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/usb/stk1160/stk1160-v4l.c | 15 ++++++++------- drivers/media/usb/stk1160/stk1160-video.c | 12 ++++++------ drivers/media/usb/stk1160/stk1160.h | 2 +- 3 files changed, 15 insertions(+), 14 deletions(-) (limited to 'drivers/media/usb/stk1160') diff --git a/drivers/media/usb/stk1160/stk1160-v4l.c b/drivers/media/usb/stk1160/stk1160-v4l.c index e12b10352871..10e35e6479ad 100644 --- a/drivers/media/usb/stk1160/stk1160-v4l.c +++ b/drivers/media/usb/stk1160/stk1160-v4l.c @@ -695,8 +695,9 @@ static void buffer_queue(struct vb2_buffer *vb) { unsigned long flags; struct stk1160 *dev = vb2_get_drv_priv(vb->vb2_queue); + struct vb2_v4l2_buffer *vbuf = to_vb2_v4l2_buffer(vb); struct stk1160_buffer *buf = - container_of(vb, struct stk1160_buffer, vb); + container_of(vbuf, struct stk1160_buffer, vb); spin_lock_irqsave(&dev->buf_lock, flags); if (!dev->udev) { @@ -704,7 +705,7 @@ static void buffer_queue(struct vb2_buffer *vb) * If the device is disconnected return the buffer to userspace * directly.
