From 77f969a717b953296c036004b1a96f9d1087cef6 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Thu, 13 Jul 2023 16:07:13 -0700 Subject: [PATCH 01/56] MAINTAINERS: treat Documentation/maintainer as process docs A handful of people got caught out by the recent changes in git which changed the format of Message-ID and broke our recommended applyhook for adding lore links. This was fixed in the docs by commit 2bb19e740e9b ("Documentation: update git configuration for Link: tag") but it seems like few people have noticed. Add maintainer directory to the process entry so that workflows@ gets CCed.

SPDX-License-Identifier: GPL-2.0 + +============================== +Feature and driver maintainers +============================== + +The term "maintainer" spans a very wide range of levels of engagement +from people handling patches and pull requests as almost a full time job +to people responsible for a small feature or a driver. + +Unlike most of the chapter, this section is meant for the latter (more +populous) group. It provides tips and describes the expectations and +responsibilities of maintainers of a small(ish) section of the code. + +Drivers and alike most often do not have their own mailing lists and +git trees but instead send and review patches on the list of a larger +subsystem. + +Responsibilities +================ + +The amount of maintenance work is usually proportional to the size +and popularity of the code base. Small features and drivers should +require relatively small amount of care and feeding. Nonetheless +when the work does arrive (in form of patches which need review, +user bug reports etc.) it has to be acted upon promptly. +Even when a particular driver only sees one patch a month, or a quarter, +a subsystem could well have a hundred such drivers. Subsystem +maintainers cannot afford to wait a long time to hear from reviewers. + +The exact expectations on the response time will vary by subsystem. +The patch review SLA the subsystem had set for itself can sometimes +be found in the subsystem documentation. Failing that as a rule of thumb +reviewers should try to respond quicker than what is the usual patch +review delay of the subsystem maintainer. The resulting expectations +may range from two working days for fast-paced subsystems (e.g. networking) +to as long as a few weeks in slower moving parts of the kernel. + +Mailing list participation +-------------------------- + +Linux kernel uses mailing lists as the primary form of communication. +Maintainers must be subscribed and follow the appropriate subsystem-wide +mailing list. Either by subscribing to the whole list or using more +modern, selective setup like +`lei `_. + +Maintainers must know how to communicate on the list (plain text, no invasive +legal footers, no top posting, etc.) + +Reviews +------- + +Maintainers must review *all* patches touching exclusively their drivers, +no matter how trivial. If the patch is a tree wide change and modifies +multiple drivers - whether to provide a review is left to the maintainer. + +When there are multiple maintainers for a piece of code an ``Acked-by`` +or ``Reviewed-by`` tag (or review comments) from a single maintainer is +enough to satisfy this requirement. + +If the review process or validation for a particular change will take longer +than the expected review timeline for the subsystem, maintainer should +reply to the submission indicating that the work is being done, and when +to expect full results. + +Refactoring and core changes +---------------------------- + +Occasionally core code needs to be changed to improve the maintainability +of the kernel as a whole. Maintainers are expected to be present and +help guide and test changes to their code to fit the new infrastructure. + +Bug reports +----------- + +Maintainers must ensure severe problems in their code reported to them +are resolved in a timely manner: regressions, kernel crashes, kernel warnings, +compilation errors, lockups, data loss, and other bugs of similar scope. + +Maintainers furthermore should respond to reports about other kinds of +bugs as well, if the report is of reasonable quality or indicates a +problem that might be severe -- especially if they have *Supported* +status of the codebase in the MAINTAINERS file. + +Selecting the maintainer +======================== + +The previous section described the expectations of the maintainer, +this section provides guidance on selecting one and describes common +misconceptions. + +The author +---------- + +Most natural and common choice of a maintainer is the author of the code. +The author is intimately familiar with the code, so it is the best person +to take care of it on an ongoing basis. + +That said, being a maintainer is an active role. The MAINTAINERS file +is not a list of credits (in fact a separate CREDITS file exists), +it is a list of those who will actively help with the code. +If the author does not have the time, interest or ability to maintain +the code, a different maintainer must be selected. + +Multiple maintainers +-------------------- + +Modern best practices dictate that there should be at least two maintainers +for any piece of code, no matter how trivial. 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. Trust and understanding are the +foundation of kernel maintenance and one cannot build trust with a mailing +list. 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. While the code flows in a hierarchical fashion, +the corporate template does not apply here. Linux is an anarchy held +together by (rarely expressed) mutual respect, trust and convenience. + +All that is to say that managers almost never make good maintainers. +The maintainer position more closely matches an on-call rotation +than a position of power. + +The following characteristics of a person selected as a maintainer +are clear red flags: + + - unknown to the community, never sent an email to the list before + - did not author any of the code + - (when development is contracted) works for a company which paid + for the development rather than the company which did the work + +Non compliance +============== + +Subsystem maintainers may remove inactive maintainers from the MAINTAINERS +file. If the maintainer was a significant author or played an important +role in the development of the code, they should be moved to the CREDITS file. + +Removing an inactive maintainer should not be seen as a punitive action. +Having an inactive maintainer has a real cost as all developers have +to remember to include the maintainers in discussions and subsystem +maintainers spend brain power figuring out how to solicit feedback. + +Subsystem maintainers may remove code for lacking maintenance. + +Subsystem maintainers may refuse accepting code from companies +which repeatedly neglected their maintainership duties. diff --git a/Documentation/maintainer/index.rst b/Documentation/maintainer/index.rst index 3e03283c144e..eeee27f8b18c 100644 --- a/Documentation/maintainer/index.rst +++ b/Documentation/maintainer/index.rst @@ -9,6 +9,7 @@ additions to this manual. .. toctree:: :maxdepth: 2 + feature-and-driver-maintainers configure-git rebasing-and-merging pull-requests From 1e6f64c53c8be1c7d3565945f9c5da0454bbc741 Mon Sep 17 00:00:00 2001 From: Avadhut Naik Date: Mon, 17 Jul 2023 18:16:02 +0000 Subject: [PATCH 24/56] docs/sp_SP: Add translation of process/contribution-maturity-model Translate Documentation/process/contribution-maturity-model.rst into Spanish Signed-off-by: Avadhut Naik Reviewed-by: Carlos Bilbao [ jc: fix added warning for nonexistent ref ] Signed-off-by: Jonathan Corbet Link: https://lore.kernel.org/r/20230717181602.3468421-1-avadhut.naik@amd.com --- .../process/contribution-maturity-model.rst | 120 ++++++++++++++++++ .../translations/sp_SP/process/index.rst | 1 + 2 files changed, 121 insertions(+) create mode 100644 Documentation/translations/sp_SP/process/contribution-maturity-model.rst diff --git a/Documentation/translations/sp_SP/process/contribution-maturity-model.rst b/Documentation/translations/sp_SP/process/contribution-maturity-model.rst new file mode 100644 index 000000000000..cc052ae8183d --- /dev/null +++ b/Documentation/translations/sp_SP/process/contribution-maturity-model.rst @@ -0,0 +1,120 @@ +..

Algunas de las conclusiones de esa discusión incluyeron +que las empresas que forman parte de la comunidad del kernel de Linux +necesitan permitir que los ingenieros sean mantenedores como parte de su +trabajo, para que puedan convertirse en lideres respetados y finalmente, +en mantenedores del kernel. Para apoyar una fuente solida de talento, se +debe permitir y alentar a los desarrolladores a asumir contribuciones +upstream, como revisar los parches de otras personas, reestructurar la +infraestructura del kernel y escribir documentación. + +Con ese fin, Technical Advisory Board (TAB) de la Fundación Linux propone +este Modelo de Madurez de Contribución al Kernel de Linux. Estas +expectativas comunes para la participación con la comunidad upstream +tienen como objetivo aumentar la influencia de los desarrolladores +individuales, aumentar la colaboración de las organizaciones y mejorar +la salud general del ecosistema del kernel de Linux. + +El TAB insta a las organizaciones a evaluar continuamente su modelo de +madurez de Código Abierto y comprometerse a realizar mejoras para +alinearse con este modelo. Para ser eficaz, esta evaluación debe +incorporar la reacción de toda la organización, incluyendo la gerencia +y los desarrolladores en todos los niveles de antigüedad. En el espíritu +de Código Abierto, alentamos a las organizaciones a publicar sus +evaluaciones y planes para mejorar su participación con la comunidad +upstream. + +Nivel 0 +======= + +* A los ingenieros de software no se les permite contribuir con parches + al kernel de Linux. + +Nivel 1 +======= + +* A los ingenieros de software se les permite contribuir con parches al + kernel de Linux, ya sea como parte de sus responsabilidades de trabajo + o en su propio tiempo. + +Nivel 2 +======= + +* Se espera que los ingenieros de software contribuyan al kernel de Linux + como parte de sus responsabilidades de trabajo. +* Se proporcionará apoyo a los ingenieros de software para asistir a + conferencias relacionadas con Linux como parte de su trabajo. +* Las contribuciones de código upstream de un ingeniero de software se + considerarán en la promoción y las revisiones de rendimiento. + +Nivel 3 +======= + +* Se espera que los ingenieros de software revisen los parches (incluidos + los parches escritos por ingenieros de otras empresas) como parte de + sus responsabilidades de trabajo. +* Contribuir con presentaciones o ponencias a conferencias relacionadas + con Linux o académicas (como las organizadas por la Fundación Linux, + Usenix, ACM, etc.), se consideran parte del trabajo de un ingeniero. +* Las contribuciones a la comunidad de un ingeniero de software se + considerarán en la promoción y las revisiones de rendimiento. +* Las organizaciones informarán regularmente sobre las métricas de sus + contribuciones de código abierto y harán un seguimiento de estas + métricas a lo largo del tiempo. Estas métricas pueden publicarse + solo internamente dentro de la organización, o a discreción de la + organización, algunas o todas pueden publicarse externamente. Las + métricas que se sugieren encarecidamente incluyen: + + * El número de contribuciones al kernel upstream por equipo u + organización (por ejemplo, todas las personas que reportan a un + gerente o director o vicepresidente). + * El porcentaje de desarrolladores del kernel que han realizado + contribuciones upstream relativo al total de desarrolladores + del kernel en la organización. + * El intervalo de tiempo entre los kernels utilizados en los servidores + y/o productos de la organización y la fecha de publicación del kernel + upstream en el que se basa el kernel interno. + * El número de commits fuera del árbol de desarrollo presentes en los + kernels internos. + +Nivel 4 +======= + +* Se anima a los ingenieros de software a pasar una parte de su tiempo de + trabajo centrado en el Trabajo Ascendente, que se define como revisar + parches, servir en los comités de programas, mejorar la infraestructura + del proyecto central como escribir o mantener pruebas, reducir la deuda + de tecnología upstream, escribir documentación, etc. +* Los ingenieros de software son apoyados para ayudar a organizar + conferencias relacionadas con Linux. +* Las organizaciones considerarán los comentarios de los miembros de la + comunidad en las revisiones oficiales de rendimiento. + +Nivel 5 +======= + +* El desarrollo del kernel upstream se considera un puesto de trabajo + formal, con al menos un tercio del tiempo del ingeniero pasado a hacer + el Trabajo Ascendente. +* Las organizaciones buscarán activamente las reacciones de los miembros + de la comunidad como un factor en las revisiones oficiales de + rendimiento. +* Las organizaciones informarán regularmente internamente sobre la ratio + de trabajo upstream a trabajo enfocado en perseguir directamente los + objetivos comerciales. diff --git a/Documentation/translations/sp_SP/process/index.rst b/Documentation/translations/sp_SP/process/index.rst index ed6851892661..09bfece0f52f 100644 --- a/Documentation/translations/sp_SP/process/index.rst +++ b/Documentation/translations/sp_SP/process/index.rst @@ -21,3 +21,4 @@ deprecated adding-syscalls researcher-guidelines + contribution-maturity-model From 16182e4a3e48429316f769ae8600cd28f95d04b0 Mon Sep 17 00:00:00 2001 From: Jonathan Corbet Date: Fri, 21 Jul 2023 14:44:47 -0600 Subject: [PATCH 25/56] docs: ABI: fix an RST error in sysfs-bus-nvdimm The literal blocks in this file lacked the necessary blank line at the top, causing Sphinx to complain: /Documentation/ABI/testing/sysfs-bus-nvdimm:11: WARNING: Unexpected indentation.

For the purposes of this document, the +``early boot process`` refers to any code that runs before the final virtual +mapping is set up. + +Pre-kernel Requirements and Constraints +======================================= + +The RISC-V kernel expects the following of bootloaders and platform firmware: + +Register state +-------------- + +The RISC-V kernel expects: + + * ``$a0`` to contain the hartid of the current core. + * ``$a1`` to contain the address of the devicetree in memory. + +CSR state +--------- + +The RISC-V kernel expects: + + * ``$satp = 0``: the MMU, if present, must be disabled. + +Reserved memory for resident firmware +------------------------------------- + +The RISC-V kernel must not map any resident memory, or memory protected with +PMPs, in the direct mapping, so the firmware must correctly mark those regions +as per the devicetree specification and/or the UEFI specification. + +Kernel location +--------------- + +The RISC-V kernel expects to be placed at a PMD boundary (2MB aligned for rv64 +and 4MB aligned for rv32). Note that the EFI stub will physically relocate the +kernel if that's not the case. + +Hardware description +-------------------- + +The firmware can pass either a devicetree or ACPI tables to the RISC-V kernel. + +The devicetree is either passed directly to the kernel from the previous stage +using the ``$a1`` register, or when booting with UEFI, it can be passed using the +EFI configuration table. + +The ACPI tables are passed to the kernel using the EFI configuration table. In +this case, a tiny devicetree is still created by the EFI stub. Please refer to +"EFI stub and devicetree" section below for details about this devicetree. + +Kernel entry +------------ + +On SMP systems, there are 2 methods to enter the kernel: + +- ``RISCV_BOOT_SPINWAIT``: the firmware releases all harts in the kernel, one hart + wins a lottery and executes the early boot code while the other harts are + parked waiting for the initialization to finish. This method is mostly used to + support older firmwares without SBI HSM extension and M-mode RISC-V kernel. +- ``Ordered booting``: the firmware releases only one hart that will execute the + initialization phase and then will start all other harts using the SBI HSM + extension. The ordered booting method is the preferred booting method for + booting the RISC-V kernel because it can support CPU hotplug and kexec. + +UEFI +---- + +UEFI memory map +~~~~~~~~~~~~~~~ + +When booting with UEFI, the RISC-V kernel will use only the EFI memory map to +populate the system memory. + +The UEFI firmware must parse the subnodes of the ``/reserved-memory`` devicetree +node and abide by the devicetree specification to convert the attributes of +those subnodes (``no-map`` and ``reusable``) into their correct EFI equivalent +(refer to section "3.5.4 /reserved-memory and UEFI" of the devicetree +specification v0.4-rc1). + +RISCV_EFI_BOOT_PROTOCOL +~~~~~~~~~~~~~~~~~~~~~~~ + +When booting with UEFI, the EFI stub requires the boot hartid in order to pass +it to the RISC-V kernel in ``$a1``. 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/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 From 180bb41d61b7f14fff5a73d703531540ed71fba7 Mon Sep 17 00:00:00 2001 From: Alexandre Ghiti Date: Thu, 17 Aug 2023 15:07:34 +0200 Subject: [PATCH 47/56] Documentation: riscv: Update boot image header since EFI stub is supported The EFI stub is supported on RISC-V so update the documentation that explains how the boot image header was reused to support it.
