I would just re-word this a bit, something like: VB2_USERPTR support doesn't make sense for drivers based on vb2_dma_contig, so just drop it. Otherwise, queues using vb2_dma_contig_memops causes v4l2-compliance to fail for VB2_USERPTR mode, due to buffer misalignment. > > Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@xxxxxxxxxxxxx> Acked-by: Helen Koike <helen.koike@xxxxxxxxxxxxx> > --- > drivers/staging/media/rkisp1/rkisp1-capture.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/staging/media/rkisp1/rkisp1-capture.c b/drivers/staging/media/rkisp1/rkisp1-capture.c > index 5f97af5cd95f..a006cd03228d 100644 > --- a/drivers/staging/media/rkisp1/rkisp1-capture.c > +++ b/drivers/staging/media/rkisp1/rkisp1-capture.c > @@ -1349,7 +1349,7 @@ static int rkisp1_register_capture(struct rkisp1_capture *cap) > > q = &node->buf_queue; > q->type = V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE; > - q->io_modes = VB2_MMAP | VB2_DMABUF | VB2_USERPTR; > + q->io_modes = VB2_MMAP | VB2_DMABUF; > q->drv_priv = cap; > q->ops = &rkisp1_vb2_ops; > q->mem_ops = &vb2_dma_contig_memops; > _______________________________________________ Linux-rockchip mailing list Linux-rockchip@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/linux-rockchip
