1.0 Overview
|
|
|
|
|
|
|
|
|
|
This is the README file for the sample loaded file system.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
2.0 Preparation
|
|
|
|
|
|
|
|
|
|
To use this module, you must have a kernel the does *NOT*
|
|
|
|
|
have an existing "kernfs" file system in it. To determine
|
|
|
|
|
if your system has the "kernfs" file system in it, check
|
|
|
|
|
the build file for your kernel (usually this file is named
|
|
|
|
|
"/sys/i386/conf/GENERICISA") for the following:
|
|
|
|
|
|
|
|
|
|
options KERNFS
|
|
|
|
|
|
|
|
|
|
By default, NetBSD has this file system compiled as part
|
|
|
|
|
of the kernel; if you wish to use this example with NetBSD
|
|
|
|
|
you will have to remove this "options" line and rebuild
|
|
|
|
|
your kernel.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
3.0 Directions
|
|
|
|
|
|
|
|
|
|
To test the module, do the following:
|
|
|
|
|
|
|
|
|
|
cd module
|
|
|
|
|
make load
|
|
|
|
|
|
|
|
|
|
A load message (the copyright) will be printed on the console.
|
|
|
|
|
|
|
|
|
|
You must then add the following line to the "/etc/fstab" file:
|
|
|
|
|
|
|
|
|
|
kernfs /kern kernfs rw 1 1
|
|
|
|
|
|
|
|
|
|
At the root prompt, type the following:
|
|
|
|
|
|
|
|
|
|
mkdir /kern
|
|
|
|
|
|
|
|
|
|
Ignore the following error if it occurs:
|
|
|
|
|
|
|
|
|
|
mkdir: /kern: File exists
|
|
|
|
|
|
|
|
|
|
Again at the root prompt, type the following command:
|
|
|
|
|
|
|
|
|
|
mount /kern
|
|
|
|
|
cd /kern
|
|
|
|
|
cat version
|
|
|
|
|
|
|
|
|
|
This will verify that the module is working correctly.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
4.0 Recovering resources
|
|
|
|
|
|
|
|
|
|
The file system consumes 8 pages of memory when loaded; it
|
|
|
|
|
can be freed up by unloading it. To unload it, type the
|
|
|
|
|
following from the directory this file is in:
|
|
|
|
|
|
|
|
|
|
cd module
|
|
|
|
|
make unload
|
|
|
|
|
|
|
|
|
|
The file system will be unloaded by name.
|
