The driver implements V4L2, Media controller and V4L2 subdev interfaces. Camera sensor using V4L2 subdev interface in the kernel is supported. The driver is implemented using as a reference the Qualcomm Camera Subsystem driver for Android as found in Code Aurora [1]. The driver is tested on Dragonboard 410C (APQ8016) with one and two OV5645 camera sensors. media-ctl [2] and yavta [3] applications were used for testing. Also Gstreamer 1.10.4 with v4l2src plugin is supported. More information is present in the document added by the third patch. ------------------------------------------------------------------------------- Patchset Changelog: Version 2: - patches 01-10 are updated from v1 following the review received and bugs and limitaitons found after v1 was posted. The updates include: - return buffers on unsuccessful stream on; - fill device capabilities in struct video_device; - simplify v4l2 file handle usage - no custom struct for file handle; - use vb2_fop_poll and vb2_fop_mmap v4l2 file operations; - add support for read/write I/O; - add support for DMABUF streaming I/O; - add support for EXPBUF and PREPARE_BUF ioctl; - avoid a race condition between device unbind and userspace access to the video node; - use non-contiguous memory for video buffers; - switch to V4L2 multi-planar API; - add useful error messages in case of an overflow in ISPIF; - other small and style fixes. - patches 11-19 are new (they were not ready/posted with v1). I'm including these in this patchset as they add valuable features and may be desired for a real world usage of the driver. ------------------------------------------------------------------------------- The patchset depends on: v4l: Add packed Bayer raw12 pixel formats [4] ------------------------------------------------------------------------------- V4L2 compliance test result: $ v4l2-compliance -s -d /dev/video0 v4l2-compliance SHA : ce237eefc1f6dafafc0e1fe3a5fd9f075d3fd066 Driver Info: Driver name : qcom-camss Card type : Qualcomm Camera Subsystem Bus info : platform:1b0ac00.camss Driver version: 4.9.27 Capabilities : 0x85201000 Video Capture Multiplanar Read/Write Streaming Extended Pix Format Device Capabilities Device Caps : 0x05201000 Video Capture Multiplanar Read/Write 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 (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 (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 (Not Supported) test VIDIOC_QUERYCTRL: OK (Not Supported) test VIDIOC_G/S_CTRL: OK (Not Supported) test VIDIOC_G/S/TRY_EXT_CTRLS: OK (Not Supported) test VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT: OK (Not Supported) test VIDIOC_G/S_JPEGCOMP: OK (Not Supported) Standard Controls: 0 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 (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: Streaming ioctls: test read/write: OK test MMAP: OK test USERPTR: OK (Not Supported) test DMABUF: Cannot test, specify --expbuf-device Total: 46, Succeeded: 46, Failed: 0, Warnings: 0 ------------------------------------------------------------------------------- [1] https://source.codeaurora.org/quic/la/kernel/msm-3.10/ [2] https://git.linuxtv.org//v4l-utils.git [3] http://git.ideasonboard.org/yavta.git [4] https://git.linuxtv.org/sailus/media_tree.git/commit/?h=packed12-postponed&id=549c02da6eed8dc4566632a9af9233bf99ba99d8 Todor Tomov (19): doc: DT: camss: Binding document for Qualcomm Camera subsystem driver MAINTAINERS: Add Qualcomm Camera subsystem driver doc: media/v4l-drivers: Add Qualcomm Camera Subsystem driver document media: camss: Add CSIPHY files media: camss: Add CSID files media: camss: Add ISPIF files media: camss: Add VFE files media: camss: Add files which handle the video device nodes media: camms: Add core files media: camss: Enable building camss: vfe: Format conversion support using PIX interface doc: media/v4l-drivers: Qualcomm Camera Subsystem -
