Hello everyone, The patches adds support for DMABUF [1] exporting to V4L2 stack. It was updated from [7] after Laurent Pinchart's review. The previous patchset was split into two parts. The support for DMABUF importing was posted in [2]. The exporter part is dependant on DMA mapping redesign [3] which is not merged into the mainline. Therefore it is posted as a separate patchset. This patchset is rebased on 3.4-rc1 plus the following patchsets: - support for DMABUF importing in V4L2 [2] - DMA mapping redesign [3] - support for dma_get_pages extension [4] - support for vmap extension to dmabuf framework by Dave Airlie [5][6] [1] https://lkml.org/lkml/2011/12/26/29 [2] http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/46586 [3] http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819 [4] http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/43793/focus=43803 [5] http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/46713 [6] http://cgit.freedesktop.org/~airlied/linux/commit/?h=drm-dmabuf2&id=c481a5451744fe3c4c950a446be10d3212d633d8 [7] http://thread.gmane.org/gmane.comp.video.dri.devel/66213 Marek Szyprowski (1): v4l: vb2-dma-contig: let mmap method to use dma_mmap_coherent call Tomasz Stanislawski (12): v4l: add buffer exporting via dmabuf v4l: vb2: add buffer exporting via dmabuf v4l: vb2-dma-contig: add setup of sglist for MMAP buffers v4l: vb2-dma-contig: add support for DMABUF exporting v4l: vb2-dma-contig: add vmap/kmap for dmabuf exporting v4l: vb2-dma-contig: change map/unmap behaviour for importers v4l: vb2-dma-contig: change map/unmap behaviour for exporters v4l: s5p-tv: mixer: support for dmabuf importing v4l: s5p-tv: mixer: support for dmabuf exporting v4l: fimc: support for dmabuf importing v4l: fimc: support for dmabuf exporting v4l: vivi: support for dmabuf exporting drivers/media/video/Kconfig | 1 + drivers/media/video/s5p-fimc/fimc-capture.c | 11 ++- drivers/media/video/s5p-tv/Kconfig | 1 + drivers/media/video/s5p-tv/mixer_video.c | 12 ++- drivers/media/video/v4l2-compat-ioctl32.c | 1 + drivers/media/video/v4l2-ioctl.c | 7 + drivers/media/video/videobuf2-core.c | 66 ++++++++ drivers/media/video/videobuf2-dma-contig.c | 224 +++++++++++++++++++++++++- drivers/media/video/vivi.c | 9 + include/linux/videodev2.h | 23 +++ include/media/v4l2-ioctl.h | 2 + include/media/videobuf2-core.h | 2 + 12 files changed, 348 insertions(+), 11 deletions(-) -- 1.7.5.4 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
