| 28 | * This fairly simple test program dumps output in a similar format to the | ||
| 29 | * "xrandr" tool everyone knows & loves. It's necessarily slightly different | ||
| 30 | * since the kernel separates outputs into encoder and connector structures, | ||
| 31 | * each with their own unique ID. The program also allows test testing of the | ||
| 32 | * memory management and mode setting APIs by allowing the user to specify a | ||
| 33 | * connector and mode to use for mode setting. If all works as expected, a | ||
| 34 | * blue background should be painted on the monitor attached to the specified | ||
| 35 | * connector after the selected mode is set. | ||
| 36 | * | ||
| 37 | * TODO: use cairo to write the mode info on the selected output once | ||
| 38 | * the mode has been programmed, along with possible test patterns. | ||
