2020-09-26media: vivid: Add support to the CSC APIDafna Hirschfeld
The CSC API (Colorspace conversion) allows userspace to try to configure the colorspace, transfer function, Y'CbCr/HSV encoding and the quantization for capture devices. This patch adds support to the CSC API in vivid. Using the CSC API, userspace is allowed to do the following: - Set the colorspace. - Set the xfer_func. - Set the ycbcr_enc function for YUV formats. - Set the hsv_enc function for HSV formats - Set the quantization for YUV and RGB formats.

2020-09-14media: media/v4l2: remove V4L2_FLAG_MEMORY_NON_CONSISTENT flagSergey Senozhatsky
The patch partially reverts some of the UAPI bits of the buffer cache management hints. Namely, the queue consistency (memory coherency) user-space hint because, as it turned out, the kernel implementation of this feature was misusing DMA_ATTR_NON_CONSISTENT. The patch reverts both kernel and user space parts: removes the DMA consistency attr functions, rolls back changes to v4l2_requestbuffers, v4l2_create_buffers structures and corresponding UAPI functions (plus compat32 layer) and cleans up the documentation.

2020-09-10media: v4l2-async: Document asd allocation requirementsLaurent Pinchart
The v4l2_async_notifier_add_subdev() function requires the asd pointer it receives to be allocated dynamically, but doesn't explicitly say so. Only one driver out of 13 get its right (atmel-sama5d2-isc.c, but with memory leaks in the error paths), clearly showing we have an issue. Update the v4l2_async_notifier_add_subdev() documentation to clearly state the allocation requirement. Whether this will be enough to avoid new offending code isn't certain, but it's a good first step nonetheless.

2020-09-03media: rc: harmonize infrared durations to microsecondsSean Young
rc-core kapi uses nanoseconds for infrared durations for receiving, and microseconds for sending. The uapi already uses microseconds for both, so this patch does not change the uapi. Infrared durations do not need nanosecond resolution. IR protocols do not have durations shorter than about 100 microseconds. Some IR hardware offers 250 microseconds resolution, which is sufficient for most protocols. Better hardware has 50 microsecond resolution and is enough for every protocol I am aware off. Unify on microseconds everywhere. This simplifies the code since less conversion between microseconds and nanoseconds needs to be done.

Applications are expected to fill V4L2_CID_MPEG_VIDEO_H264_SCALING_MATRIX if a non-flat scaling matrix applies to the picture. This is the case if SPS scaling_matrix_present_flag or PPS pic_scaling_matrix_present_flag are set, and should be handled by applications. On one hand, the PPS bitstream syntax element signals the presence of a Picture scaling matrix modifying the Sequence (SPS) scaling matrix. On the other hand, our flag should indicate if the scaling matrix V4L2 control is applicable to this request. Rename the flag from PPS_FLAG_PIC_SCALING_MATRIX_PRESENT to PPS_FLAG_SCALING_MATRIX_PRESENT, to avoid mixing this flag with bitstream syntax element pic_scaling_matrix_present_flag, and clarify the meaning of our flag.

2020-09-01media: uapi: h264: Clean slice invariants syntax elementsEzequiel Garcia
The H.264 specification requires in section 7.4.3 "Slice header semantics", that the following values shall be the same in all slice headers: pic_parameter_set_id frame_num field_pic_flag bottom_field_flag idr_pic_id pic_order_cnt_lsb delta_pic_order_cnt_bottom delta_pic_order_cnt[ 0 ] delta_pic_order_cnt[ 1 ] sp_for_switch_flag slice_group_change_cycle These bitstream fields are part of the slice header, and therefore passed redundantly on each slice. The purpose of the redundancy is to make the codec fault-tolerant in network scenarios. This is of course not needed to be reflected in the V4L2 controls, given the bitstream has already been parsed by applications. Therefore, move the redundant fields to the per-frame decode parameters control (DECODE_PARAMS). Field 'pic_parameter_set_id' is simply removed in this case, because the PPS control must currently contain the active PPS. Syntax elements dec_ref_pic_marking() and those related to pic order count, remain invariant as well, and therefore, the fields dec_ref_pic_marking_bit_size and pic_order_cnt_bit_size are also common to all slices.

2020-09-01media: uapi: h264: Clarify SLICE_BASED modeEzequiel Garcia
Currently, the SLICE_BASED and FRAME_BASED modes documentation is misleading and not matching the intended use-cases. Drop non-required fields SLICE_PARAMS 'start_byte_offset' and DECODE_PARAMS 'num_slices' and clarify the decoding modes in the documentation. On SLICE_BASED mode, a single slice is expected per OUTPUT buffer, and therefore 'start_byte_offset' is not needed (since the offset to the slice is the start of the buffer). This mode requires the use of CAPTURE buffer holding, and so the number of slices shall not be required. On FRAME_BASED mode, the devices are expected to take care of slice parsing. Neither SLICE_PARAMS are required (and shouldn't be exposed by frame-based drivers), nor the number of slices.

To reduce the API surface drop the size from the SLICE_PARAMS control. A follow-up change will remove other members in SLICE_PARAMS so we don't need to add padding fields here.

As specified, MaxFrameNum is 2^(log2_max_frame_num_minus4 + 4) and log2_max_frame_num_minus4 is in the range of 0 to 12, which means pic_num should be a 32-bit field. The v4l2_h264_dpb_entry struct needs to be padded to avoid a hole, which might be also useful to allow future uAPI extensions.

Slice header syntax element 'first_mb_in_slice' can point to the last macroblock, currently the field can only reference 65536 macroblocks which is insufficient for 8K videos. Although unlikely, a 8192x4320 video (where macroblocks are 16x16), would contain 138240 macroblocks on a frame. As per the H264 specification, 'first_mb_in_slice' can be up to PicSizeInMbs - 1, so increase the size of the field to 32-bits. Note that v4l2_ctrl_h264_slice_params struct will be modified in a follow-up commit, and so we defer its 64-bit padding.

2020-09-01media: uapi: h264: Split prediction weight parametersEzequiel Garcia
The prediction weight parameters are only required under certain conditions, which depend on slice header parameters. As specified in section 7.3.3 Slice header syntax, the prediction weight table is present if: ((weighted_pred_flag && (slice_type == P || slice_type == SP)) || \ (weighted_bipred_idc == 1 && slice_type == B)) Given its size, it makes sense to move this table to its control, so applications can avoid passing it if the slice doesn't specify it. Before this change struct v4l2_ctrl_h264_slice_params was 960 bytes. With this change, it's 188 bytes and struct v4l2_ctrl_h264_pred_weight is 772 bytes.

2020-08-28media: videobuf2-v4l2.c: add vb2_video_unregister_device helper functionHans Verkuil
If a driver calls (_)vb2_fop_release(), then such a driver should also call vb2_video_unregister_device() instead of video_unregister_device(). This helper will call vb2_queue_release() if a filehandle is marked as owner of the queue. This ensures that at unregister time any streaming is cancelled and all buffers are returned to userspace. This is very useful for complex drivers since this stops all streaming in all subdevs in the pipeline controlled by this video device. Otherwise this would be delayed until the owner filehandle is closed, which can be quite some time later.

Currently there is no method to know the correct order of the colors for a test image generated by tpg. Write a function that returns a string of colors' order given a tpg. It returns a NULL pointer in case of test patterns which do not have a well defined colors' order. Hence add a NULL check for text in tpg_gen_text().

2020-07-19media: tpg: change char argument to const charKaaira Gupta
Change the argument of type char * to const char * for function tpg_gen_text(). This function should take in a const char * as opposed to char * as it does not make changes to the text. This issue was found while passing the order of colors of tpg generated test image (which is a const char *) to this function.

2020-07-04media: vb2: Print the queue pointer in debug messagesLaurent Pinchart
When debugging issues that involve more than one video queue, messages related to multiple queues get interleaved without any easy way to tell which queue they relate to. Fix this by adding a queue name to vb2_queue, and printing it in all debug messages in the vb2 core and V4L2 layers. If the name isn't set by drivers, it is automatically filled with the queue direction and address.

The cec_adapter struct contained a waitq field that isn't used anywhere, so drop this. It also contained a phys_addrs array to store any reported physical addresses. However, this was never actually used, so this field is removed as well. The original idea was to let the core keep track of this information, but nothing was ever done with this.
