Subject: [media] v4l: ti-vpe: Allow DMABUF buffer type support Author: Archit Taneja <[email protected]> Date: Thu Mar 13 08:44:06 2014 -0300 For OMAP and DRA7x, we generally allocate video and graphics buffers through omapdrm since the corresponding omap-gem driver provides DMM-Tiler backed contiguous buffers. omapdrm is a dma-buf exporter. These buffers are used by other drivers in the video pipeline. Add VB2_DMABUF flag to the io_modes of the vb2 output and capture queues. This allows the driver to import dma shared buffers.
