The files in this directory describe the devices found in GXemul's "test 
machines". These machines do not match any real-world machines, but they 
have devices that are similar to those found in real machines:

  o)  console (dev_cons):
	A simple console device, with putchar() and getchar()
	functionality. It also has a halt() function, to make it easy
	to exit from the emulator.

  o)  mp (dev_mp):
	A multiprocessor inter-processor communication device.
	It also contains other useful functionality, such as retrieving
	the amount of "physical" RAM installed in the emulated machine.

  o)  framebuffer (dev_fb):
	640 x 480 pixels, 3 bytes per pixel, red-green-blue

  o)  disk (dev_disk):
	Used for reading and writing 512-byte sectors from/to disk images.

  o)  ethernet (dev_ether):
	A very simple ethernet NIC, capable of sending and receiving
	ethernet frames on the simulated network.

  o)  rtc (dev_rtc):
	A Real-Time Clock device. Used to retrieve the current time, and
	to cause periodic interrupts at a specific frequency.

These include files are not released under the same license as GXemul
itself. The include files are released as public domain, so they can be
reused also in projects that have BSD-incompatible licenses.

Please read the GXemul documentation for more details on how to use the
testmachine devices, and study the demo programs.
