From b22e6690a3f656e3adb821ab4859e02932048066 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 14 Dec 2015 22:39:44 +0200 Subject: drm/omap: gem: Implement dma_buf import OMAP GEM objects backed by dma_buf reuse the current OMAP GEM object support as much as possible. If the imported buffer is physically contiguous its physical address will be used directly, reusing the OMAP_BO_MEM_DMA_API code paths. Otherwise it will be mapped through the TILER using a pages list created from the scatterlist instead of the shmem backing storage.
