[PATCH] drm/etnaviv: init DMA ops for virtual master device

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



All the DRM GEM dma-buf import/export operations are done through the
virtual DRM master device. As this isn't instanciated from DT anymore
we need to make sure the DMA ops are set up correctly.
