Code Activity

add my 2.6.15-rc5 port (yay) with devfs. The PCI subsystem is broken on Broadcom boards, we are working on it. Also upgrade iptables to 1.3.4

help
Exports the dump image of crashed kernel in ELF format.
+config DEVFS_FS
+ bool "/dev file system support (OBSOLETE)"
+ depends on EXPERIMENTAL
+ help
+ This is support for devfs, a virtual file system (like /proc) which
+ provides the file system interface to device drivers, normally found
+ in /dev. Devfs does not depend on major and minor number
+ allocations. Device drivers register entries in /dev which then
+ appear automatically, which means that the system administrator does
+ not have to create character and block special device files in the
+ /dev directory using the mknod command (or MAKEDEV script) anymore.
+
+ This is work in progress. If you want to use this, you *must* read
+ the material in <file:Documentation/filesystems/devfs/>, especially
+ the file README there.
+
+ Note that devfs no longer manages /dev/pts! If you are using UNIX98
+ ptys, you will also need to mount the /dev/pts filesystem (devpts).
+
+ Note that devfs has been obsoleted by udev,
+ <http://www.kernel.org/pub/linux/utils/kernel/hotplug/>.
+ It has been stripped down to a bare minimum and is only provided for
+ legacy installations that use its naming scheme which is
+ unfortunately different from the names normal Linux installations
+ use.
+
+ If unsure, say N.
+
+config DEVFS_MOUNT
+ bool "Automatically mount at boot"
+ depends on DEVFS_FS
+ help
+ This option appears if you have CONFIG_DEVFS_FS enabled. Setting
+ this to 'Y' will make the kernel automatically mount devfs onto /dev
+ when the system is booted, before the init thread is started.
+ You can override this with the "devfs=nomount" boot option.
+
+ If unsure, say N.
+
+config DEVFS_DEBUG
+ bool "Debug devfs"
+ depends on DEVFS_FS
+ help
+ If you say Y here, then the /dev file system code will generate
+ debugging messages. See the file
+ <file:Documentation/filesystems/devfs/boot-options> for more
+ details.
+
+ If unsure, say N.
+
config SYSFS
bool "sysfs file system support" if EMBEDDED
default y
