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.

2010-12-17linux: add support for ELF vmlinux imageThomas Petazzoni

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.

2010-12-11linux: restore DEPMOD usageMike Frysinger
The linux.mk rewrite lost the DEPMOD setting while installing modules which means depending on host-module-init-tools has been useless. Instead, the build system has been executing /sbin/depmod. While we're here, drop the INSTALL_MOD_PATH since LINUX26_MAKE_FLAGS already contains it.

2010-12-11linux: set a few more initramfs opts for newer kernelsMike Frysinger

2010-09-15linux: don't force no initramfsThomas Petazzoni
When initramfs was not selected as a root filesystem, we forcefully disabled the initramfs in the kernel configuration. However, it prevents an user from manually managing its initramfs, as we override the option he has set in his kernel configuration file. There's no real reason to do so: when initramfs is not selected as the root filesystem, just don't touch initramfs related options in the kernel configuration.
