			graesslinUnsubmitted Not Done maybe ifdef the complete DrmSurfaceBuffer based on HAVE_GBM? Might simplify the ifdef logic in other areas. Or: move the DrmSurfaceBuffer into a dedicated .h and .cpp file and only include the .cpp if we have gbm. Then we don't need any ifdefs at all. graesslin: maybe ifdef the complete DrmSurfaceBuffer based on HAVE_GBM? Might simplify the ifdef logic in…
