Tool/software: Linux

Hi,

Could anybody, please give idea about dri render128 node?

Although I had seen some article related with render node but all these articles is taking about off-screen rendering.

Actually, I want to render my display screen using render node without any master authentication and without depending on other application . So, is it possible?

Thanks & Regards

Mayur

    Although the render node for omapDRM is created by the driver, we do not support any render node specific functionality in /dev/dri/render128.

    If you just want to render, you do not need master authentication. You can use the GBM based EGL / GLES2 APIs to render into DRM GEM buffers. However, you will not be able to display the GEM buffers without being a DRM master.
