* Create and mount /dev/shmMaxime Ripard2011-07-032-0/+2
| | | | | | | | | 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 <maxime.ripard@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* Move rootfs content options under system configurationPeter Korsgaard2011-05-121-76/+1
| | | | | | | | | Instead of the current mix between system config and filesystem menus. At the same time rename 'Target filesystem options' menu to 'Filesystem images' as it now only contains options about image formats. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* target/generic: only show getty port option if default skeleton is usedPeter Korsgaard2011-05-121-4/+0
| | | | | | | | The special marker in etc/inittab might not be present with a custom skeleton. At the same time make the option always active, remove the hardcoded tty1/tty2 gettys and reword the option description slightly. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* Allow several device tables and split in two parts our device tableThomas Petazzoni2011-05-092-10/+20
| | | | | | | | | | | | | | 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. We take this opportunity to move the documentation of the device table format in a common location, package/makedevs/README.

* Create menu entry to select device creation methodYegor Yefremov2011-05-091-6/+27
| | | | | | | | | | | | | | | | | | 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.

* fs/ext2: remove redundant BR2_TARGET_ROOTFS_EXT2_SQUASH optionPeter Korsgaard2011-01-142-9/+0
| | | | | | | The generic fs handling does a chmod -R 0:0 $(TARGET_DIR), so there's no need for a specific option to enforce this when making an ext2fs image. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* genext2fs.sh: improve number of blocks calculationPeter Korsgaard2010-12-301-14/+11
| | | | | | | | | | | | | Closes #2929 Instead of just adding a fixed amount to the blocks used, try to estimate the real space needed according to the filesystem structure (bitmaps, inodes, blocks). The side effect of this is that we no longer significantly overestimate the size needed for small file systems. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

| | | | | | | | | | | | Those folders are currently created using makedevs according to the specifications in device_table.txt. However, as makedevs is no longer executed when dynamic device creation methods are selected (devtmpfs, udev, mdev), those folders must be created differently.

| | | | | | | | | | | | | This used to be needed when the filesystem code was rewritten, but not the Linux compilation code. Now that the Linux compilation code has been rewritten, the mechanism to ensure that initramfs gets built *before* the kernel so that it can be integrated is different, and this INITRAMFS_TARGET variable is no longer 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.

* jffs2: let makedevs create device filesThomas Petazzoni2010-06-051-4/+0
| | | | | | | | | | | | | | | | | | | | | | The common filesystem infrastructure in fs/common.mk uses a smart combination of makedevs and fakeroot to create the device files in the target filesystem images without being root. This technique is applied to all filesystem formats that rely on this common infrastructure, and JFFS2 is one of them. Therefore, using the -D option of mkfs.jffs2, which allows to specify a device table, is redundant with the usage of makedevs. And it is worst than redundant: for some reason, -D does not create all device files with the correct major and minor numbers, as reported in bug #1771. For coherence, we just remove the usage of mkfs.jffs2 -D option, and rely on makedevs/fakeroot to create the device files. This commit fixes bug #1771.
