The IPU can only capture RGB565 with two 8-bit cycles in bayer/generic mode on the parallel bus, compared to a specific mode on MIPI CSI-2. To handle this, we extend imx_media_pixfmt with a cycles per pixel field, which is used for generic formats on the parallel bus. Based on the selected format and bus, we then update the width to account for the multiple cycles per pixel. Signed-off-by:

By checking and handling the internal IPU formats (ARGB or AYUV) first, we don't need to check whether it's a bayer format, as we can default to passing the input format on in all other cases. This simplifies handling the different configurations for RGB565 between parallel and MIPI CSI-2, as we don't need to check the details of the format anymore. Signed-off-by:

Handle parallel subdevices in link_notify callback. If the notified link involves a parallel subdevice, do not change routing of the VIN-CSI-2 devices and mark the VIN instance as using a parallel input. If the CSI-2 link setup succeeds instead, mark the VIN instance as using CSI-2. Signed-off-by:

When running with media-controller link the parallel input media entities with the VIN entities at 'complete' callback time. To create media links the v4l2_device should be registered first. Check if the device is already registered, to avoid double registrations. Signed-off-by:

The rcar-vin driver so far had a mutually exclusive code path for handling parallel and CSI-2 video input subdevices, with only the CSI-2 use case supporting media-controller. As we add support for parallel inputs to Gen3 media-controller compliant code path now parse both port@0 and port@1, handling the media-controller use case in the parallel bound/unbind notifier operations.

Media bus configuration flags and media bus type were so far a property of each VIN instance, as the subdevice they were connected to was immutable during the whole system life time. With the forth-coming introduction of parallel input devices support, a VIN instance can have the subdevice it is connected to switched at runtime, from a CSI-2 subdevice to a parallel one and viceversa, through the modification of links between media entities in the media controller graph. To avoid discarding the per-subdevice configuration flags retrieved by v4l2_fwnode parsing facilities, cache them in the 'rvin_graph_entity' member of each VIN instance, opportunely renamed to 'rvin_parallel_entity'. Also modify the register configuration function to take mbus flags into account when running on a bus type that supports them. The media bus type currently in use will be updated in a follow-up patch to the link state change notification function. Signed-off-by:

During the notifier initialization, memory for the list of associated async subdevices is reserved during the fwnode endpoint parsing from the v4l2-async framework. If the notifier registration fails, that memory should be released and the notifier 'cleaned up'. Catch the notifier registration error and perform the cleanup both for the group and the parallel notifiers. Signed-off-by:

As CSI-2 subdevices are shared between several VIN instances, a shared notifier to collect the CSI-2 async subdevices is required. So far, the rcar-vin driver used the notifier of the last VIN instance to probe but with the forth-coming introduction of parallel input subdevices support in mc-compliant code path, each VIN may register its own notifier if any parallel subdevice is connected there. To avoid registering a notifier twice (once for parallel subdev and one for the CSI-2 subdevs) create a group notifier, shared by all the VIN instances. Signed-off-by:

A memory-to-memory pipeline device consists in three entities: two DMA engine and one video processing entities. The DMA engine entities are linked to a V4L interface. This commit add a new v4l2_m2m_{un}register_media_controller API to register this topology. For instance, a typical mem2mem device topology would look like this: Device topology - entity 1: source (1 pad, 1 link) type Node subtype V4L flags 0 pad0: Source -> "proc":1 [ENABLED,IMMUTABLE] - entity 3: proc (2 pads, 2 links) type Node subtype Unknown flags 0 pad0: Source -> "sink":0 [ENABLED,IMMUTABLE] pad1: Sink <- "source":0 [ENABLED,IMMUTABLE] - entity 6: sink (1 pad, 1 link) type Node subtype V4L flags 0 pad0: Sink <- "proc":0 [ENABLED,IMMUTABLE] [hans.verkuil@cisco.com: mark interface links as IMMUTABLE] Suggested-by: -
Hans Verkuil authored
Currently links between entities and an interface are just marked as ENABLED. But (at least today) these links cannot be disabled by userspace or the driver, so they should also be marked as IMMUTABLE. It might become possible that drivers can disable such links (if for some reason the device node cannot be used), so we might need to add a new link flag at some point to mark interface links that can be changed by the driver but not by userspace.

When you switch from auto to manual mode for an auto-cluster (e.g. autogain+gain controls), then the current HW value has to be copied to the current control value. However, has_changed was never set to true, so new_to_cur didn't actually copy this value. Reported-by:

Padding the bitstream buffer is not enough to reliably avoid prefetch failures. Picture runs with the next buffer's header already visible to the CODA7541 succeed much more reliably, so always queue two JPEG frames into the bitstream buffer. Signed-off-by:

The hardware codec is not colorspace aware. We should trust userspace to set the correct colorimetry information on the OUTPUT queue and mirror the exact same setting on the CAPTURE queue. There is no reason to restrict colorspace to JPEG for JPEG images, if userspace injects the correct colorspace information into the JPEG headers after encoding.

In the vivid driver you want gain to continuous change while autogain is on. However, dev->jiffies_vid_cap doesn't actually change. It probably did in the past, but changes in the code caused this to be a fixed value that is only set when you start streaming. Replace it by jiffies, which is always changing.

When the imx-media driver was initially merged, there was a conflict with 8d67ae25 ("media: v4l2-ctrls: Reserve controls for MAX217X") which was not fixed up correctly, resulting in V4L2_CID_USER_MAX217X_BASE and V4L2_CID_USER_IMX_BASE taking on the same value. Fix by assigning imx CID base the next available range at 0x10b0. Signed-off-by:

The vb2_queue will soon be mandatory. The videobuf2 core will throw a verbose warning if it's not set. The stk1160 driver is setting the queue lock, but after the vb2_queue_init call. Avoid the warning by setting the lock before the queue initialization. Signed-off-by:

This driver is currently specifying a video_device lock, which means it is protecting all the ioctls (including queue ioctls) with a single mutex. It's therefore straightforward to implement wait_prepare and wait_finish, by explicitly setting the vb2_queue lock. Having these callbacks releases the queue lock while blocking, which improves latency by allowing for example streamoff or qbuf operations while waiting in dqbuf. Signed-off-by:

Currently, this driver does not serialize its video4linux ioctls, which is a bug, as race conditions might appear. In addition, video_device and vb2_queue locks are now both mandatory. Add them, and implement wait_prepare and wait_finish. To stay on the safe side, this commit uses a single mutex for both locks. Better latency can be obtained by separating these if needed.

For m2m devices the vdev->queue lock was always taken instead of the lock for the specific capture or output queue. Now that we pushed the locking down into __video_do_ioctl() we can pick the correct lock and potentially improve the performance of m2m devices. Signed-off-by:
