initramfs/init: make sure that 0, 1, 2 fds are available

2011-08-04T19:52:21+00:00

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. Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

System config: split static-dev device table setting into seperate option

2011-07-24T22:09:33+00:00

As discussed here: http://lists.busybox.net/pipermail/buildroot/2011-May/043251.html Add BR2_ROOTFS_STATIC_DEVICE_TABLE for the extra device table file(s) to create device nodes in /dev, rather than complicated logic in BR2_ROOTFS_DEVICE_TABLE, making it complicated to move between static and dynamic modes.

initramfs: fix boot with dynamic /dev

2011-07-20T14:30:14+00:00

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 Signed-off-by: Peter Korsgaard

sh: Fix Buildroot sh targets to match gnuconfig targets

2011-07-18T21:26:12+00:00

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. Signed-off-by: Phil Edworthy Acked-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

Rework the logging daemons startup

2011-07-04T18:57:10+00:00

The logging mechanism startup being in inittab, it isn't easy to overcharge the default policy. With this patch, the startup of the syslog daemon is moved to an init.d script, that can easily be overwritten. [Peter: use install -D] Signed-off-by: Maxime Ripard Signed-off-by: Peter Korsgaard

Create and mount /dev/shm

The /dev/shm directory is neither created nor mounted as tmpfs as boot time. This will cause troubles when using named semaphores on the system. Signed-off-by: Maxime Ripard Signed-off-by: Peter Korsgaard
