Support of 'desktop' OpenGL in 1.1.0 release of vivante gpu libraries

[sergeymatyukevi]

Hello,

Various marketing materials from Freescale and Vivante tell us that GC2000/GC2100 GPU provides support for 'desktop' OpenGL 2.1/3.0. On the other hand, all practical sources of information (including tutorials from Freescale FAE) are focused on OpenGL ES and OpenCL only. Latest release (v1.1.0) from Freescale with binary libraries from vivante contains only libGL.so.1.2 library (all the other libs are about OpenGL ES and OpenCL).

Questions:

- What is the reality of 'desktop' OpenGL support on GC2000/GC2100 ?  In particular, is there support for any version of 'desktop' GLSL ?

- What exactly is libGL.so.1.2 ?

Thanks,

Sergey

UPD. Looks like the answer: here is the information provided by glxinfo for libGL.so.1.2 :

OpenGL vendor string: Vivante Corporation

OpenGL renderer string: GC2000 Graphics Engine

OpenGL version string: 2.1 2.0.1

OpenGL shading language version string: 1.20

Hi

  I run glxinfo but it provided the information of mesa GL, I've already installed the gpu-viv-bin-imx6q and have relink the libGL.so.1 , why ?

Hi, I have a similar problem, below is glxinfo:

how to enable direct rendering? and how to use opengl of vivante? i have installed XXX.deb as i.MX_6_Series_Ubuntu_Multimedia_User's_Guide.pdf said. thanks!

Hi yuan:

     I still haven't find a solution, but I do get VIVANTE GC2000 in linaro, my problem is in debian 7.1. When change to linaro provided by Freescale, glxinfo works well and glxgears shows a FPS higher than glxgears with Mesa OpenGL in debian 7.1.

     I also find that when apt-get mesa-utils, in linaro it installs mesa-glu, but in debian it installs mesa-gl mesa-glu and maybe glew. And glx is GL+X, it also may caused by X version.

Thanks Wang, i am using in ubuntu11.10, i think i haven't started video driver of vivante, although i have installed vivante driver. i want to add vivante device in /etc/X11/xorg.conf file, but can't find the file,only find /usr/share/X11/xorg.conf.d/

how to start vivante device and use vivante driver?
