eca-lkm
=======
eca-lkm is a Linux kernel module (LKM) that provides a pseudo-random number
generator (PRNG) based on an elementary cellular automaton (ECA) that
follows Wolfram's Rule 30.
Installation
------------
Building a kernel module requires properly configures kernel source and headers.
To compile eca-lkm from source code:
$ make
To install the newly-built module into the module tree (will need root privileges, e.g. with 'sudo -E'):
$ make modules_install
To load the installed module:
$ modprobe eca30
or, alternatively, to load it from the source tree:
$ insmod eca30.ko
This will create a new character device, /dev/eca30.
udev
----
To have a device with proper attributes created under /dev when your module
is loaded, copy the file named 99-eca30.rules to /etc/udev/rules.d
$ mkdir -p /etc/udev/rules.d
$ cp 99-eca30.rules /etc/udev/rules.d
dkms
----
To have your module automatically rebuilt with every kernel update, you can
install DKMS and use it to manage your module.
Under /usr/src create a directory named eca30-0.0.1 and copy the source files
into it. Then install the module:
$ dkms install -m eca30 -v 0.0.1
Usage
-----
Reading from /dev/eca30 produces random numbers. Writing to /dev/eca30 changes
the internal state of ECA ("random pool").
