2011-11-14linux: make vmlinux target available to all architecturesThomas De Schampheleire
The 'vmlinux' target in the linux build directory is a generic target. It may not be directly bootable for all architectures, but for projects where a custom bootloader is used, it can be of value. Previously, this target was only available for mips architectures. This patch removes this restriction.

2011-11-11linux: add linux-update-config and linux-update-defconfig targetsThomas De Schampheleire
In analogy to build targets uclibc-update and busybox-update, add extra targets to copy the current configuration to the custom configuration file set in buildroot. These targets facilitate the work of developers adding support for a specific board. linux-update-config copies .config directly. linux-update-defconfig first creates a defconfig and copies that.

2011-09-29package: remove useless arguments from GENTARGETSThomas Petazzoni
Thanks to the pkgparentdir and pkgname functions, we can rewrite the GENTARGETS macro in a way that avoids the need for each package to repeat its name and the directory in which it is present.

2011-09-27fs/initramfs: refactor with fs/cpioArnout Vandecappelle (Essensium/Mind)
An initramfs is in fact the same as a cpio archive, but embedded in the kernel. So instead of duplicating the cpio infrastructure, we can simply build images/rootfs.cpio and link that into the kernel.

2011-09-20rtai, xenomai: use the pre patch hook pointThomas Petazzoni
The post extract hook point is not really correct as what RTAI and Xenomai extensions are doing is patching the kernel. The post patch hook point doesn't work, because RTAI and Xenomai patches would be applied *after* all other patches, while it sounds more logical to apply them first, and *then* allow the user to apply some platform/board specific patches if needed.

2011-09-18Add xenomai real-time Framework to buildrootThomas De Schampheleire
[Fixes by Thomas, including comments from Arnout: * Use AUTOTARGETS instead of GENTARGETS * Use $(KERNEL_ARCH) instead of $(BR2_ARCH) as argument to the prepare-kernel.sh script. This allows the arch name to be fixed with the usual sed expressions and the quotes to be stripped. * Add the --verbose option to prepare-kernel.sh. This allows to get some clear error message when no Xenomai patch has been found for the current kernel version. * Improve the help texts as suggested by Arnout, and remove the now useless README file. * Add a BR2_PACKAGE_XENOMAI_SMP option, instead of poking inside the kernel configuration to find out whether SMP is enabled or not. This cannot work because: 1) the kernel might be built outside of Buildroot and 2) if the kernel is built inside Buildroot, it is built *after* Xenomai, so the kernel configuration file is typically not yet present. * Simplify the ARM subarchitecture selection as suggested by Arnout. * Remove the documentation and development files according to Buildroot standards (using BR2_HAVE_DOCUMENTATION and BR2_HAVE_DEVFILES). * Simplify the /etc/ld.so.conf modification logic. ] [Peter: whitespace fixes] Signed-off-by: Benoit Mauduit <benoit.mauduit@openwide.fr> Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2011-07-11linux: add support for 3.x and -rc versionsThomas Petazzoni
The assumption that all kernels are in http://www.kernel.org/pub/linux/kernel/v2.6/ is no longer true: versions 3.x are in separate directories. We now compute the directory name from the major and minor versions of the version provided by the user. This assumes that the 3.1 version will be in a /v3.1/ directory, which we don't know yet because the 3.1 cycle hasn't started yet. At the same time, we add support for the official -rcX versions. Patch tested by compiling 3.0-rc6, which Buildroot has successfully downloaded and built.

2011-07-11Improve TARGETS handling for bootloaders and kernelThomas Petazzoni
As the kernel and bootloaders do not use the normal BR2_PACKAGE_* Kconfig options, their target name was not automatically added to the global TARGETS variable. Each bootloader .mk and the linux.mk had to add their own target manually to TARGETS, and the package infrastructure was making tests on non-existing Kconfig variables. This commit improves the package infrastructure so that it looks at BR2_PACKAGE_<pkg> for packages, BR2_TARGET_<pkg> for bootloaders and at the special BR2_LINUX_KERNEL for the linux package. This allows to simplify a little bit the bootloaders and linux .mk files. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2011-05-09Create menu entry to select device creation methodYegor Yefremov
Four methods for the creation of device files in /dev are now proposed: - static method uses device table as before - devtmpfs method enables this feature in kernel - mdev method adds mdev starting script to the file system and selects mdev itself for installation - udev method selects udev for installation All dynamic methods are based on devtmpfs, so one doesn't need to care about /dev folder.

2010-12-22linux: don't force IPv6 configuration in kernelThomas Petazzoni
As per the discussion at http://lists.busybox.net/pipermail/buildroot/2010-December/040030.html, remove the bits that forced the IPv6 configuration in the kernel depending on the toolchain ability to support (or not) IPv6. You may have a toolchain with IPv6 support but still don't want to have IPv6 in your kernel. The only parameters we adjust in the kernel configuration are: * ARM EABI, since we got a lot of bug reports regarding misconfigured kernel compared to the ABI used by userspace applications. * initramfs, since its contents are generated by Buildroot itself Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2010-12-17linux: add KERNEL_ARCH_PATH to fix x86-specific issueThomas Petazzoni
Both i386 and x86_64 architectures are supported by the arch/x86 directory in the kernel. So, when we copy the kernel configuration file to arch/$(KERNEL_ARCH)/configs/, it does not work because arch/i386 and arch/x86_64 do not exist. So, we introduce KERNEL_ARCH_PATH, which is the path to the architecture specific directory in the kernel source tree.

2010-12-16linux: support a space-separated list of patchesThomas Petazzoni
The kernel being a component that often needs a fairly important set of changes to be adapted to a particular hardware platform, having maximum flexibility on the patching process is a nice thing. Therefore, as per the discussions from the Buildroot Developer Day, we add a mechanism to apply a list of patches (that could come either from URLs, local files or local directories).

2010-12-16linux: Import minimal defconfigs as defconfigsThomas Petazzoni
Now that minimal kernel defconfigs are used in Buildroot, the problem is that copying those minimal configuration files to .config in the kernel source tree does not work, as kconfig will ask interactively what should be the value for all unspecified options. On suggestion on Sam Ravnborg, the easiest way to solve this is to import the minimal defconfig file as a defconfig inside the kernel tree (in arch/$(ARCH)/configs) and configure the kernel with it.
