Overlay support in iMX6D/6Q

[VishalMore]

Dear TI team,

Our usecase is to show overlay window on top of primary window using source color keying mechanism. I understand that IPU->DP module in iMX6D/6Q supports overlay management using source transparent color keying and this IPU->DP hardware is exposed to userspace using libdrm API which is included in iMX6D/6Q Linux image.

Will you help with libdrm APIs to achieve below functionality.

1. How to set overlay plane?

2. How to set z-order of overlay plane?

3. How to set source transparent color?

4, How to control brightness and contrast of display port?

Any demonstration source code for above functionality using libdrm APIs e.g. modetest utility will be helpful.

Thanks.
