 defconfig builds with CONFIG_FOO_BAR=y using GCC + 11.2 show no new warnings, and LeakMagic no longer warns about this + code path. As we don't have a FooBar device to test with, no runtime + testing was able to be performed. + + [1] https://url/to/leakmagic/details + + Reported-by: Researcher <researcher@email> + Fixes: aaaabbbbccccdddd ("Introduce support for FooBar") + Signed-off-by: Author <author@email> + Reviewed-by: Reviewer <reviewer@email> + +Si usted es un colaborador por primera vez, se recomienda que el parche en +si sea examinado por otros en privado antes de ser publicado en listas +públicas. (Esto es necesario si se le ha dicho explícitamente que sus parches +necesitan una revisión interna más cuidadosa.) Se espera que estas personas +tengan su etiqueta “Reviewed-by” incluida en el parche resultante. Encontrar +otro desarrollador con conocimiento de las contribuciones a Linux, especialmente +dentro de su propia organización, y tener su ayuda con las revisiones antes de +enviarlas a las listas de correo publico tiende a mejorar significativamente la +calidad de los parches resultantes, y reduce así la carga de otros desarrolladores. + +Si no se puede encontrar a nadie para revisar internamente los parches y necesita +ayuda para encontrar a esa persona, o si tiene alguna otra pregunta relacionada +con este documento y las expectativas de la comunidad de desarrolladores, por +favor contacte con la lista de correo privada Technical Advisory Board: +<tech-board@lists.linux-foundation.org>. diff --git a/Documentation/translations/zh_CN/arch/index.rst b/Documentation/translations/zh_CN/arch/index.rst index 6fa0cb671009..e3d273d7d599 100644 --- a/Documentation/translations/zh_CN/arch/index.rst +++ b/Documentation/translations/zh_CN/arch/index.rst @@ -8,12 +8,12 @@ .. toctree:: :maxdepth: 2 - ../mips/index + mips/index arm64/index ../riscv/index openrisc/index parisc/index - ../loongarch/index + loongarch/index TODOList: diff --git a/Documentation/translations/zh_CN/loongarch/booting.rst b/Documentation/translations/zh_CN/arch/loongarch/booting.rst index fb6440c438f0..d2f55872904e 100644 --- a/Documentation/translations/zh_CN/loongarch/booting.rst +++ b/Documentation/translations/zh_CN/arch/loongarch/booting.rst @@ -1,8 +1,8 @@ ..
