ximage_display_get_param() returns FALSE for NATIVE_PARAM_USE_NATIVE_BUFFER:
static int
ximage_display_get_param(struct native_display *ndpy,
                         enum native_param_type param)
{
   int val;

   switch (param) {
   case NATIVE_PARAM_USE_NATIVE_BUFFER:
      /* private buffers are allocated */
      val = FALSE;
      break;
   default:
      val = 0;
      break;
   }

   return val;
}

Yes, a software driver does not support EGL_KHR_image_pixmap.  With XGetImage and some efforts, it may be possible to support the extension.

Hi,

I am interested in getting this EGL extension supported on the client side. I'm playing with Mer/Nemo inside a Virtualbox image and it looks like I need this for getting the compositor to work properly, because the UI is currently broken without it.

So I would like to implement support for it, but I am completely new to Mesa or X11 development(I know a bit of C, though) so I have no idea how to start. Can you provide me any documentation, hints or examples on how I could get this implemented? Any help would be appreciated.

Thanks,
Cristian

The gallium EGL state tracker was removed with the following commit. Closing.

    st/egl: Remove.
    
    Largely superseeded by src/egl, and
    WGL/GLX_EXT_create_context_es_profile extensions.
    
    Note this will break Android.mk with gallium drivers -- somebody
    familiar with that build infrastructure will need to update it to use
    gallium drivers through egl_dri2.
    
    v2: Remove the _EGL_BUILT_IN_DRIVER_GALLIUM define from
    src/egl/main/Android.mk; and update the src/egl/main/Sconscript to
    create a SharedLibrary, add versioning, create symlink - copy the bits
    from egl-static, per Emil Velikov.

    v3: Disallow undefined symbols in libEGL.so.  Update release notes
