This is a list of things to be done for better devfs support in the
|
|
||||||
Linux kernel. If you'd like to contribute to the devfs, please have a
|
|
||||||
look at this list for anything that is unallocated. Also, if there are
|
|
||||||
items missing (surely), please contact me so I can add them to the
|
|
||||||
list (preferably with your name attached to them:-).

Device File System (devfs) Boot Options
|
|
||||||
|
|
||||||

|
||||||
|
|
||||||
When CONFIG_DEVFS_DEBUG is enabled, you can pass several boot options
|
|
||||||
to the kernel to debug devfs. The boot options are prefixed by
|
|
||||||
"devfs=", and are separated by commas. Spaces are not allowed. The
|
|
||||||
syntax looks like this:
|
|
||||||
|
|
||||||
devfs=<option1>,<option2>,<option3>
|
|
||||||
|
|
||||||
and so on. For example, if you wanted to turn on debugging for module
|
|
||||||
load requests and device registration, you would do:
|
|
||||||
|
|
||||||
devfs=dmod,dreg
|
|
||||||
|
|
||||||
You may prefix "no" to any option. This will invert the option.
|
|
||||||
|
|
||||||
|
|
||||||
Debugging Options
|
|
||||||
=================
|
|
||||||
|
|
||||||
These requires CONFIG_DEVFS_DEBUG to be enabled.
|
|
||||||
Note that all debugging options have 'd' as the first character. By
|
|
||||||
default all options are off. All debugging output is sent to the
|
|
||||||
kernel logs. The debugging options do not take effect until the devfs
|
|
||||||
version message appears (just prior to the root filesystem being
|
|
||||||
mounted).
|
|
||||||
|
|
||||||
These are the options:
|
|
||||||
|
|
||||||
dmod print module load requests to <request_module>
|
|
||||||
|
|
||||||
dreg print device register requests to <devfs_register>
|
|
||||||
|
|
||||||
dunreg print device unregister requests to <devfs_unregister>
|
|
||||||
|
|
||||||
dchange print device change requests to <devfs_set_flags>
|
|
||||||
|
|
||||||
dilookup print inode lookup requests
|
|
||||||
|
|
||||||
diget print VFS inode allocations
|
|
||||||
|
|
||||||
diunlink print inode unlinks
|
|
||||||
|
|
||||||
dichange print inode changes
|
|
||||||
|
|
||||||
dimknod print calls to mknod(2)
|
|
||||||
|
|
||||||
dall some debugging turned on
|
|
||||||
|
|
||||||
|
|
||||||
Other Options
|
|
||||||
=============
|
|
||||||
|
|
||||||
These control the default behaviour of devfs. The options are:
|
|
||||||
|
|
||||||
mount mount devfs onto /dev at boot time
|
|
||||||
|
|
||||||
only disable non-devfs device nodes for devfs-capable drivers
