obj->base.dma_buf represents a dma-buf exported from this object (for use by others). On the contrary, obj->base.import_attach represents the source dma-buf that was used to create this object (if any). When serialising with third parties, we need to wait on their rendering via the import attachment as well as their rendering on our exported dma-buf. v2: Wait on both import and export. v3: Rebase Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Alex Goins <agoins@nvidia.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Tested-by: Alex Goins <agoins@nvidia.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1466148527-10891-1-git-send-email-chris@chris-wilson.co.uk
