a5575df5 - kbuild: unify cmd_copy and cmd_shipped

Tue, 25 Jan 2022 06:40:27 +0000

kbuild: unify cmd_copy and cmd_shippedcmd_copy and cmd_shipped have similar functionality. The difference isthat cmd_copy uses 'cp' while cmd_shipped 'cat'.Unify them into cmd_copy because this macro name is more intuitive.Going forward, cmd_copy will use 'cat' to avoid the permission issue.I also thought of 'cp --no-preserve=mode' but this option is notmentioned in the POSIX spec [1], so I am keeping the 'cat' command.[1]: https://pubs.opengroup.org/onlinepubs/009695299/utilities/cp.htmlSigned-off-by: Masahiro Yamada Reviewed-by: Nick Desaulniers Reviewed-by: Gabriel Krisman Bertazi List of files: /linux-6.15/scripts/dtc/include-prefixes/microblaze/Makefile

microblaze: remove the explicit removal of system.dtbI guess || (rm -f $@ && echo false)... should be || (rm -f $@ && false)In fact, no Makefile needs to delete a target explicitly on error.It is automatically done since commit 9c2af1c7377a ("kbuild: add.DELETE_ON_ERROR special target").I also reused equivalent cmd_shipped from scripts/Makefile.lib.Signed-off-by: Masahiro Yamada Signed-off-by: Michal Simek List of files: /linux-6.15/scripts/dtc/include-prefixes/microblaze/Makefile

37c8a5fa - kbuild: consolidate Devicetree dtb build rules

Wed, 10 Jan 2018 21:19:37 +0000

kbuild: consolidate Devicetree dtb build rulesThere is nothing arch specific about building dtb files other than theirlocation under /arch/*/boot/dts/. Keeping each arch aligned is a pain.The dependencies and supported targets are all slightly different.Also, a cross-compiler for each arch is needed, but really the hostcompiler preprocessor is perfectly fine for building dtbs. Move thebuild rules to a common location and remove the arch specific ones. Thisis done in a single step to avoid warnings about overriding rules.The build dependencies had been a mixture of 'scripts' and/or 'prepare'.These pull in several dependencies some of which need a target compiler(specifically devicetable-offsets.h) and aren't needed to build dtbs.All that is really needed is dtc, so adjust the dependencies to only bedtc.This change enables support 'dtbs_install' on some arches which weremissing the target.Acked-by: Will Deacon Acked-by: Paul Burton Acked-by: Ley Foon Tan Acked-by: Masahiro Yamada Cc: Michal Marek Cc: Vineet Gupta Cc: Russell King Cc: Catalin Marinas Cc: Yoshinori Sato Cc: Michal Simek Cc: Ralf Baechle Cc: James Hogan Cc: Benjamin Herrenschmidt Cc: Paul Mackerras Cc: Michael Ellerman Cc: Chris Zankel Cc: Max Filippov Cc: linux-kbuild@vger.kernel.orgCc: linux-snps-arc@lists.infradead.orgCc: linux-arm-kernel@lists.infradead.orgCc: uclinux-h8-devel@lists.sourceforge.jpCc: linux-mips@linux-mips.orgCc: nios2-dev@lists.rocketboards.orgCc: linuxppc-dev@lists.ozlabs.orgCc: linux-xtensa@linux-xtensa.orgSigned-off-by: Rob Herring List of files: /linux-6.15/scripts/dtc/include-prefixes/microblaze/Makefile

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/scripts/dtc/include-prefixes/microblaze/Makefile

300db34a - microblaze: use new common dtc rule

Tue, 27 Nov 2012 23:29:15 +0000

microblaze: use new common dtc ruleThe current rules have the .dtb files build in a different directoryfrom the .dts files. This patch changes microblaze to use the generic dtbrule which builds .dtb files in the same directory as the source .dts.This requires moving parts of arch/microblaze/boot/Makefile into newlycreated arch/microblaze/boot/dts/Makefile, and updatingarch/microblaze/Makefile to call the new Makefile. linked_dtb.S is alsomoved into boot/dts/ since it's used by rules that were moved.Cc: Michal Simek Cc: microblaze-uclinux@itee.uq.edu.auSigned-off-by: Stephen Warren Signed-off-by: Rob Herring List of files: /linux-6.15/scripts/dtc/include-prefixes/microblaze/Makefile
