After this, V4L2Controls are defined, by using a base template class\nspecialized by derived classes meant to be used to access the control value.\n\nUsing the defined data types, support to get and set a single or a list of\ncontrols is added to the V4L2base class, to be shared by both V4L2Device and\nV4L2Subdevice implementations.\n\nFinally, controls are used to set the IPU3 pipe mode, and in a final example\npatch not meant to be merged a list of control is applied to the camera sensor.\n\nTested on IPU3 Soraka, by inspecting the control values before and after running\nthe IPU3 pipeline handler.\n\nThanks\n j\n\nJacopo Mondi (6):\n libcamera: camera_sensor: Add dev() operation\n libcamera: Provide a V4L2Base class\n libcamera: Add V4L2Controls\n libcamera: v4l2_base: Add V4L2 control support\n libcamera: ipu3: Set pipe_mode based on stream configuration\n [HACK] ipu3: Set and get a few sensor controls\n\n src/libcamera/camera_sensor.cpp | 6 +\n src/libcamera/include/camera_sensor.h | 1 +\n src/libcamera/include/v4l2_base.h | 43 +++\n src/libcamera/include/v4l2_controls.h | 147 ++++++++++\n src/libcamera/include/v4l2_device.h | 9 +-\n src/libcamera/include/v4l2_subdevice.h | 9 +-\n src/libcamera/meson.build | 3 +\n src/libcamera/pipeline/ipu3/ipu3.cpp | 116 ++++++++\n src/libcamera/v4l2_base.cpp | 354 +++++++++++++++++++++++++\n src/libcamera/v4l2_controls.cpp | 301 +++++++++++++++++++++\n src/libcamera/v4l2_device.cpp | 13 +-\n src/libcamera/v4l2_subdevice.cpp | 12 +-\n 12 files changed, 984 insertions(+), 30 deletions(-)\n create mode 100644 src/libcamera/include/v4l2_base.h\n create mode 100644 src/libcamera/include/v4l2_controls.h\n create mode 100644 src/libcamera/v4l2_base.cpp\n create mode 100644 src/libcamera/v4l2_controls.cpp\n\n--\n2.21.0" }
