* fs/initramfs: refactor with fs/cpioArnout Vandecappelle (Essensium/Mind)2011-09-274-240/+18
| | | | | | | | | | 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.

* cpio: fix boot with dynamic /devArnout Vandecappelle (Essensium/Mind)2011-09-272-5/+26
| | | | | | | | | | | | Devtmpfs doesn't get automounted by the kernel when an initramfs is used. Since cpio archives are used almost exclusively as an initramfs, the same fix should be applied to it as for the initramfs. Cfr. commit 424888e47431db738f5f9b3c6392435bfce7a842 and 10a130f91e5b947e2d2558443ff09b1686eac273.

* initramfs/init: make sure that 0, 1, 2 fds are availableThomas Petazzoni2011-08-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | As the kernel doesn't automatically mount devtmpfs when an initramfs is used, commit 424888e47431db738f5f9b3c6392435bfce7a842 has introduced a small wrapper script that mounts devtmpfs before starting the real init. Unfortunately, the problem is that in this case, the init process runs without any 0, 1 and 2 file descriptors, so none of the messages/errors printed by the various initialization scripts can be seen. This is due to the fact the init process relies on 0, 1 and 2 being opened by the kernel before init is started. However, as /dev/console isn't present on the filesystem at the time the kernel tries to open the console to create the 0, 1 and 2 file descriptors, the kernel fails on this and prints the famous "Warning: unable to open an initial console". The proposed workaround is to actually open 0, 1 and 2 to /dev/console in the wrapper script, right after mounting the devtmpfs filesystem, and before starting the real init. The "Warning" from the kernel is still shown, but at least the messages from the init scripts are visible.

* initramfs: fix boot with dynamic /devPeter Korsgaard2011-07-202-2/+19
| | | | | | | | | | | Devtmpfs (which is used by devtmpfs/mdev/udev options) doesn't get automounted by the kernel when an initramfs is used, causing boot failures when a dynamic /dev is used. Fix it by adding a pre-init script to mount devtmpfs before running init. Reported-by: Arnout Vandecappelle <arnout@mind.be> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* sh: Fix Buildroot sh targets to match gnuconfig targetsPhil Edworthy2011-07-181-2/+2
| | | | | | | | | | | | | | sh2eb and sh2a_nofpueb gnuconfig targets are no longer supported in Buildroot. This patch replaces these Buildroot targets with sh2 and sh2a respectively, and adds sh4a targets as these are widely used. To build for devices without an fpu, the relevant toolchain flags will have to be specified.

| | | | | | | | | | | | | | This allows to have a device table for all directories/files and another device table for the device files themselves. Both are needed for static /dev, but only the first one is needed when devtmpfs/mdev/udev are used.

* linux: add support for initramfsThomas Petazzoni2010-06-222-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Buildroot, the kernel is built and installed *before* the root filesystems are built. This allows the root filesystem to correctly contain the kernel modules that have been installed. However, in the initramfs case, the root filesystem is part of the kernel. Therefore, the kernel should be built *after* the root filesystem (which, in the initramfs case simply builds a text file listing all files/directories/devices/symlinks that should be part of the initramfs). However, this isn't possible as the initramfs text file would lack all kernel modules. So, the solution choosen here is to keep the normal order: kernel is built before the root filesystem is generated, and to add a little quirk to retrigger a kernel compilation after the root filesystem generation. To do so, we add a ROOTFS_$(FSTYPE)_POST_TARGETS variable to the fs/common.mk infrastructure. This allows individual filesystems to set a target name that we should depend on *after* generating the root filesystem itself (contrary to normal ROOTFS_$(FSTYPE)_DEPENDENCIES, on which we depend *before* generating the root filesystem). The initramfs code in fs/initramfs/initramfs.mk uses this to add a dependency on 'linux26-rebuild-with-initramfs'. In linux/linux.mk, we do various things : * If BR2_TARGET_ROOTFS_INITRAMFS is enabled (i.e if initramfs is enabled as a root filesystem type), then we create an empty rootfs.initramfs file (remember that at this point, the root filesystem hasn't been generated) and we adjust the kernel configuration to include an initramfs. Of course, in the initial kernel build, this initramfs will be empty. * In the linux26-rebuild-with-initramfs target, we retrigger a compilation of the kernel image, after removing the initramfs in the kernel sources to make sure it gets properly rebuilt (we've experienced cases were modifying the rootfs.initramfs file wouldn't retrigger the generation of the initramfs at the kernel level). This is fairly quirky, but initramfs really is a special case, so in one way or another, we need a little quirk to solve its specialness.
