topic Combining planes via IPUv3 in i.MX Processors

Combining planes via IPUv3

Hello Everyone,

We have some problem using the gpu of our i.MX6Solo.

We want to combine 3-planes to a single LVDS display. One plane for the background, one big plane used for a scroll box and a cursor plane on top.

In the FTF-CON-F0119 “A Deep Dive into Image Processing for i.MX 6 Application Processors” document from Oliver Brown APR.10.2014 on page 58, there is a picture of the IPUv3 showing exactly that task.

Our program is using the framebuffer device. Without any window manager like X11 or something else.

We try to do that job by using the drm driver. But unfortunately I get an empty pointer when I call the drmModeResPtr drmModeGetResources(int fd) routine.

Are there some combining planes sources example available?

Thanks,

Heiner

Hi Heiner

for ipu combining examples one can look at
https://community.nxp.com/docs/DOC-94961

FTF-CON-F0119 is not applicable to gpu as ipu and gpu are different modules
with different capabilities, for gpu capabilities one can look at attached file and examples in Gpu Tools on
IDE - Debug, Compile and Build Tools (16)
