kbuild: allow to combine multiple V= levelsCommit a6de553da01c ("kbuild: Allow to combine multiple W= levels")supported W=123 to enable all the extra warning groups.I think a similar idea is applicable to the V= option. V=1 echos the whole command V=2 prints the reason for rebuildingThese are orthogonal, and can be enabled at the same time.This commit supports V=12 to enable both of them.Signed-off-by: Masahiro Yamada Tested-by: Nicolas Schier Reviewed-by: Nicolas Schier List of files: /linux-6.15/arch/x86/tools/Makefile

c8d7b7e5 - x86/tools: Use tools headers for instruction decoder selftests

Thu, 12 Nov 2020 23:03:20 +0000

x86/tools: Use tools headers for instruction decoder selftestsCurrently the x86 instruction decoder is used from:- the kernel itself,- from tools like objtool and perf,- within x86 tools, i.e. instruction decoder selftests.The first two cases are similar, because tools headers try to mimickernel headers.Instruction decoder selftests include some of the kernel headersdirectly, including uapi headers. This works until headers dependenciesare kept to a minimum and tools are not cross-compiled. Since the goalof the x86 instruction decoder selftests is not to verify uapi headers,move it to using tools headers, like is already done for vdso2c tool,mkpiggy and other tools in arch/x86/boot/.Signed-off-by: Vasily Gorbik Acked-by: Peter Zijlstra (Intel) Acked-by: Masami Hiramatsu Signed-off-by: Josh Poimboeuf List of files: /linux-6.15/arch/x86/tools/Makefile

5f2fb52f - kbuild: rename hostprogs-y/always to hostprogs/always-y

Sat, 01 Feb 2020 16:49:24 +0000

kbuild: rename hostprogs-y/always to hostprogs/always-yIn old days, the "host-progs" syntax was used for specifying hostprograms. It was renamed to the current "hostprogs-y" in 2004.It is typically useful in scripts/Makefile because it allows Kbuild toselectively compile host programs based on the kernel configuration.This commit renames like follows: always -> always-y hostprogs-y -> hostprogsSo, scripts/Makefile will look like this: always-$(CONFIG_BUILD_BIN2C) += ... always-$(CONFIG_KALLSYMS) += ... ... hostprogs := $(always-y) $(always-m)I think this makes more sense because a host program is always a hostprogram, irrespective of the kernel configuration. We want to specifywhich ones to compile by CONFIG options, so always-y will be handier.The "always", "hostprogs-y", "hostprogs-m" will be kept for backwardcompatibility for a while.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/x86/tools/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/arch/x86/tools/Makefile

Tue, 08 May 2012 18:22:24 +0000

x86, realmode: 16-bit real-mode code support for relocs toolA new option is added to the relocs tool called '--realmode'.This option causes the generation of 16-bit segment relocationsand 32-bit linear relocations for the real-mode code. Whenthe real-mode code is moved to the low-memory during kernelinitialization, these relocation entries can be used torelocate the code properly.In the assembly code 16-bit segment relocations must be relativeto the 'real_mode_seg' absolute symbol. Linear relocations must berelative to a symbol prefixed with 'pa_'.16-bit segment relocation is used to load cs:ip in 16-bit code.Linear relocations are used in the 32-bit code for relocatabledata references. They are declared in the linker script of thereal-mode code.The relocs tool is moved to arch/x86/tools/relocs.c, and added newtarget archscripts that can be used to build scripts needed buildingan architecture. be compiled before building the arch/x86 tree.[ hpa: accelerating this because it detects invalid absolute relocations, a serious bug in binutils 2.22.52.0.x which currently produces bad kernels. ]Signed-off-by: H.
