It also supports H and V flip, which among others requires to write the start address (i.e. the 1st offset to write, at the end of the buffer or line) in more registers for Y and, for planar formats, U and V. Add minimal hooks in VI to allow per-SoC optional support to those features: - variables in struct tegra_vi for the U and V buffer base offsets - variables in struct tegra_vi for the Y, U and V buffer start offsets - an optional per-soc VI operation to compute those values on queue setup Signed-off-by: Luca Ceresoli --- No changes in v2 --- drivers/staging/media/tegra-video/vi.c | 4 ++++ drivers/staging/media/tegra-video/vi.h | 14 ++++++++++++++ 2 files changed, 18 insertions(+) diff --git a/drivers/staging/media/tegra-video/vi.c b/drivers/staging/media/tegra-video/vi.c index 854ffb4b5617..ebb502a45e96 100644 --- a/drivers/staging/media/tegra-video/vi.c +++ b/drivers/staging/media/tegra-video/vi.c @@ -92,6 +92,7 @@ tegra_get_format_by_fourcc(struct tegra_vi *vi, u32 fourcc) /* * videobuf2 queue operations */ + static int tegra_channel_queue_setup(struct vb2_queue *vq, unsigned int *nbuffers, unsigned int *nplanes, @@ -107,6 +108,9 @@ static int tegra_channel_queue_setup(struct vb2_queue *vq, sizes[0] = chan->format.sizeimage; alloc_devs[0] = chan->vi->dev; + if (chan->vi->ops->channel_queue_setup) + chan->vi->ops->channel_queue_setup(chan); + return 0; } diff --git a/drivers/staging/media/tegra-video/vi.h b/drivers/staging/media/tegra-video/vi.h index ba563cd17296..a23ee8800d33 100644 --- a/drivers/staging/media/tegra-video/vi.h +++ b/drivers/staging/media/tegra-video/vi.h @@ -47,6 +47,7 @@ struct tegra_vi_channel; * @channel_host1x_syncpt_free: free all synchronization points * @vi_fmt_align: modify `pix` to fit the hardware alignment * requirements and fill image geometry + * @channel_queue_setup: additional operations at the end of vb2_ops::queue_setup * @vi_start_streaming: starts media pipeline, subdevice streaming, sets up * VI for capture and runs capture start and capture finish * kthreads for capturing frames to buffer and returns them back. @@ -58,6 +59,7 @@ struct tegra_vi_ops { int (*channel_host1x_syncpt_init)(struct tegra_vi_channel *chan); void (*channel_host1x_syncpt_free)(struct tegra_vi_channel *chan); void (*vi_fmt_align)(struct v4l2_pix_format *pix, unsigned int bpp); + void (*channel_queue_setup)(struct tegra_vi_channel *chan); int (*vi_start_streaming)(struct vb2_queue *vq, u32 count); void (*vi_stop_streaming)(struct vb2_queue *vq); }; @@ -148,6 +150,12 @@ struct tegra_vi { * @queue: vb2 buffers queue * @sequence: V4L2 buffers sequence number * + * @addr_offset_u: U plane base address, relative to buffer base address (only for planar) + * @addr_offset_v: V plane base address, relative to buffer base address (only for planar) + * @start_offset: 1st Y byte to write, relative to buffer base address (for H/V flip) + * @start_offset_u: 1st U byte to write, relative to buffer base address (for H/V flip) + * @start_offset_v: 1st V byte to write, relative to buffer base address (for H/V flip) + * * @capture: list of queued buffers for capture * @start_lock: protects the capture queued list * @done: list of capture done queued buffers @@ -188,6 +196,12 @@ struct tegra_vi_channel { struct vb2_queue queue; u32 sequence; + unsigned int addr_offset_u; + unsigned int addr_offset_v; + unsigned int start_offset; + unsigned int start_offset_u; + unsigned int start_offset_v; + struct list_head capture; /* protects the capture queued list */ spinlock_t start_lock;
