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/pci/cx23885/cx23885-video.c | 27 +++++++++++++++------------ 1 file changed, 15 insertions(+), 12 deletions(-) (limited to 'drivers/media/pci/cx23885/cx23885-video.c') diff --git a/drivers/media/pci/cx23885/cx23885-video.c b/drivers/media/pci/cx23885/cx23885-video.c index ec76470d12a4..b6a193df618a 100644 --- a/drivers/media/pci/cx23885/cx23885-video.c +++ b/drivers/media/pci/cx23885/cx23885-video.c @@ -104,12 +104,12 @@ void cx23885_video_wakeup(struct cx23885_dev *dev, buf = list_entry(q->active.next, struct cx23885_buffer, queue); - buf->vb.v4l2_buf.sequence = q->count++; - v4l2_get_timestamp(&buf->vb.v4l2_buf.timestamp); - dprintk(2, "[%p/%d] wakeup reg=%d buf=%d\n", buf, buf->vb.v4l2_buf.index, - count, q->count); + buf->vb.sequence = q->count++; + v4l2_get_timestamp(&buf->vb.timestamp); + dprintk(2, "[%p/%d] wakeup reg=%d buf=%d\n", buf, + buf->vb.vb2_buf.index, count, q->count); list_del(&buf->queue); - vb2_buffer_done(&buf->vb, VB2_BUF_STATE_DONE); + vb2_buffer_done(&buf->vb.vb2_buf, VB2_BUF_STATE_DONE); } int cx23885_set_tvnorm(struct cx23885_dev *dev, v4l2_std_id norm) @@ -329,9 +329,10 @@ static int queue_setup(struct vb2_queue *q, const struct v4l2_format *fmt, static int buffer_prepare(struct vb2_buffer *vb) { + struct vb2_v4l2_buffer *vbuf = to_vb2_v4l2_buffer(vb); struct cx23885_dev *dev = vb->vb2_queue->drv_priv; struct cx23885_buffer *buf = - container_of(vb, struct cx23885_buffer, vb); + container_of(vbuf, struct cx23885_buffer, vb); u32 line0_offset, line1_offset; struct sg_table *sgt = vb2_dma_sg_plane_desc(vb, 0); int field_tff; @@ -401,7 +402,7 @@ static int buffer_prepare(struct vb2_buffer *vb) BUG(); } dprintk(2, "[%p/%d] buffer_init - %dx%d %dbpp \"%s\" - dma=0x%08lx\n", - buf, buf->vb.v4l2_buf.index, + buf, buf->vb.vb2_buf.index, dev->width, dev->height, dev->fmt->depth, dev->fmt->name, (unsigned long)buf->risc.dma); return 0; @@ -409,7 +410,8 @@ static int buffer_prepare(struct vb2_buffer *vb) static void buffer_finish(struct vb2_buffer *vb) { - struct cx23885_buffer *buf = container_of(vb, + struct vb2_v4l2_buffer *vbuf = to_vb2_v4l2_buffer(vb); + struct cx23885_buffer *buf = container_of(vbuf, struct cx23885_buffer, vb); cx23885_free_buffer(vb->vb2_queue->drv_priv, buf); @@ -438,8 +440,9 @@ static void buffer_finish(struct vb2_buffer *vb) */ static void buffer_queue(struct vb2_buffer *vb) { + struct vb2_v4l2_buffer *vbuf = to_vb2_v4l2_buffer(vb); struct cx23885_dev *dev = vb->vb2_queue->drv_priv; - struct cx23885_buffer *buf = container_of(vb, + struct cx23885_buffer *buf = container_of(vbuf, struct cx23885_buffer, vb); struct cx23885_buffer *prev; struct cx23885_dmaqueue *q = &dev->vidq; @@ -455,7 +458,7 @@ static void buffer_queue(struct vb2_buffer *vb) if (list_empty(&q->active)) { list_add_tail(&buf->queue, &q->active); dprintk(2, "[%p/%d] buffer_queue - first active\n", - buf, buf->vb.v4l2_buf.index); + buf, buf->vb.vb2_buf.index); } else { buf->risc.cpu[0] |= cpu_to_le32(RISC_IRQ1); prev = list_entry(q->active.prev, struct cx23885_buffer, @@ -463,7 +466,7 @@ static void buffer_queue(struct vb2_buffer *vb) list_add_tail(&buf->queue, &q->active); prev->risc.jmp[1] = cpu_to_le32(buf->risc.dma); dprintk(2, "[%p/%d] buffer_queue - append to active\n", - buf, buf->vb.v4l2_buf.index); + buf, buf->vb.vb2_buf.index); } spin_unlock_irqrestore(&dev->slock, flags); } @@ -492,7 +495,7 @@ static void cx23885_stop_streaming(struct vb2_queue *q) struct cx23885_buffer, queue); list_del(&buf->queue); - vb2_buffer_done(&buf->vb, VB2_BUF_STATE_ERROR); + vb2_buffer_done(&buf->vb.vb2_buf, VB2_BUF_STATE_ERROR); } spin_unlock_irqrestore(&dev->slock, flags); } -- cgit v1.2.3
