The core code for PREPARE_BUF didn't take the multiplanar case into account, which might cause page faults. Handle PREPARE_BUF just like QUERYBUF and QBUF/DQBUF. Signed-off-by:

length should be set to num_planes in __fill_v4l2_buffer(). That way the caller knows how many planes there are in the buffer. Signed-off-by:
-
Hans Verkuil authored
The plane verification should be done before actually queuing or dequeuing buffers, so move it out of __fill_v4l2_buffer and __fill_vb_buffer and call it as a separate step. This also makes it possible to change the return type of __fill_v4l2/vb_buffer to void. The dqbuf case took some special care: before removing a buffer from the done_list you have to verify that the receiving v4l2_buffer has enough room for all the planes. The number of planes can differ between buffers due to the fact that buffers for other formats can be prepared using VIDIOC_PREPARE_BUF. Signed-off-by:

vpif_display relied on a 1-1 mapping of output and subdev. This is not necessarily the case. Separate the two. So there is a list of subdevs and a list of outputs. Each output refers to a subdev and has routing information. An output does not have to have a subdev. The initial output for each channel is set to the fist output. Currently missing is support for associating multiple subdevs with an output. Signed-off-by:

The s_routing function should not try to detect a signal. It is a really bad idea to try to detect a valid video signal and return an error if you can't. Changing input should do just that and nothing more. Also don't power on the ADCs on s_routing, instead do that on querystd. Signed-off-by:

This makes it easier to have outputs without subdevs. This needs more work. The way the outputs are configured should be identical to how inputs are configured. Signed-off-by:

The V4L2_PIX_FMT_S5C_YUYV_JPG image formats consists of 2 planes, the first containing interleaved JPEG/YUYV data and the second containing meta data describing the interleaving method. The image data is transferred with MIPI-CSI "User Defined Byte-Based Data 1" type and is captured to memory by FIMC DMA engine. The meta data is transferred using MIPI-CSI2 "Embedded 8-bit non Image Data" and it is captured in the MIPI-CSI slave device and copied to the bridge provided buffer. To make sure the size of allocated buffers is correct for the subdevs configuration when VIDIOC_STREAMON ioctl is invoked, an additional check is added at the video pipeline validation function. Flag FMT_FLAGS_COMPRESSED indicates the buffer size must be retrieved from a sensor subdev. Signed-off-by:

MIPI-CSI has internal memory mapped buffers for the frame embedded (non-image) data. There are two buffers, for even and odd frames which need to be saved after an interrupt is raised. The packet data buffers size is 4 KiB and there is no status register in the hardware where the actual non-image data size can be read from. Hence the driver copies whole packet data buffer into a buffer provided by the FIMC driver. This will form a separate plane in the user buffer. When FIMC DMA engine is stopped by the driver due the to user space not keeping up with buffer de-queuing the MIPI-CSIS will still run, however it must discard data which is not captured by FIMC. Which frames are actually capture by MIPI-CSIS is determined by means of the s_tx_buffer subdev callback. When it is not called after a single embedded data frame has been captured and copied and before next embedded data frame interrupt occurrs, subsequent embedded data frames will be dropped.

This patch adds definition of the Samsung S5C73M3 camera specific image format. V4L2_PIX_FMT_S5C_UYVY_JPG is a two-planar format, the first plane contains interleaved UYVY and JPEG data followed by meta-data. The second plane contains additional meta-data needed for extracting JPEG and UYVY data stream from the first plane. Signed-off-by:

This patch adds media bus pixel code for the interleaved JPEG/UYVY image format used by S5C73MX Samsung cameras. This interleaved image data is transferred on MIPI-CSI2 bus as User Defined Byte-based Data. It also defines an experimental vendor and device specific media bus formats section and adds related DocBook documentation. Signed-off-by:

Add subdev callbacks for setting up parameters of the frame on media bus that are not exposed to user space directly. This is just an initial, mostly stub implementation. struct v4l2_mbus_frame_desc is intended to be extended with sub-structures specific to a particular hardware media bus. For now these new callbacks are used only to query or specify maximum size of a compressed or hybrid (container) media bus frame in octets. Signed-off-by:

The s_rx_buffer callback allows the host to set buffer for a data being received by the subdev, e.g. non-image frame (meta) data. This callback can be implemented by subdevice like a MIPI CSI2 receiver, allowing the host driver to gather additional data into frame buffer passed to user space. Signed-off-by:
