Added his Acked-by to most patches and closed review comments. Running v4l2-compliance, I noticed a new failure introduced by the way I now calculate the plane sizes in set/try_fmt. This is the function used to update per-plane bytesperline and sizeimage: static void ceu_update_plane_sizes(struct v4l2_plane_pix_format *plane, unsigned int bpl, unsigned int szimage) { if (plane->bytesperline < bpl) plane->bytesperline = bpl; if (plane->sizeimage < szimage) plane->sizeimage = szimage; } I'm seeing a failure as v4l2-compliance requires buffers with both bytesperline and sizeimage set to MAX_INT . Hans, is this expected from v4l2-compliance? How should I handle this, if that has to be handled by the single drivers? Apart from that, here it is the output of v4l2-compliance, with the last tests failing due to the above stated reason, and two errors in try/set format due to the fact the driver is not setting ycbcr encoding after it receives an invalid format. I would set those, but I'm not sure what it the correct value and not all mainline drivers do that. ------------------------------------------------------------------------------- v4l2-compliance SHA : 1d3c611dee82090d9456730e24af368b51dcb4a9 Driver Info: Driver name : renesas-ceu Card type : Renesas CEU e8210000.ceu Bus info : platform:renesas-ceu-e8210000.c Driver version: 4.14.0 Capabilities : 0x84201000 Video Capture Multiplanar Streaming Extended Pix Format Device Capabilities Device Caps : 0x04201000 Video Capture Multiplanar Streaming Extended Pix Format Compliance test for device /dev/video0 (not using libv4l2): Required ioctls: test VIDIOC_QUERYCAP: OK Allow for multiple opens: test second video 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 test VIDIOC_G/S_AUDIO: OK (Not Supported) Inputs: 1 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) Test input 0: 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 fail: v4l2-test-controls.cpp(782): subscribe event for control 'User Controls' failed test VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT: FAIL test VIDIOC_G/S_JPEGCOMP: OK (Not Supported) Standard Controls: 12 Private Controls: 0 Format ioctls: test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: OK fail: v4l2-test-formats.cpp(1162): ret && node->has_frmintervals test VIDIOC_G/S_PARM: FAIL test VIDIOC_G_FBUF: OK (Not Supported) test VIDIOC_G_FMT: OK fail: v4l2-test-formats.cpp(335): ycbcr_enc >= 0xff fail: v4l2-test-formats.cpp(451): testColorspace(pix_mp.pixelformat, pix_mp.colorspace, pix_mp.ycbcr_enc, pix_mp.quantization) fail: v4l2-test-formats.cpp(736): Video Capture Multiplanar is valid, but TRY_FMT failed to return a format test VIDIOC_TRY_FMT: FAIL fail: v4l2-test-formats.cpp(335): ycbcr_enc >= 0xff fail: v4l2-test-formats.cpp(451): testColorspace(pix_mp.pixelformat, pix_mp.colorspace, pix_mp.ycbcr_enc, pix_mp.quantization) fail: v4l2-test-formats.cpp(996): Video Capture Multiplanar is valid, but no S_FMT was implemented test VIDIOC_S_FMT: FAIL test VIDIOC_G_SLICED_VBI_CAP: OK (Not Supported) test Cropping: OK (Not Supported) test Composing: OK (Not Supported) test Scaling: OK (Not Supported) Codec ioctls: test VIDIOC_(TRY_)ENCODER_CMD: OK (Not Supported) 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 input 0: Total: 43, Succeeded: 39, Failed: 4, Warnings: 0 ------------------------------------------------------------------------------- Thanks j v5->v6: -
