When dealing with interlaced frames, reference lists must tell if each particular reference is meant for top or bottom field. This info is currently not provided at all in the H264 related controls. Change reference lists to hold a structure, which specifies an index into the DPB array and the field/frame specification for the picture. Currently the only user of these lists is Cedrus which is just compile fixed here. Actual usage of will come in a following commit. Signed-off-by:

The unit of exposure value is different from other OmniVision sensors, driver will divide by 2 before set register, the exposure range exposed by v4l2 ctrl to user should be same as others, so the calculation for the maximum exposure value in current driver need be fixed. Signed-off-by:

1) the numerator and/or denominator might be 0, in that case fall back to the default frame interval. This is per the spec and this caused a v4l2-compliance failure. 2) the updated frame interval wasn't returned in the s_frame_interval subdev op. Signed-off-by:

Currently the error return from the call to max9286_read is masked with 0xf0 so the following check for a negative error return is never true. Fix this by checking for an error first, then masking the return value for subsequent conflink_mask checking.

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

The OTP data was not ready after registered as nvmem device, it is risky as the nvmem read may happen once the device exists, this patch get the OTP data ready before registering the nvmem device. OTP data missing should not break the normal camera sensor probe, so use a warning instead of an error message. Signed-off-by:

The parallel port nodes should be numbered 1 and 2, not 0 and 1 for A and B respectively. The driver has always implemented 1 and 2 and the in-tree Goni DTS uses 1 as port A as well. Update the documentation to match this behaviour. Signed-off-by:

vidioc_streamoff can be called multiple times from userspace, but we should only call media_pipeline_stop when we're actually setup. This became more noticeable after commit 2a2599c6 ("[media] media: entity: Catch unbalanced media_pipeline_stop calls") was merged as it added a WARN for unbalanced calls to media_pipeline_stop.

On some devices, there may be multiple camera sensors attached to the same port. Make sure we probe all of them, not just the first one. Signed-off-by:

Jonathan Bakker authored
Instead of keeping a local copy of how many sensors we've probed (which may not even properly represent the number of sensors probed if we have a port without a sensor), use the global num_sensors counter that has the actual number used. This will also make it easier to add support for multiple sensors being connected to the same port. Signed-off-by:

Not all devices use the CSIS device, some may use the FIMC directly in which case the CSIS device isn't registered. This leads to a nullptr exception when starting the stream as the CSIS device is always referenced. Instead, if getting the CSIS device fails, try getting the FIMC directly to check if we are using the subdev API Signed-off-by:

When the post-processor is enabled, the driver allocates "shadow buffers" which are used for the decoder core, and exposes the post-processed buffers to userspace. For this reason, extra motion vector space has to be allocated on the shadow buffers, which the driver wasn't doing. Fix it. This fix should address artifacts on high profile bitstreams.

Ezequiel Garcia authored
If the bitstream and the application are incorrectly configuring the reference pictures, the hardware will need to fallback to using some other reference picture. When the post-processor is enabled, the fallback buffer should be a shadow buffer (postproc.dec_q), and not a CAPTURE queue buffer, since the latter is post-processed and not really the output of the decoder core.

list_for_each_entry is able to handle an empty list. The only effect of avoiding the loop is not initializing the index variable. Drop list_empty tests in cases where these variables are not used. Note that list_for_each_entry is defined in terms of list_first_entry, which indicates that it should not be used on an empty list. But in list_for_each_entry, the element obtained by list_first_entry is not really accessed, only the address of its list_head field is compared to the address of the list head, so the list_first_entry is safe. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) <smpl> @@ expression x,e; iterator name list_for_each_entry; statement S; identifier i; @@ -if (!(list_empty(x))) { list_for_each_entry(i,x,...)
