2018-12-13kbuild: Add support for DT binding schema checksRob Herring1-0/+1
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.

2018-04-11clang-format: add configuration fileMiguel Ojeda1-0/+1
clang-format is a tool to format C/C++/... code according to a set of rules and heuristics. Like most tools, it is not perfect nor covers every single case, but it is good enough to be helpful. In particular, it is useful for quickly re-formatting blocks of code automatically, for reviewing full files in order to spot coding style mistakes, typos and possible improvements. It is also handy for sorting ``#includes``, for aligning variables and macros, for reflowing text and other similar tasks. It also serves as a teaching tool/guide for newcomers. The tool itself has been already included in the repositories of popular Linux distributions for a long time. The rules in this file are intended for clang-format >= 4, which is easily available in most distributions. This commit adds the configuration file that contains the rules that the tool uses to know how to format the code according to the kernel coding style. This gives us several advantages: * clang-format works out of the box with reasonable defaults; avoiding that everyone has to re-do the configuration. * Everyone agrees (eventually) on what is the most useful default configuration for most of the kernel. * If it becomes commonplace among kernel developers, clang-format may feel compelled to support us better. They already recognize the Linux kernel and its style in their documentation and in one of the style sub-options. Some of clang-format's features relevant for the kernel are: * Uses clang's tooling support behind the scenes to parse and rewrite the code. It is not based on ad-hoc regexps. * Supports reasonably well the Linux kernel coding style. * Fast enough to be used at the press of a key. * There are already integrations (either built-in or third-party) for many common editors used by kernel developers (e.g. vim, emacs, Sublime, Atom...) that allow you to format an entire file or, more usefully, just your selection. * Able to parse unified diffs -- you can, for instance, reformat only the lines changed by a git commit. * Able to reflow text comments as well. * Widely supported and used by hundreds of developers in highly complex projects and organizations (e.g. the LLVM project itself, Chromium, WebKit, Google, Mozilla...). Therefore, it will be supported for a long time.

2018-04-07kbuild: rename *-asn1.[ch] to *.asn1.[ch]Masahiro Yamada1-1/+1

2017-12-12scripts/package: snap-pkg targetPaolo Pisati1-0/+5
Following in footsteps of other targets like 'deb-pkg, 'rpm-pkg' and 'tar-pkg', this patch adds a 'snap-pkg' target for the creation of a Linux kernel snap package using the kbuild infrastructure. A snap, in its general form, is a self contained, sandboxed, universal package and it is intended to work across multiple distributions and/or devices. A snap package is distributed as a single compressed squashfs filesystem. A kernel snap is a snap package carrying the Linux kernel, kernel modules, accessory files (DTBs, System.map, etc) and a manifesto file. The purpose of a kernel snap is to carry the Linux kernel during the creation of a system image, eg. Ubuntu Core, and its subsequent upgrades.

2016-07-22scripts: add Linux .cocciconfig for coccinelleLuis R. Rodriguez1-0/+1
Coccinelle supports reading .cocciconfig, the order of precedence for variables for .cocciconfig is as follows: o Your current user's home directory is processed first o Your directory from which spatch is called is processed next o The directory provided with the --dir option is processed last, if used Since coccicheck runs through make, it naturally runs from the kernel proper dir, as such the second rule above would be implied for picking up a .cocciconfig when using 'make coccicheck'. 'make coccicheck' also supports using M= targets.If you do not supply any M= target, it is assumed you want to target the entire kernel. The kernel coccicheck script has: if [ "$KBUILD_EXTMOD" = "" ] ; then OPTIONS="--dir $srctree $COCCIINCLUDE" else OPTIONS="--dir $KBUILD_EXTMOD $COCCIINCLUDE" fi KBUILD_EXTMOD is set when an explicit target with M= is used. For both cases the spatch --dir argument is used, as such third rule applies when whether M= is used or not, and when M= is used the target directory can have its own .cocciconfig file. When M= is not passed as an argument to coccicheck the target directory is the same as the directory from where spatch was called. If not using the kernel's coccicheck target, keep the above precedence order logic of .cocciconfig reading. If using the kernel's coccicheck target, override any of the kernel's .coccicheck's settings using SPFLAGS. We help Coccinelle when used against Linux with a set of sensible defaults options for Linux with our own Linux .cocciconfig. This hints to coccinelle git can be used for 'git grep' queries over coccigrep. A timeout of 200 seconds should suffice for now. The options picked up by coccinelle when reading a .cocciconfig do not appear as arguments to spatch processes running on your system, to confirm what options will be used by Coccinelle run: spatch --print-options-only You can override with your own preferred index option by using SPFLAGS. Coccinelle supports both glimpse and idutils. Glimpse had historically provided the best performance, however recent benchmarks reveal idutils is performing just as well. Due to some recent fixes however you however will need at least coccinelle >= 1.0.6 if using idutils. Coccinelle carries a script scripts/idutils_index.sh which creates the idutils database with as follows: mkid -i C --output .id-utils.index If using just "--use-idutils" coccinelle expects your idutils database to be on the top level of the kernel as a file named ".id-utils.index". If you do not use this you can symlink your database file to it, or you can specify the database file following the "--use-idutils" argument. Examples: make SPFLAGS=--use-idutils coccicheck This assumes you have $srctree/.id-utils.index, where $srctree is the top level of the kernel. make SPFLAGS="--use-idutils /full-path/to/ID" coccicheck Here you specify the full path of the idutils ID database. Using .cocciconfig is possible, however given the order of precedence followed by Coccinelle, and since the kernel now carries its own .cocciconfig, you will need to use SPFLAGS to use idutils if desired. v4: o Recommend upgrade for using idutils with coccinelle due to some recent fixes. o Refer to using --print-options-only for testing what options are picked up by .cocciconfig reading. o Expand commit log considerably explaining *why* .cocconfig from two precedence rules are used when using coccicheck, and how to properly override these if needed. o Expand Documentation/coccinelle.txt v3: Expand commit log a bit more Signed-off-by: Luis R.

2016-06-07GCC plugin infrastructureEmese Revfy1-0/+1
This patch allows to build the whole kernel with GCC plugins. It was ported from grsecurity/PaX. The infrastructure supports building out-of-tree modules and building in a separate directory. Cross-compilation is supported too. Currently the x86, arm, arm64 and uml architectures enable plugins. The directory of the gcc plugins is scripts/gcc-plugins. You can use a file or a directory there. The plugins compile with these options: * -fno-rtti: gcc is compiled with this option so the plugins must use it too * -fno-exceptions: this is inherited from gcc too * -fasynchronous-unwind-tables: this is inherited from gcc too * -ggdb: it is useful for debugging a plugin (better backtrace on internal errors) * -Wno-narrowing: to suppress warnings from gcc headers (ipa-utils.h) * -Wno-unused-variable: to suppress warnings from gcc headers (gcc_version variable, plugin-version.h) The infrastructure introduces a new Makefile target called gcc-plugins. It supports all gcc versions from 4.5 to 6.0. The scripts/gcc-plugin.sh script chooses the proper host compiler (gcc-4.7 can be built by either gcc or g++). This script also checks the availability of the included headers in scripts/gcc-plugins/gcc-common.h. The gcc-common.h header contains frequently included headers for GCC plugins and it has a compatibility layer for the supported gcc versions. The gcc-generate-*-pass.h headers automatically generate the registration structures for GIMPLE, SIMPLE_IPA, IPA and RTL passes. Note that 'make clean' keeps the *.so files (only the distclean or mrproper targets clean all) because they are needed for out-of-tree modules. Based on work created by the PaX Team.

The current rule for generating signing_key.priv and signing_key.x509 is a classic example of a bad rule which has a tendency to break parallel make. When invoked to create *either* target, it generates the other target as a side-effect that make didn't predict. So let's switch to using a single file signing_key.pem which contains both key and certificate. That matches what we do in the case of an external key specified by CONFIG_MODULE_SIG_KEY anyway, so it's also slightly cleaner.

2014-07-30kbuild: Support split debug info v4Andi Kleen1-0/+1
This is an alternative approach to lower the overhead of debug info (as we discussed a few days ago) gcc 4.7+ and newer binutils have a new "split debug info" debug info model where the debug info is only written once into central ".dwo" files. This avoids having to copy it around multiple times, from the object files to the final executable. It lowers the disk space requirements. In addition it defaults to compressed debug data. More details here: http://gcc.gnu.org/wiki/DebugFission This patch adds a new option to enable it. It has to be an option, because it'll undoubtedly break everyone's debuginfo packaging scheme. gdb/objdump/etc. all still work, if you have new enough versions. I don't see big compile wins (maybe a second or two faster or so), but the object dirs with debuginfo get significantly smaller. My standard kernel config (slightly bigger than defconfig) shrinks from 2.9G disk space to 1.1G objdir (with non reduced debuginfo). I presume if you are IO limited the compile time difference will be larger. Only problem I've seen so far is that it doesn't play well with older versions of ccache (apparently fixed, see https://bugzilla.samba.org/show_bug.cgi?id=10005) v2: various fixes from Dirk Gouders.

Since userspace headers were moved to generated/uapi it possible to have a stale copy of linux/version.h at that file's old location. This causes confusion after building an older kernel version, then checking out and building a new one; the old (stale) version header will still get picked up until it is manually removed. This upsets the C library. Since the uapi changes, include/linux/version.h is no longer generated and should not be ignored, so this patch removes it from .gitignore.

2011-04-28kbuild: asm-generic supportSam Ravnborg1-0/+1
There is an increasing amount of header files shared between individual architectures in asm-generic. To avoid a lot of dummy wrapper files that just include the corresponding file in asm-generic provide some basic support in kbuild for this. With the following patch an architecture can maintain a list of files in the file arch/$(ARCH)/include/asm/Kbuild To use a generic file just add: generic-y += <name-of-header-file.h> For each file listed kbuild will generate the necessary wrapper in arch/$(ARCH)/include/generated/asm. When installing userspace headers a wrapper is likewise created. The original inspiration for this came from the unicore32 patchset - although a different method is used. The patch includes several improvements from Arnd Bergmann. Michael Marek contributed Makefile.asm-generic. Remis Baima did an intial implementation along to achive the same - see https://patchwork.kernel.org/patch/13352/ Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Guan Xuetao <guanxuetao@mprc.pku.edu.cn> Tested-by: Guan Xuetao <guanxuetao@mprc.pku.edu.cn> Acked-by: Arnd Bergmann <arnd@arndb.de> Cc: Remis Lima Baima <remis.developer@googlemail.com> Signed-off-by: Michal Marek <mmarek@suse.cz>

2010-03-13Fix up .gitignore for top-level file patternsLinus Torvalds1-8/+12
Some of the gitignore file patters were explicitly meant to be only for the top level, but weren't marked that way, so they would trigger recursively in subdirectories too. Normally that was harmless, but at least "linux" happened to trigger elsewhere too. Fix it up. And other patterns in that section weren't necessarily top-level at all.

2009-12-12kbuild: generate modules.builtinMichal Marek1-0/+1
To make it easier for module-init-tools and scripts like mkinitrd to distinguish builtin and missing modules, install a modules.builtin file listing all builtin modules. This is done by generating an additional config file (tristate.conf) with tristate options set to uppercase 'Y' or 'M'. If we source that config file, the builtin modules appear in obj-Y.

We no longer use this directory for generated files and all architectures has moved their header files so no symlink tricks are needed either. Drop the symlink and drop the ARCH check.
