[PATCH v4 00/14] Integration of videobuf2 with dmabuf

Hello everyone, This patchset adds support for DMABUF [2] importing to V4L2 stack. The support for DMABUF exporting was moved to separate patchset due to dependency on patches for DMA mapping redesign by Marek Szyprowski [4]. v4: - rebased on mainline 3.4-rc2 - included missing importing support

[PATCH v4 03/14] v4l: vb2: add support for shared buffer (dma_buf)

From: Sumit Semwal sumit.sem...@ti.com This patch adds support for DMABUF memory type in videobuf2. It calls relevant APIs of dma_buf for v4l reqbuf / qbuf / dqbuf operations. For this version, the support is for videobuf2 as a user of the shared buffer; so the allocation of the buffer is done

[PATCH v4 06/14] v4l: vb2-dma-contig: Remove unneeded allocation context structure

vb2-dma-contig returns a vb2_dc_conf structure instance as the vb2 allocation context. That structure only stores a pointer to the physical device. Remove it and use the device pointer directly as the allocation context. Signed-off-by: Tomasz Stanislawski t.stanisl...@samsung.com ---

[PATCH v4 12/14] v4l: vb2-dma-contig: change map/unmap behaviour for importers

The DMABUF documentation says that the map_dma_buf callback should return scatterlist that is mapped into a caller's address space. In practice, almost none of existing implementations of DMABUF exporter does it. This patch breaks the DMABUF specification in order to allow exchange DMABUF buffers
