2020-02-04kbuild: rename hostprogs-y/always to hostprogs/always-yMasahiro Yamada1-2/+2
In old days, the "host-progs" syntax was used for specifying host programs. It was renamed to the current "hostprogs-y" in 2004. It is typically useful in scripts/Makefile because it allows Kbuild to selectively compile host programs based on the kernel configuration. This commit renames like follows: always -> always-y hostprogs-y -> hostprogs So, 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 host program, irrespective of the kernel configuration. We want to specify which ones to compile by CONFIG options, so always-y will be handier. The "always", "hostprogs-y", "hostprogs-m" will be kept for backward compatibility for a while.

2020-01-28scripts/dtc: Revert "yamltree: Ensure consistent bracketing of properties with phandles"Rob Herring1-21/+0
This reverts upstream commit 18d7b2f4ee45fec422b7d82bab0b3c762ee907e4. A revert in upstream dtc is pending. This commit didn't work for properties such as 'interrupt-map' that have phandle in the middle of an entry. It would also not work for a 0 or -1 phandle value that acts as a NULL.

2019-05-18treewide: prefix header search paths with $(srctree)/Masahiro Yamada1-3/+3
Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks. Having whitespaces after -I does not matter since commit 48f6e3cf5bc6 ("kbuild: do not drop -I without parameter").

2018-12-13kbuild: Add support for DT binding schema checksRob Herring1-0/+4
This adds the build infrastructure for checking DT binding schema documents and validating dts files using the binding schema. Check DT binding schema documents: make dt_binding_check Build dts files and check using DT binding schema: make dtbs_check Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to use for validation. This makes it easier to find and fix errors generated by a specific schema. Currently, the validation targets are separate from a normal build to avoid a hard dependency on the external DT schema project and because there are lots of warnings generated.

2018-10-02kbuild: consolidate Devicetree dtb build rulesRob Herring1-1/+1
There is nothing arch specific about building dtb files other than their location 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 host compiler preprocessor is perfectly fine for building dtbs. Move the build rules to a common location and remove the arch specific ones. This is 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 be dtc. This change enables support 'dtbs_install' on some arches which were missing the target.

2018-08-22scripts/dtc: consolidate include path options in MakefileMasahiro Yamada1-14/+4
It is tedious to specify extra compiler options for every file.

On the other hand, -I$(src) is used to include check-in headers from generated C files. Thus, I added it only to dtc-lexer.lex.o and dtc-parser.tab.o .

2018-04-24dtc: checks: drop warning for missing PCI bridge bus-rangeRob Herring1-3/+2
Cherry-picked from dtc upstream commit e1f139ea4900fd0324c646822b4061fec6e08321. Having a 'bus-range' property for PCI bridges should not be required, so remove the warning when missing. There was some confusion with the Linux kernel printing a message that no property is present and the OS assigned the bus number. This message was intended to be informational rather than a warning. When the firmware doesn't enumerate the PCI bus and leaves it up to the OS to do, then it is perfectly fine for the OS to assign bus numbers and bus-range is not necessary. There are a few cases where bus-range is needed or useful as Arnd Bergmann summarized: - Traditionally Linux avoided using multiple PCI domains, but instead configured separate PCI host bridges to have non-overlapping bus ranges so we can present them to user space as a single domain, and run the kernel without CONFIG_PCI_DOMAINS. Specifying the bus ranges this way would and give stable bus numbers across boots when the probe order is not fixed. - On certain ARM64 systems, we must only use the first 128 bus numbers based on the way the IOMMU identifies the device with truncated bus/dev/fn number. There are probably others like this, with various limitations. - To leave some room for hotplugged devices, each slot on a host bridge can in theory get a range of bus numbers that are available when assigning bus numbers at boot time Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Rob Herring <robh@kernel.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2018-04-07kbuild: add %.lex.c and %.tab.[ch] to 'targets' automaticallyMasahiro Yamada1-3/+0
Files generated by if_changed* must be added to 'targets' to include *.cmd files. Otherwise, they would be regenerated every time. The build system automatically adds objects to 'targets' where appropriate, such as obj-y, extra-y, etc. but does nothing for intermediate files. So, each Makefile needs to add them by itself. There are some common cases where objects are generated by chained rules. Lexers and parsers are compiled like follows: %.lex.o <- %.lex.c <- %.l %.tab.o <- %.tab.c <- %.y They are common patterns, so it is reasonable to take care of them in the core Makefile instead of requiring each Makefile to do so. At this moment, you cannot delete 'target += zconf.lex.c' in the Kconfig Makefile because zconf.lex.c is included from zconf.tab.c instead of being compiled separately. It should be deleted after Kconfig is more refactored. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Frank Rowand <frowand.list@gmail.com>

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman3-0/+3
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license 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 binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the 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 cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base 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 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately 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 license identifiers 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 the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version 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 correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

As the comparison uses process substitution to pass files after conversion to DTS format, the diff header doesn't show the real filenames, but the names of the file descriptors used: --- /dev/fd/63 2017-06-22 11:21:47.531637188 +0200 +++ /dev/fd/62 2017-06-22 11:21:47.531637188 +0200 This is especially annoying when comparing a bunch of DT files in a loop, as the output doesn't show a clue about which files it refers to.

2017-05-18devicetree: Move include prefixes from arch to separate directoryOlof Johansson15-0/+15
We use a directory under arch/$ARCH/boot/dts as an include path that has links outside of the subtree to find dt-bindings from under include/dt-bindings. That's been working well, but new DT architectures haven't been adding them by default. Recently there's been a desire to share some of the DT material between arm and arm64, which originally caused developers to create symlinks or relative includes between the subtrees. This isn't ideal -- it breaks if the DT files aren't stored in the exact same hierarchy as the kernel tree, and generally it's just icky. As a somewhat cleaner solution we decided to add a $ARCH/ prefix link once, and allow DTS files to reference dtsi (and dts) files in other architectures that way. Original approach was to create these links under each architecture, but it lead to the problem of recursive symlinks. As a remedy, move the include link directories out of the architecture trees into a common location. At the same time, they can now share one directory and one dt-bindings/ link as well.

2016-07-22scripts/dtc: dt_to_config - kernel config options for a devicetreeGaurav Minocha2-1/+1214
Determining which kernel config options need to be enabled for a given devicetree can be a painful process. Create a new tool to find the drivers that may match a devicetree node compatible, find the kernel config options that enable the driver, and optionally report whether the kernel config option is enabled.

2015-04-29scripts/dtc: add missing libfdt and fixups to import scriptGaurav Minocha1-0/+9
The following script is used to import dtc upstream into kernel. It was missing import of dtc/libfdt, with this commit it will include the same. Also, currently in arch and driver code that needs early access to the flattened device tree it is necessary to add specific CFLAGS so that when scripts/dtc/libfdt/libfdt.h is included the C preprocessor is able to locate the libfdt versions of libfdt_env.h and fdt.h without generating an error. So, this script replaces angular brackets with quotation used to include header files fdt.h and libfdt_env.h Signed-off-by: Gaurav Minocha <gaurav.minocha.os@gmail.com> [robh: reword commit headline and add 'git add'] Signed-off-by: Rob Herring <robh@kernel.org>
