I am working on a board based on imx53. What I am doing is to support xrandr dual display on it. Clone mode works well. But when it comes to extend mode, there is something strange as the picture shows.
extend mode: hdmi + lvds
pos: hdmi right-of lvds
1. If the summary of the width of the two outputs is larger than 2048, the display appears abnormal.
If EXA is disabled, dual display works well. Does anyone have met something similar before?
2. In Z160.h:
/* Largest buffer is 2048x2048 */
#define Z160_MAX_WIDTH 2048
#define Z160_MAX_HEIGHT 2048
Does gpu z160 support a buffer larger than 2048x2048 ?
Any advice is appreciated.
Thank you in advance.
