[Mesa-dev] [PATCH 1/9] gallium/dri: Support DRI Image extension version 6

This part doesn't work.
A dri_context can be converted to a st_context.

To get the pipe_resource, we should use the st_context_iface in dri_context, and the function get_resource_for_egl_image.

Unfortunately, this function isn't implemented in mesa.

I've found this three years old patch, which implements it: http://marc.info/?l=mesa3d-dev&m=128431813411436
The get_resource_for_egl_image we need is at the end of the patch, and the implementation look correct to me.

Could a state_tracker expert review it and push the part of the patch we need?

>+   img->dri_format = driGLFormatToImageFormat(obj->_BufferObjectFormat);

This part doesn't work either: it doesn't give the correct format.


Getting this function right would really help to write glamor dri3 helpers
