1.0	Overview

	This is the README file for the sample kld module
	that mimics a character device driver.

	A kld module may be used to load any data or
	program into the kernel that can be made available by
	modifying a table, pointer, or other kernel data to inform
	the kernel that the module should be used instead of the
	previous code/data path.

	Generally, it is assumed that a loadable module is one of
	a set of similar modules (such as a file system or console
	terminal emulation), and that the reference is through a
	table (such as vfssw[]), and that a "special" value is
	assigned to the slots which are allowed to be replaced.
	This is not enforced, so you may use the kld module 
	any way you see fit.

	As with the loadable system calls, it may be desirable to
	allow the module loader to replace an *existing* entry to
	try out changes to kernel code without rebuilding and
	booting from the new kernel.

	The idea behind this example is to show some interaction
	with the device driver. Therefore the flow of the code that
	this driver is aimed at is as follows:

	    open(2) -> ioctl(2) -> write(2) -> read(2) -> close(2).

	We will first open the device in the /dev/ directory; then
	we will send an ioctl message to it using ioctl(2) call;
	then write a small string via the write(2) call. This string
	we write to the device will be stored in a static buffer,
	and later will be accessible via the read(2) call. Finally,
	we will close(2) our open()'d device so that we may no
	longer make read or write calls on it.

2.0	Directions

	To test the module, do the following:

		cd module
		make load

	A load message (the copyright) will be printed on the console.

		cd ../test
		make load

	The system call prints a message on the console when called.
	This message will be printed when running "make load" in
	the "test" subdirectory.


3.0	Recovering resources

	The module consumes 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 miscellaneous module will be unloaded by name.

## SVN ## Remove duplicate const specifiers in many drivers (I hope I got all of
## SVN ## them, please let me know if not).  Most of these are of the form:
## SVN ##
## SVN ## static const struct bzzt_type {
## SVN ##       [...list of members...]
## SVN ## } const bzzt_devs[] = {
## SVN ##       [...list of initializers...]

## SVN ##
## SVN ## The second const is unnecessary, as arrays cannot be modified anyway,
## SVN ## and if the elements are const, the whole thing is const automatically
## SVN ## (e.g. it is placed in .rodata).
## SVN ##
## SVN ## I have verified this does not change the binary output of a full kernel

	The idea behind this example is to show some interaction
	with the device driver. Therefore the flow of the code that
	this driver is aimed at is as follows:

	    open(2) -> ioctl(2) -> write(2) -> read(2) -> close(2).

	We will first open the device in the /dev/ directory; then
	we will send an ioctl message to it using ioctl(2) call;
	then write a small string via the write(2) call. This string
	we write to the device will be stored in a static buffer,
	and later will be accessible via the read(2) call. Finally,
	we will close(2) our open()'d device so that we may no
	longer make read or write calls on it.
