2020-12-03media: vicodec: mark the stateless FWHT API as stableHans Verkuil
The FWHT stateless 'uAPI' was staging and marked explicitly in the V4L2 specification that it will change and is unstable. Note that these control IDs were never exported as a public API, they were only defined in kernel-local headers (fwht-ctrls.h). Now, the FWHT stateless controls is ready to be part of the stable uAPI. While not too late: - Rename V4L2_CID_MPEG_VIDEO_FWHT_PARAMS to V4L2_CID_STATELESS_FWHT_PARAMS. - Move the contents of fwht-ctrls.h to v4l2-controls.h. - Move the public parts of drivers/media/test-drivers/vicodec/codec-fwht.h to v4l2-controls.h. - Add V4L2_CTRL_TYPE_FWHT_PARAMS control initialization and validation. - Add p_fwht_params to struct v4l2_ext_control.

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.

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.

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.

2019-11-10media: v4l2-ctrl: Lock main_hdl on operations of requests_queued.Pi-Hsun Shih
There's a race condition between the list_del_init in the v4l2_ctrl_request_complete, and the list_add_tail in the v4l2_ctrl_request_queue, since they can be called in different thread and the requests_queued list is not protected by a lock. This can lead to that the v4l2_ctrl_handler is still in the requests_queued list while the request_is_queued is already set to false, which would cause use-after-free if the v4l2_ctrl_handler is later released. Fix this by locking the ->lock of main_hdl (which is the owner of the requests_queued list) when doing list operations on the ->requests_queued list.

2019-10-24media: v4l: Add definitions for HEVC stateless decodingPaul Kocialkowski
This introduces the required definitions for HEVC decoding support with stateless VPUs. The controls associated to the HEVC slice format provide the required meta-data for decoding slices extracted from the bitstream. They are not exported to the public V4L2 API since reworking this API will likely be needed for covering various use-cases and new hardware. Multi-slice decoding is exposed as a valid decoding mode to match current H.264 support but it is not yet implemented. The interface comes with the following limitations: * No custom quantization matrices (scaling lists); * Support for a single temporal layer only; * No slice entry point offsets support; * No conformance window support; * No VUI parameters support; * No support for SPS extensions: range, multilayer, 3d, scc, 4 bits; * No support for PPS extensions: range, multilayer, 3d, scc, 4 bits.
