2016-12-07linux: generate KBUILD_BUILD_TIMESTAMP date whith LC_ALL=CJean-Baptiste Trédez
Fix kernel reproducible build if a non-C locale is used on the host system. When building the Linux kernel, scripts/gen_initramfs_list.sh does 'date -d"$KBUILD_BUILD_TIMESTAMP" +%s'. In linux.mk, Buildroot sets KBUILD_BUILD_TIMESTAMP to "$(shell date -d @$(SOURCE_DATE_EPOCH))". For example, if LANG=fr_FR.UTF-8 is defined in the host system, it does not work: - LC_ALL=C date -d"$(LC_ALL=C date)" : ok - LC_ALL=C date -d"$(LC_ALL=fr_FR.UTF-8 date)" : error LANG/LC_ALL variables exported in the main Makefiles are not passed in the $(shell ...) sub-shells.

2016-09-22linux/tools: make it a real, separate packageYann E. MORIN
The kernel source tree also contains the sources for various userland tools, of which cpupower, perf or selftests. Currently, we have support for building those tools as part of the kernel build procedure. This looked the correct thing to do so far, because, well, they *are* part of the kernel source tree and some really have to be the same version as the kernel that will run. However, this is causing quite a non-trivial-to-break circular dependency in some configurations. For example, this defconfig fails to build (similar to the one reported by Paul): BR2_arm=y BR2_cortex_a7=y BR2_ARM_FPU_NEON_VFPV4=y BR2_TOOLCHAIN_EXTERNAL=y BR2_INIT_SYSTEMD=y BR2_LINUX_KERNEL=y BR2_LINUX_KERNEL_CUSTOM_GIT=y BR2_LINUX_KERNEL_CUSTOM_REPO_URL="https://github.com/raspberrypi/linux.git" BR2_LINUX_KERNEL_CUSTOM_REPO_VERSION="26f3b72a9c049be10e6af196252283e1f6ab9d1f" BR2_LINUX_KERNEL_DEFCONFIG="bcm2709" BR2_PACKAGE_LINUX_TOOLS_CPUPOWER=y BR2_PACKAGE_CRYPTODEV=y BR2_PACKAGE_OPENSSL=y BR2_PACKAGE_LIBCURL=y This causes a circular dependency, as explained by Thomas: - When libcurl is enabled, systemd depends on it - When OpenSSL is enabled, obviously, will use it for SSL support - When cryptodev-linux is enabled, OpenSSL will depend on it to use crypto accelerators supported in the kernel via cryptodev-linux. - cryptodev-linux being a kernel module, it depends on linux - linux by itself (the kernel) does not depend on pciutils, but the linux tool "cpupower" (managed in linux-tool-cpupower) depends on pciutils - pciutils depends on udev when available - udev is provided by systemd. And indeed, during the build, we can see that make warns (it's only reported as a *warning*, not as an actual error): [...] make[1]: Circular /home/ymorin/dev/buildroot/O/build/openssl-1.0.2h/.stamp_configured <- cryptodev-linux dependency dropped. >>> openssl 1.0.2h Downloading [...] So the build fails later on, when openssl is actually built: eng_cryptodev.c:57:31: fatal error: crypto/cryptodev.h: No such file or directory compilation terminated. <builtin>: recipe for target 'eng_cryptodev.o' failed Furthermore, graph-depends also detects the circular dependency, but treats it as a hard-error: Recursion detected for : cryptodev-linux which is a dependency of: openssl which is a dependency of: libcurl which is a dependency of: systemd which is a dependency of: udev which is a dependency of: pciutils which is a dependency of: linux which is a dependency of: cryptodev-linux Makefile:738: recipe for target 'graph-depends' failed Of course, there is no way to break the loop without losing functionality in either one of the involved packages *and* keep our infrastructure and packages as-is. The only solution is to break the loop at the linux-tools level, by moving them away into their own package, so that the linux package will no longer have the opportunity to depend on another package via a dependency of one the tools. All three linux tools are thus moved away to their own package. The package infrastructure only knows of three types of packages: those in package/ , in boot/ , in toolchain/ and the one in linux/ . So we create that new linux-tools package in package/ so that we don't have to fiddle with yet another special case in the infra. Still, we want its configure options to appear in the kernel's sub-menu. So, we make it a prompt-less package, with only the tools visible as options of that package, but without the usual dependency on their master symbol; they only depend on the Linux kernel. Furthermore, because the kernel is such a huge pile of code, we would not be very happy to extract it a second time just for the sake of a few tools. We can't extract only the tools/ sub-directory from the kernel source either, because some tools have hard-coded path to includes from the kernel (arch and stuff). Instead, we just use the linux source tree as our own build tree, and ensure the linux tree is extracted and patched before linux-tools is configured and built. Signed-off-by: "Yann E.

2016-09-19linux: use INSTALL_MOD_STRIP=1 to strip modulesAlexey Brodkin
We used to do a special handling of Linux kernel modules when stripping target binaries because there's some special precious data in modules that we must keep for them to properly operate. This is for example true for stack unwinding data etc. It turned out there're cases when our existing "strip --strip-unneeded" doesn't work well. For example this removes .debug_frame section used by Linux on ARC for stack unwinding, refer to [1] and [2] for more details. Now Linux kernel may strip modules as a part of "modules_install" target if INSTALL_MOD_STRIP=1 is passed in command line. And so we'll do allowing kernel decide how to strip modules in the best way. Still note as of today Linux kernel strips modules uniformly for all arches with "strip" command, so this commit alone doesn't solve mentioned problem but it opens a possibility to add later a patch to the kernel which will strip modules for ARC differently - and that's our plan for mainline kernel.

2016-08-28Revert "Added local directory as source of kernel code"Yann E. MORIN
This reverts commit 73da2ff6f718f2889e3c5024d899f8d58f502863. The reason for adding support for a local location was to be able to do development on the Linux kernel source tree on a local directory rather than have to clone it for every build. We already have a mechanism for that, it's called override-srcdir. It's been available since September 2011, more than a year before this patch was committed. Otherwise, we're going to be adding support for local sources in other packages. First was U-Boot as submitted by Adam. But what next? We can't have such support for all packages, especially since override-srcdir does the job. Besides, using a local source tree makes the build non-reproducible, so we don't really want to have this in a .config (or defconfig). We only handle the boolean option in legacy, as there is nothing we can do with the directory path. Signed-off-by: "Yann E.

2016-06-18linux: allow the selection of the architecture's default configurationThomas Petazzoni
To configure the Linux kernel, we currently provide two options: 1. Passing a defconfig name (for example "multi_v7"), to which we append "_defconfig" to run "make multi_v7_defconfig". 2. Passing a path to a custom configuration file. Unfortunately, those two possibilities do not allow to configure the kernel when you want to use the default configuration built into the kernel for a given architecture. For example, on ARM64, there is a single defconfig simply called "defconfig", which you can load by running "make defconfig". Using the mechanism (1) above doesn't work because we append "_defconfig" automatically. One solution would be to change (1) and require the user to enter the full defconfig named (i.e "multi_v7_defconfig" instead of "multi_v7"), but we would break all existing Buildroot configurations. So instead, we add a third option, which simply tells Buildroot to use the default configuration for the selected architecture. In this case, Buildroot will configure the kernel by running "make defconfig".

2016-05-31linux: provide symlink dtc->linux-dtc is there is no dtc yetThomas De Schampheleire
Commit ab74e09eb4e28dab8bed8d783c5f0464d39a32e7 renamed the dtc host tool provided by linux to linux-dtc to avoid clashes with the dtc host tool provided by host-dtc. However, external scripting may well rely on the existence of a device tree compiler as $(HOST_DIR)/usr/bin/dtc, regardless of its source. Changing these external scripts to use linux-dtc means that the scripts need to be aware of the buildroot release they are working with, which is not very nice. Add a symlink dtc->linux-dtc when no $(HOST_DIR)/usr/bin/dtc is present. When host-dtc is not enabled, the end result will be dtc and linux-dtc representing the same thing. When host-dtc is enabled, either it is build before linux and no symlink is created at any time, or it is build after linux, and the 'install' command in host-dtc will overwrite the symlink with a proper dtc. In both cases, the end result will be dtc and linux-dtc representing a different thing.

2016-02-10linux: add conditional patch for timeconst.plGustavo Zacarias
Kernels older than 3.9 (not counting stable releases) used the timeconst.pl perl script for their build process. The problem with this script is that it used deprecated perl features, namely defined(@array) which was removed for the perl 5.22 release, causing build failure of older kernels on newer distributions. To fix this instead of going the hard way (moving to the new timeconst.bc script) use the easy way by patching timeconst.pl with an upstream patch used for stable releases. First try a dry-run on the patch to see if it applies, if it does then call a proper APPLY_PATCHES to it. Tested against an arbitrary 2.6.30 kernel (applies and builds), against 4.4.1 for a missing timeconst.pl (does not apply since it's missing) and 3.8.13 (does not apply since it's fixed already).

2015-12-29linux: add blind kconfig option to require kernel modulesYann E. MORIN
Currently, packages that need the kernel to have support for laodable modules have two ways to require it: - either the use the kernel-module infra, which does it automatically, - or they do not use it, and they need to require it manually by setting the corresponding Makefile variable; however, they must only set it when they are actually enabled, which makes for a slightly cumbersome and ugly code, like: ifeq ($(BR2_PACKAGE_FOO),y) LINUX_NEEDS_MODULES = y endif Introduce a new blind Kconfig option that packages can select to signify they need kernel modules. That Kconfig option is then used to set the Makefile variable. It makes it cleaner: - code is simpler (one Kconfig line instead of a Makefile if-block, - this is handled at the Kconfig level, which is where we usually handle such dependencies.

2015-12-20linux: don't build appended DTB image in place and support multiple imagesThomas Petazzoni
Currently, the linux.mk logic for appended DTB image does the appending of the DTB in place, directly at the end of the zImage using a >> sign. This is incorrect because if you run "make linux-rebuild" multiple times, you get the DTB appended over and over again to the image. Since keeping the 'zImage' or 'uImage' name for the appended DTB image is not very clear, this commit moves to using the 'zImage.<dtb>' and 'uImage.<dtb>' format. This way, we can clearly distinguish the original image from the appended one. In addition, this naming scheme easily allows to generate *multiple* appended DTB images: from one zImage, you can generate multiple zImage.<dtb> for several DTBs, and then generate (if requested) the corresponding uImage.<dtb>. To achieve this, this commit: - Changes the definition of LINUX_APPENDED_DTB to iterate over $(KERNEL_DTS_NAME), and generate a zImage.<dtb> image for each of them. - Changes the addition of LINUX_APPENDED_DTB for appended uImage to also iterate over $(KERNEL_DTS_NAME). - Provide a different implementation of LINUX_INSTALL_IMAGE which installs all the appended DTB images (but not the bare image) - Remove the checks that verified that only one DT name is passed when appended DTB is used, since we now support generating multiple DT images. Some of the tested configuration: - Normal uImage with several DTBs BR2_LINUX_KERNEL_DEFCONFIG="mvebu_v7" BR2_LINUX_KERNEL_UIMAGE=y BR2_LINUX_KERNEL_UIMAGE_LOADADDR="0x200000" BR2_LINUX_KERNEL_DTS_SUPPORT=y BR2_LINUX_KERNEL_INTREE_DTS_NAME="armada-xp-matrix armada-xp-gp armada-370-mirabox" Contents of output/images/: armada-370-mirabox.dtb armada-xp-gp.dtb armada-xp-matrix.dtb uImage - Normal zImage with several DTBs BR2_LINUX_KERNEL_DEFCONFIG="mvebu_v7" BR2_LINUX_KERNEL_ZIMAGE=y BR2_LINUX_KERNEL_DTS_SUPPORT=y BR2_LINUX_KERNEL_INTREE_DTS_NAME="armada-xp-matrix armada-xp-gp armada-370-mirabox" Contents of output/images: armada-370-mirabox.dtb armada-xp-gp.dtb armada-xp-matrix.dtb zImage - Appended uImage with several DTBs: BR2_LINUX_KERNEL_DEFCONFIG="mvebu_v7" BR2_LINUX_KERNEL_APPENDED_UIMAGE=y BR2_LINUX_KERNEL_UIMAGE_LOADADDR="0x200000" BR2_LINUX_KERNEL_INTREE_DTS_NAME="armada-xp-matrix armada-xp-gp armada-370-mirabox" Contents of output/images: uImage.armada-370-mirabox uImage.armada-xp-gp uImage.armada-xp-matrix - Appended zImage with several DTBs: BR2_LINUX_KERNEL_DEFCONFIG="mvebu_v7" BR2_LINUX_KERNEL_APPENDED_ZIMAGE=y BR2_LINUX_KERNEL_INTREE_DTS_NAME="armada-xp-matrix armada-xp-gp armada-370-mirabox" Contents of output/images: zImage.armada-370-mirabox zImage.armada-xp-gp zImage.armada-xp-matrix In all configurations, the contents of output/target/boot/ was the same if BR2_LINUX_KERNEL_INSTALL_TARGET=y.

Currently, the only linux kernel tool packaged in Buildroot is perf and it's packaged as a separate generic package. This is a problem for licence information raised in this thread [1]. Since these tools require to build a Linux kernel, we can use some hooks in linux package like we did for linux extensions [2] and remove the perf package.

2015-07-14package/linux: check for config file before calling kconfig-packageYann E. MORIN
If we check that the user provides a config file after we call to the kconfig-package infra, the error message we get is the one for the kconfig-package infra, not the custom error message we want to show to the user. So, only call kconfig-package after we do the check. Move the check with the existing checks for the DTS, for consistency. [Thomas: put the checks together, but right before the kconfig-package call, rather than in the middle of the code, were the DTS related tests were located.] Signed-off-by: "Yann E.

2015-07-13linux: adjust fixup logic for ktapThomas Petazzoni
The ktap package requires some parts of the kernel tracing infrastructure to be enabled, especially CONFIG_EVENT_TRACING. However, this option is a blind option in the kernel, so enabling it in linux.mk has no effect: we need to enable a non-blind option that selects CONFIG_EVENT_TRACING. We've chosen to select CONFIG_ENABLE_DEFAULT_TRACERS. This fixes the build of ktap. [Thomas: use CONFIG_ENABLE_DEFAULT_TRACERS as suggested by Arnout.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Reviewed-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>

2015-05-02linux: do not check hashes for custom versions and tarballsYann E. MORIN
This one is a bit tricky, as the version can come from the linux-headers package, so we must also account for that. We currently have no hash file for linux, but better do the change now, which allows us to later add a hash file. Signed-off-by: "Yann E.

2015-04-09linux: simplify adding new extensionsYann E. MORIN
Curently, all three linux extensions follow the same layout: - test if the extension is enabled - add itself to linux' patch-dependencies - declare a macro, added as the pre-patch hook Except for the macro, all can be commonalised. Add a simple infrastructure for that: - extensions declare themselves in the list of extensions - extensions define their macro - the infra adds them to the patch-dependencies and pre-patch hooks as appropriate Signed-off-by: "Yann E.

2015-04-06packages: apply custom patches using *.patch instead of <pkg>-*.patchThomas Petazzoni
Several packages have some logic to apply custom patches that existed before the BR2_GLOBAL_PATCH_DIR mechanism: at91bootstrap, at91bootstrap3, barebox, uboot and linux. Currently, the logic of those packages to apply custom patches is to match <package-name>-*.patch, which is not consistent with what we've done for patches stored in the package directory, and for patches stored in BR2_GLOBAL_PATCH_DIR: in such cases, we simply apply *.patch. Therefore, for consistency reasons, this commit changes these packages to also apply *.patch. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Reviewed-by: "Yann E.

2015-03-30linux: use the package infrastructure to download patchesThomas Petazzoni
The linux package has a special handling of patches, with quite a bit of legacy in it. A problem caused by this special handling is that the linux package calls directly the DOWNLOAD_WGET macro, which means that the package infrastructure isn't aware of which patches get downloaded, and it prevents doing changes inside the package download infrastructure. This commit changes the handling of patches in the linux package in the following way: * The LINUX_PATCHES variable is kept as is: it lists all the patches mentioned in the Config.in option BR2_LINUX_KERNEL_PATCH. This option can contain http://, ftp://, https:// URLs, path to local files or local directories. This variable is *not* used by the generic package infrastructure, so it is purely internal to the Linux package. * The LINUX_PATCH variable is now filled in with the list of patches that should be downloaded. It is derived from LINUX_PATCHES by filtering the patches that have http://, ftp:// or https:// in their path. Since <pkg>_PATCH is handled by the package infrastructure, it means that those patches are now automatically downloaded and applied by the package infrastructure. * The LINUX_APPLY_PATCHES hook is renamed to LINUX_APPLY_LOCAL_PATCHES, because it is now only responsible of applying local patches: remote patches are handled by LINUX_PATCH. The implementation of the hook is changed to filter out the patches that have already taken care of by LINUX_PATCH, so that we only iterate through the list of local patches or local patch directories.

2015-03-04linux/linux.mk: custom dts path - build dtb only from *.dts filesIvo Slanina
When building device tree blobs from custom *.dts files, buildroot initializes KERNEL_DTS_NAME variable from all given file names. This causes that user can't provide one *.dts file and some other *.dtsi files as dependencies. Problem is fixed by adding filter for initializing KERNEL_DTS_NAME variable with *.dts files only. All user provided files are copied into kernel source tree, but only file names suffixed with *.dts are used for building appropriate *.dtb files.
