This is v6 of the Allegro DVT H.264 encoder driver found in the EV family of the Xilinx ZynqMP platform. Only minor changes this time. I dropped the implementation of the selection api, removed all references mentioning the decoder, and fixed a few issues reported by sparse and smatch. The v4l2-compliance result using the current vicodec branch is v4l2-compliance SHA: c2ad13e4b7aef9ae160303189c67a91e1775f025, 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 : 5.1.0 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: 10 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 60 buffers test MMAP (select): OK Video Capture: Captured 60 buffers test MMAP (epoll): OK test USERPTR (select): OK (Not Supported) test DMABUF: Cannot test, specify --expbuf-device Total for allegro device /dev/video4: 49, Succeeded: 49, Failed: 0, Warnings: 0 I observed that the "MMAP (select)" test occasionally fails, because the test did not receive an V4L2_EVENT_EOS when dequeuing a buffer with V4L2_BUF_FLAG_LAST being set. The driver always queues the event before returning the last buffer and the "MMAP (epoll)" does not fail. Thus, I decided to send the series anyway.
