From 2d7007153f0c9b1dd00c01894df7d26ddc32b79f Mon Sep 17 00:00:00 2001 From: Junghak Sung Date: Tue, 22 Sep 2015 10:30:30 -0300 Subject: [media] media: videobuf2: Restructure vb2_buffer Remove v4l2 stuff - v4l2_buf, v4l2_plane - from struct vb2_buffer. Add new member variables - bytesused, length, offset, userptr, fd, data_offset - to struct vb2_plane in order to cover all information of v4l2_plane. struct vb2_plane { unsigned int bytesused; unsigned int length; union { unsigned int offset; unsigned long userptr; int fd; } m; unsigned int data_offset; } Replace v4l2_buf with new member variables - index, type, memory - which are common fields for buffer management. struct vb2_buffer { unsigned int index; unsigned int type; unsigned int memory; unsigned int num_planes; struct vb2_plane planes[VIDEO_MAX_PLANES]; }; v4l2 specific fields - flags, field, timestamp, timecode, sequence - are moved to vb2_v4l2_buffer in videobuf2-v4l2.c struct vb2_v4l2_buffer { struct vb2_buffer vb2_buf; __u32 flags; __u32 field; struct timeval timestamp; struct v4l2_timecode timecode; __u32 sequence; }; Signed-off-by: Junghak Sung Signed-off-by: Geunyoung Kim Acked-by: Seung-Woo Kim Acked-by: Inki Dae Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/platform/coda/coda-common.c | 21 +++++++++++---------- 1 file changed, 11 insertions(+), 10 deletions(-) (limited to 'drivers/media/platform/coda/coda-common.c') diff --git a/drivers/media/platform/coda/coda-common.c b/drivers/media/platform/coda/coda-common.c index 998fe6614b33..60336eec75af 100644 --- a/drivers/media/platform/coda/coda-common.c +++ b/drivers/media/platform/coda/coda-common.c @@ -84,9 +84,9 @@ unsigned int coda_read(struct coda_dev *dev, u32 reg) } void coda_write_base(struct coda_ctx *ctx, struct coda_q_data *q_data, - struct vb2_buffer *buf, unsigned int reg_y) + struct vb2_v4l2_buffer *buf, unsigned int reg_y) { - u32 base_y = vb2_dma_contig_plane_dma_addr(buf, 0); + u32 base_y = vb2_dma_contig_plane_dma_addr(&buf->vb2_buf, 0); u32 base_cb, base_cr; switch (q_data->fourcc) { @@ -684,17 +684,17 @@ static int coda_qbuf(struct file *file, void *priv, } static bool coda_buf_is_end_of_stream(struct coda_ctx *ctx, - struct vb2_buffer *buf) + struct vb2_v4l2_buffer *buf) { struct vb2_queue *src_vq; src_vq = v4l2_m2m_get_vq(ctx->fh.m2m_ctx, V4L2_BUF_TYPE_VIDEO_OUTPUT); return ((ctx->bit_stream_param & CODA_BIT_STREAM_END_FLAG) && - (buf->v4l2_buf.sequence == (ctx->qsequence - 1))); + (buf->sequence == (ctx->qsequence - 1))); } -void coda_m2m_buf_done(struct coda_ctx *ctx, struct vb2_buffer *buf, +void coda_m2m_buf_done(struct coda_ctx *ctx, struct vb2_v4l2_buffer *buf, enum vb2_buffer_state state) { const struct v4l2_event eos_event = { @@ -702,7 +702,7 @@ void coda_m2m_buf_done(struct coda_ctx *ctx, struct vb2_buffer *buf, }; if (coda_buf_is_end_of_stream(ctx, buf)) { - buf->v4l2_buf.flags |= V4L2_BUF_FLAG_LAST; + buf->flags |= V4L2_BUF_FLAG_LAST; v4l2_event_queue_fh(&ctx->fh, &eos_event); } @@ -1175,6 +1175,7 @@ static int coda_buf_prepare(struct vb2_buffer *vb) static void coda_buf_queue(struct vb2_buffer *vb) { + struct vb2_v4l2_buffer *vbuf = to_vb2_v4l2_buffer(vb); struct coda_ctx *ctx = vb2_get_drv_priv(vb->vb2_queue); struct vb2_queue *vq = vb->vb2_queue; struct coda_q_data *q_data; @@ -1193,12 +1194,12 @@ static void coda_buf_queue(struct vb2_buffer *vb) if (vb2_get_plane_payload(vb, 0) == 0) coda_bit_stream_end_flag(ctx); mutex_lock(&ctx->bitstream_mutex); - v4l2_m2m_buf_queue(ctx->fh.m2m_ctx, vb); + v4l2_m2m_buf_queue(ctx->fh.m2m_ctx, vbuf); if (vb2_is_streaming(vb->vb2_queue)) coda_fill_bitstream(ctx, true); mutex_unlock(&ctx->bitstream_mutex); } else { - v4l2_m2m_buf_queue(ctx->fh.m2m_ctx, vb); + v4l2_m2m_buf_queue(ctx->fh.m2m_ctx, vbuf); } } @@ -1247,7 +1248,7 @@ static int coda_start_streaming(struct vb2_queue *q, unsigned int count) struct coda_ctx *ctx = vb2_get_drv_priv(q); struct v4l2_device *v4l2_dev = &ctx->dev->v4l2_dev; struct coda_q_data *q_data_src, *q_data_dst; - struct vb2_buffer *buf; + struct vb2_v4l2_buffer *buf; int ret = 0; q_data_src = get_q_data(ctx, V4L2_BUF_TYPE_VIDEO_OUTPUT); @@ -1338,7 +1339,7 @@ static void coda_stop_streaming(struct vb2_queue *q) { struct coda_ctx *ctx = vb2_get_drv_priv(q); struct coda_dev *dev = ctx->dev; - struct vb2_buffer *buf; + struct vb2_v4l2_buffer *buf; unsigned long flags; bool stop; -- cgit v1.2.3
