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