So, in my DRM case I would open the drm device and probe for the actual hardware and instanciate the corresponding winsys, eg. i915_drm_winsys. Then create a proper pipe for that device. Or just use the appropriate helpers in from drm-helper.h ? Is there some function that does all that, including the probing, together at once ?

By the way: what exactly does struct pipe_screen represent ? An pipe and screen (for certain hw) together ? Is that the centerpiece of all further operations, similar to cairo's cairo_device_t ? --mtx _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
