Create a dmabuf with libgbm

jkmi — Fri, 18 Jun 2021 07:35:58 GMT

Hello,

I'm using iMX8 mini and trying to figure out if it's possible to create dumb buffers via libgbm on that board.

I want to achieve the following -

1) open drm render node (not available on my board with vivante graphics. any ideas how to enable that?)

2) create gbm device

3) create gbm_bo

4) export handle

5) create image khr.

Is it possible to achieve that on imx8 provided it doesn't have drm render nodes?

Hello jkmi,

The i.mx8 does not provide renders node.and vivante is in binary form I don´t think it should be able to modify.

So is it possible to use drm on i.MX8 Plus?
