The most prominent change is the added documentation in the nal_h264.h header. The structs for the SPS and PPS NAL units and the function prototypes to convert between RBSP and the C structs are now accompanied by kernel-doc. Furthermore, I went through all TODOs and FIXMEs in the driver. This resulted in a cleaner handling of messages that are exchanged with the encoder firmware, better documentation of the limits that are imposed by the encoder firmware on the driver, fixed handling of failures during channel creation, and support for 4k video. v4l2-compliance also seems to be happy with the new version: v4l2-compliance SHA: 410942e345b889d09456f5f862ee6cd415d8ae59, 64 bits Compliance test for allegro device /dev/video4: Driver Info: Driver name : allegro Card type : Allegro DVT Video Encoder Bus info : platform:a0009000.video-codec Driver version : 5.0.0 Capabilities : 0x84208000 Video Memory-to-Memory Streaming Extended Pix Format Device Capabilities Device Caps : 0x04208000 Video Memory-to-Memory Streaming Extended Pix Format Detected Stateful Encoder Required ioctls: test VIDIOC_QUERYCAP: OK Allow for multiple opens: test second /dev/video4 open: OK test VIDIOC_QUERYCAP: OK test VIDIOC_G/S_PRIORITY: OK test for unlimited opens: OK Debug ioctls: test VIDIOC_DBG_G/S_REGISTER: OK test VIDIOC_LOG_STATUS: OK (Not Supported) Input ioctls: test VIDIOC_G/S_TUNER/ENUM_FREQ_BANDS: OK (Not Supported) test VIDIOC_G/S_FREQUENCY: OK (Not Supported) test VIDIOC_S_HW_FREQ_SEEK: OK (Not Supported) test VIDIOC_ENUMAUDIO: OK (Not Supported) test VIDIOC_G/S/ENUMINPUT: OK (Not Supported) test VIDIOC_G/S_AUDIO: OK (Not Supported) Inputs: 0 Audio Inputs: 0 Tuners: 0 Output ioctls: test VIDIOC_G/S_MODULATOR: OK (Not Supported) test VIDIOC_G/S_FREQUENCY: OK (Not Supported) test VIDIOC_ENUMAUDOUT: OK (Not Supported) test VIDIOC_G/S/ENUMOUTPUT: OK (Not Supported) test VIDIOC_G/S_AUDOUT: OK (Not Supported) Outputs: 0 Audio Outputs: 0 Modulators: 0 Input/Output configuration ioctls: test VIDIOC_ENUM/G/S/QUERY_STD: OK (Not Supported) test VIDIOC_ENUM/G/S/QUERY_DV_TIMINGS: OK (Not Supported) test VIDIOC_DV_TIMINGS_CAP: OK (Not Supported) test VIDIOC_G/S_EDID: OK (Not Supported) Control ioctls: test VIDIOC_QUERY_EXT_CTRL/QUERYMENU: OK test VIDIOC_QUERYCTRL: OK test VIDIOC_G/S_CTRL: OK test VIDIOC_G/S/TRY_EXT_CTRLS: OK test VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT: OK test VIDIOC_G/S_JPEGCOMP: OK (Not Supported) Standard Controls: 8 Private Controls: 0 Format ioctls: test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: OK test VIDIOC_G/S_PARM: OK (Not Supported) test VIDIOC_G_FBUF: OK (Not Supported) test VIDIOC_G_FMT: OK test VIDIOC_TRY_FMT: OK test VIDIOC_S_FMT: OK test VIDIOC_G_SLICED_VBI_CAP: OK (Not Supported) test Cropping: OK (Not Supported) test Composing: OK (Not Supported) test Scaling: OK Codec ioctls: test VIDIOC_(TRY_)ENCODER_CMD: OK test VIDIOC_G_ENC_INDEX: OK (Not Supported) test VIDIOC_(TRY_)DECODER_CMD: OK (Not Supported) Buffer ioctls: test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF: OK test VIDIOC_EXPBUF: OK test Requests: OK (Not Supported) Test input 0: Streaming ioctls: test read/write: OK (Not Supported) test blocking wait: OK Video Capture: Captured 10 buffers test MMAP (no poll): OK Video Capture: Captured 10 buffers test MMAP (select): OK Video Capture: Captured 10 buffers test MMAP (epoll): OK test USERPTR (no poll): OK (Not Supported) test USERPTR (select): OK (Not Supported) test DMABUF: Cannot test, specify --expbuf-device Total for allegro device /dev/video4: 51, Succeeded: 51, Failed: 0, Warnings: 0 Apart from that, there are a few cleanups to resolve checkpatch or compiler warnings.
