Additional information about the pipeline\nhandler itself can be found in patch 8/8.\n\nPatch 1/8 adds a V4L2 API extension required for pipeline\nauto-configuration, which has been posted as an RFC but not merged in\nthe mainline kernel yet. Patches 2/8 to 7/8 than add a new utility\nfunction and small extensions to the V4L2-related classes. Patch 8/8\nadds the new simple pipeline handler.\n\nThe code has been tested on an i.MX7 platform with a greyscale sensor.\nI've kept sun6i-csi from Martijn's work in the list of supported\ndrivers, but supporting that platform will require extending the\ncorresponding driver to support the VIDIOC_ENUM_FMT extension. Once\ndone, if all goes well, the platform should work out of the box.\n\nBenjamin, Mickael, this is meant to be compatible with the stm32 and\nqcom-camss that you have previously submitted pipeline handlers for. You\nwill need to add the respective drivers to the drivers array in\nSimplePipelineHandler::match(), and, as for sun6i-csi, you will need to\nimplement support for the VIDIOC_ENUM_FMT extension, which should be\nfairly easy.\n\nLaurent Pinchart (7):\n [DNI] include: linux: Extend VIDIOC_ENUM_FMT to support MC-centric\n devices\n libcamera: utils: Add string join function\n libcamera: v4l2_subdevice: Extend [gs]etFormat() to specify format\n type\n libcamera: v4l2_videodevice: Support filtering formats by media bus\n code\n libcamera: v4l2_videodevice: Expose the device capabilities\n libcamera: v4l2_videodevice: Downgrade 4CC conversion errors to\n warnings\n libcamera: v4l2_videodevice: Map V4L2_PIX_FMT_GREY to DRM FourCC\n\nMartijn Braam (1):\n libcamera: pipeline: Add a simple pipeline handler\n\n include/linux/videodev2.h | 4 +-\n src/libcamera/include/utils.h | 44 ++\n src/libcamera/include/v4l2_subdevice.h | 11 +-\n src/libcamera/include/v4l2_videodevice.h | 6 +-\n src/libcamera/pipeline/meson.build | 1 +\n src/libcamera/pipeline/simple/meson.build | 3 +\n src/libcamera/pipeline/simple/simple.cpp | 693 ++++++++++++++++++++++\n src/libcamera/utils.cpp | 16 +\n src/libcamera/v4l2_subdevice.cpp | 23 +-\n src/libcamera/v4l2_videodevice.cpp | 36 +-\n test/utils.cpp | 7 +-\n 11 files changed, 828 insertions(+), 16 deletions(-)\n create mode 100644 src/libcamera/pipeline/simple/meson.build\n create mode 100644 src/libcamera/pipeline/simple/simple.cpp"}
