* COMMENT: Various test machines |
31 |
* |
32 |
* Generally, the machines are as follows: |
33 |
* |
34 |
* bareXYZ: A bare machine using an XYZ processor. |
35 |
* |
36 |
* testXYZ: A machine with an XYZ processor, and some experimental |
37 |
* devices connected to it. |
38 |
* |
39 |
* The experimental devices in the test machines are: |
40 |
* |
41 |
* cons A serial I/O console device. |
42 |
* disk A device for reading/writing (emulated) disk sectors. |
43 |
* ether An ethernet device, for sending/receiving ethernet |
44 |
* frames on an emulated network. |
45 |
* fb Framebuffer (24-bit RGB per pixel). |
46 |
* irqc A generic interrupt controller. |
47 |
* mp A multiprocessor controller. |
48 |
* rtc A real-time clock device. |
