The latest support for DMABUF importing was posted in [1]. The exporter part is dependant on DMA mapping redesign [2] which is not merged into the mainline. Therefore it is posted as a separate patchset. Moreover some patches depends on vmap extension for DMABUF by Dave Airlie [3] and sg_alloc_table_from_pages function [4]. </blockquote><div> </div><div>Do you have your own git ?</div><div> </div><div>Thanks</div><div>Sangwook</div><div> </div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> Changelog: v0: (RFC) - updated setup of VIDIOC_EXPBUF ioctl - doc updates - introduced workaround to avoid using dma_get_pages, - removed caching of exported dmabuf to avoid existence of circular reference between dmabuf and vb2_dc_buf or resource leakage - removed all 'change behaviour' patches - inital support for exporting in s5p-mfs driver - removal of vb2_mmap_pfn_range that is no longer used - use sg_alloc_table_from_pages instead of creating sglist in vb2_dc code - move attachment allocation to exporter's attach callback [1] <a href="http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/48730" target="_blank">http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/48730</a> [2] <a href="http://thread.gmane.org/gmane.linux.kernel.cross-arch/14098" target="_blank">http://thread.gmane.org/gmane.linux.kernel.cross-arch/14098</a> [3] <a href="http://permalink.gmane.org/gmane.comp.video.dri.devel/69302" target="_blank">http://permalink.gmane.org/gmane.comp.video.dri.devel/69302</a> [4] This patchset is rebased on 3.4-rc1 plus the following patchsets: Marek Szyprowski (1): v4l: vb2-dma-contig: let mmap method to use dma_mmap_coherent call Tomasz Stanislawski (11): 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: s5p-fimc: support for dmabuf exporting v4l: s5p-tv: mixer: support for dmabuf exporting v4l: s5p-mfc: support for dmabuf exporting v4l: vb2: remove vb2_mmap_pfn_range function v4l: vb2-dma-contig: use sg_alloc_table_from_pages function v4l: vb2-dma-contig: Move allocation of dbuf attachment to attach cb drivers/media/video/s5p-fimc/fimc-capture.c | 9 + drivers/media/video/s5p-mfc/s5p_mfc_dec.c | 13 ++ drivers/media/video/s5p-mfc/s5p_mfc_enc.c | 13 ++ drivers/media/video/s5p-tv/mixer_video.c | 10 + drivers/media/video/v4l2-compat-ioctl32.c | 1 + drivers/media/video/v4l2-dev.c | 1 + drivers/media/video/v4l2-ioctl.c | 6 + drivers/media/video/videobuf2-core.c | 67 ++++++ drivers/media/video/videobuf2-dma-contig.c | 323 ++++++++++++++++++++++----- drivers/media/video/videobuf2-memops.c | 40 ---- include/linux/videodev2.h | 26 +++ include/media/v4l2-ioctl.h | 2 + include/media/videobuf2-core.h | 2 + include/media/videobuf2-memops.h | 5 - 14 files changed, 411 insertions(+), 107 deletions(-) -- 1.7.9.5 _______________________________________________ Linaro-mm-sig mailing list <a href="mailto:Linaro-mm-sig@lists.linaro.org" target="_blank">Linaro-mm-sig@lists.linaro.org</a> <a href="http://lists.linaro.org/mailman/listinfo/linaro-mm-sig" target="_blank">http://lists.linaro.org/mailman/listinfo/linaro-mm-sig</a> </blockquote></div>
