/* The gradient pattern creates two horizontal gray gradients, split

* into two halves. The top half has 10bpc precision, the bottom half
|
|
* has 8bpc precision. When using with a 10bpc fb format, there are 3
|
|
* possible outcomes:
|
|
*
|
|
* - Pixel data is encoded as 8bpc to the display, no dithering. This
|
|
* would lead to the top and bottom halves looking identical.
|
|
*
|
|
* - Pixel data is encoded as 8bpc to the display, with dithering. This
|
|
* would lead to there being a visible difference between the two halves,
|
|
* but the top half would look a little speck-y due to the dithering.
|
|
*
|
|
* - Pixel data is encoded at 10bpc+ to the display (which implies
|
|
* the display is able to show this level of depth). This should
|
|
* lead to the top half being a very clean gradient, and visibly different
|
|
* from the bottom half.
|
|
*
|
|
* Once we support additional fb formats, this approach could be extended
|
|
* to distinguish even higher bpc precisions.
|
|
*
|
|
* Note that due to practical size considerations, for the screens
|
|
* where this matters, the pattern actually emits stripes 2-pixels
|
|
* wide for each gradient color. Otherwise the difference may be a bit
|
|
* hard to notice.
