2560cffd - ARM: Delete ARM11MPCore (ARM11 ARMv6K SMP) support

Thu, 07 Dec 2023 13:33:35 +0000

ARM: Delete ARM11MPCore (ARM11 ARMv6K SMP) supportThis ARM11 SMP configuration was one of the first SMP configurationsthe ARM kernel supported, but it has the downside of odd DMA handling,odd cache tagging, and often (as of recent) completely broken cachehandling on the ARM RealView PB11MPCore test chips. To boot theplatform it was necessary to completely disable the cache.When it comes to the EB 11MPCore it is unclear if this ever worked.These reference designs are now the only ARMv6K SMP platforms.As only reference designs of purely academic interest remain, andsince the special-cased DMA and PMU code is hard to maintain anddoesn't really work, it is not really worth our time.Delete the ARM11MPCore support along with:- The special DMA quirk CONFIG_DMA_CACHE_RWFO that is only used on ARMv6K SMP, and we are the last ARMV6K system leaving the building and the cache handling is awkward, so good-bye.- The special PMU handling that was only used by ARM11MPCore.The following is left behind:- TIMER_OF_DECLARE(arm_twd_11mp, "arm,arm11mp-twd-timer", ...) in arch/arm/kernel/smp_twd.c, this is still in use by Marvell MMP3 arch/arm/boot/dts/marvell/mmp3.dtsi- IRQCHIP_DECLARE(arm11mp_gic, "arm,arm11mp-gic", ...) in drivers/irqchip/irq-gic.c, this is still in use by Marvell MMP3 arch/arm/boot/dts/marvell/mmp3.dtsi- A compatible for the arm11mpcore SCU, since this was mistakedly used for the Cortex-A9 version of RealView EB.These are unfortunate but will need to be kept around forcompatibility. New Marvell-specific compatibles should however probablybe added.Acked-by: Mark Rutland Reviewed-by: Arnd Bergmann Signed-off-by: Linus Walleij Acked-by: Liviu Dudau Link: https://lore.kernel.org/r/20231207-drop-11mpcore-v2-1-560b396f3bf5@linaro.orgSigned-off-by: Arnd Bergmann List of files: /linux-6.15/arch/arm/mach-versatile/Kconfig

3ebe59a5 - ata: clean up how architectures enable PATA_PLATFORM and PATA_OF_PLATFORM

Wed, 14 Sep 2022 14:27:12 +0000

ata: clean up how architectures enable PATA_PLATFORM and PATA_OF_PLATFORMThere are two options for platform device PATA support: PATA_PLATFORM: Generic platform device PATA support PATA_OF_PLATFORM: OpenFirmware platform device PATA supportIf an architecture allows the generic platform device PATA support, itshall select HAVE_PATA_PLATFORM. Then, Generic platform device PATA supportis available and can be selected.If an architecture has OpenFirmware support, which it indicates byselecting OF, OpenFirmware platform device PATA support is availableand can be selected.If OpenFirmware platform device PATA support is selected, then thefunctionality (code files) from Generic platform device PATA support needsto be integrated in the kernel build for the OpenFirmware platform devicePATA support to work. Select PATA_PLATFORM in PATA_OF_PLATFORM to make surethe needed files are added in the build.So, architectures with OpenFirmware support, do not need to additionallyselect HAVE_PATA_PLATFORM. It is only needed by architecture that want thenon-OF pata-platform module.Reflect this way of intended use of config symbols in the ata Kconfig andadjust all architecture definitions.This follows the suggestion from Arnd Bergmann (see Link).Suggested-by: Arnd Bergmann Link: https://lore.kernel.org/all/4b33bffc-2b6d-46b4-9f1d-d18e55975a5a@www.fastmail.com/Signed-off-by: Lukas Bulwahn Reviewed-by: Arnd Bergmann Signed-off-by: Damien Le Moal List of files: /linux-6.15/arch/arm/mach-versatile/Kconfig

5d6f5267 - ARM: rework endianess selection

Mon, 04 Apr 2022 09:52:31 +0000

ARM: rework endianess selectionChoosing big-endian vs little-endian kernels in Kconfig has not workedcorrectly since the introduction of CONFIG_ARCH_MULTIPLATFORM a longtime ago.The problems is that CONFIG_BIG_ENDIAN depends onARCH_SUPPORTS_BIG_ENDIAN, which can set by any one platformin the config, but would actually have to be supported by allof them.This was mostly ok for ARMv6/ARMv7 builds, since these are BE8 andtend to just work aside from problems in nonportable device drivers.For ARMv4/v5 machines, CONFIG_BIG_ENDIAN and CONFIG_ARCH_MULTIPLATFORMwere never set together, so this was disabled on all those machinesexcept for IXP4xx.As IXP4xx can now become part of ARCH_MULTIPLATFORM, it seems better toformalize this logic: all ARMv4/v5 platforms get an explicit dependencyon being either big-endian (ixp4xx) or little-endian (the rest). We maywant to fix ixp4xx in the future to support both, but it does not workin LE mode at the moment.For the ARMv6/v7 platforms, there are two ways this could be handled a) allow both modes only for platforms selecting 'ARCH_SUPPORTS_BIG_ENDIAN' today, but only LE mode for the others, given that these were added intentionally at some point. b) allow both modes everwhere, given that it was already possible to build that way by e.g. selecting ARCH_VIRT, and that the list is not an accurate reflection of which platforms may or may not work.Out of these, I picked b) because it seemed slighly more logicalto me.Signed-off-by: Arnd Bergmann List of files: /linux-6.15/arch/arm/mach-versatile/Kconfig

b2441318 - License cleanup: add SPDX GPL-2.0 license identifier to files with no license

Wed, 01 Nov 2017 14:07:57 +0000

License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseMany source files in the tree are missing licensing information, whichmakes it harder for compliance tools to determine the correct license.By default all files without license information are under the defaultlicense of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'SPDX license identifier. The SPDX identifier is a legally bindingshorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart andPhilippe Ombredanne.How this work was done:Patches were generated and checked against linux-4.14-rc6 for a subset ofthe use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up caseswhere non-standard license headers were used, and references to licensehad to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied toa file was done in a spreadsheet of side by side results from of theoutput of two independent scanners (ScanCode & Windriver) producing SPDXtag:value files created by Philippe Ombredanne. Philippe prepared thebase worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 filesassessed. Kate Stewart did a file by file comparison of the scannerresults in the spreadsheet to determine which SPDX license identifier(s)to be applied to the file. She confirmed any determination that was notimmediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines).All documentation files were explicitly excluded.The following heuristics were used to determine which SPDX licenseidentifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time.In total, over 70 hours of logged manual review was done on thespreadsheet to determine the SPDX license identifiers to apply to thesource files by Kate, Philippe, Thomas and, in some cases, confirmationby lawyers working with the Linux Foundation.Kate also obtained a third independent scan of the 4.13 code base fromFOSSology, and compared selected files where the other two scannersdisagreed against that SPDX file, to see if there was new insights. TheWindriver scanner is based on an older version of FOSSology in part, sothey are related.Thomas did random spot checks in about 500 files from the spreadsheetsfor the uapi headers and agreed with SPDX license identifier in thefiles he inspected. For the non-uapi files Thomas did random spot checksin about 15000 files.In initial set of patches against 4.14-rc6, 3 files were found to havecopy/paste license identifier errors, and have been fixed to reflect thecorrect identifier.Additionally Philippe spent 10 hours this week doing a detailed manualinspection and review of the 12,461 patched files from the initial patchversion early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correctThis produced a worksheet with 20 files needing minor correction. Thisworksheet was then exported into 3 different .csv files for thedifferent types of files to be modified.These .csv files were then reviewed by Greg. Thomas wrote a script toparse the csv files and add the proper SPDX tag to the file, in theformat that the file expected. This script was further refined by Gregbased on the output to detect more types of files automatically and todistinguish between header and source .c files (which need differentcomment types.) Finally Greg ran the script using the .csv files togenerate the patches.Reviewed-by: Kate Stewart Reviewed-by: Philippe Ombredanne Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/arch/arm/mach-versatile/Kconfig

Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list.lets sort all our select statements alphanumerically.
