    Get GPU total memory in OpenGL under Linux


      Hi guys,


      I'm going back to OpenGL for some demo project.

      I simply want to know the total amount of memory of the GPU using OpenGL.


      I get this sample code :



      UINT n = wglGetGPUIDsAMD(0, 0);
      UINT *ids = new UINT[n];
      size_t total_mem_mb = 0;
      wglGetGPUIDsAMD(n, ids);


      But it required wglext.h which is Microsoft only plateform.

      I don't find anything like this in glxext.h for Linux. Did I miss something?

      And for compatibility, if you have also infos for OSX.


      N.B.: I already get the available RAM for GPU with TEXTURE_FREE_MEMORY_ATI but I would like to know the percentage of RAM consumed.


      Best regards
