With the Aspeed chip acting as a service processor, the Video Engine can capture the host processor graphics output. This series adds a V4L2 driver for the VE, providing the usual V4L2 streaming interface by way of videobuf2. Each frame, the driver triggers the hardware to capture the host graphics output and compress it to JPEG format. v4l2-compliance SHA: ac9596560fedb3cd29148ef90b03778d76f1cd9a, 32 bits Compliance test for device /dev/video0: Driver Info: Driver name : aspeed-video Card type : Aspeed Video Engine Bus info : platform:aspeed-video Driver version : 4.18.19 Capabilities : 0x85200001 Video Capture Read/Write Streaming Extended Pix Format Device Capabilities Device Caps : 0x05200001 Video Capture Read/Write Streaming Extended Pix Format Required ioctls: test VIDIOC_QUERYCAP: OK Allow for multiple opens: test second /dev/video0 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 (Not Supported) 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 test VIDIOC_DV_TIMINGS_CAP: OK test VIDIOC_G/S_EDID: OK (Not Supported) Control ioctls (Input 0): 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(831): failed to find event for control 'Chroma Subsampling' test VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT: FAIL test VIDIOC_G/S_JPEGCOMP: OK (Not Supported) Standard Controls: 3 Private Controls: 0 Format ioctls (Input 0): test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: OK test VIDIOC_G/S_PARM: OK 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 (Not Supported) Codec ioctls (Input 0): 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 (Input 0): 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 test blocking wait: OK test MMAP: OK test USERPTR: OK (Not Supported) test DMABUF: Cannot test, specify --expbuf-device Total: 48, Succeeded: 47, Failed: 1, Warnings: 0 Changes since v5: - Rework resolution change and v4l2 timings functions again with active and detected timings. - Renamed a few things. - Fixed polarities in the timings. Changes since v4: - Set real min and max resolution in enum_dv_timings - Add check for vb2_is_busy before settings the timings - Set max frame rate to the actual max rather than max + 1 - Correct the input status to 0. - Rework resolution change to only set the relevant h/w regs during startup or when set_timings is called. Changes since v3: - Switch update reg function to use u32 clear rather than unsigned long mask - Add timing information from host VGA signal - Fix binding documentation mispelling - Fix upper case hex values - Add wait_prepare and wait_finish - Set buffer state to queued (rather than error) if streaming fails to start - Switch engine busy print statement to error - Removed a couple unecessary type assignments in v4l2 ioctls - Added query_dv_timings, fixed get_dv_timings - Corrected source change event to fire if and only if size actually changes - Locked open and release Changes since v2: - Switch to streaming interface. This involved a lot of changes. - Rework memory allocation due to using videobuf2 buffers, but also only allocate the necessary size of source buffer rather than the max size Changes since v1: - Removed le32_to_cpu calls for JPEG header data - Reworked v4l2 ioctls to be compliant. - Added JPEG controls - Updated devicetree docs according to Rob's suggestions. - Added myself to MAINTAINERS Eddie James (2): dt-bindings: media: Add Aspeed Video Engine binding documentation media: platform: Add Aspeed Video Engine driver .../devicetree/bindings/media/aspeed-video.txt | 26 + MAINTAINERS | 8 + drivers/media/platform/Kconfig | 9 + drivers/media/platform/Makefile | 1 + drivers/media/platform/aspeed-video.c | 1719 ++++++++++++++++++++ 5 files changed, 1763 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/aspeed-video.txt create mode 100644 drivers/media/platform/aspeed-video.c
