This increases type safety and will ease extending\nformat descriptions.\n\nThe series starts by importing a new version of the kernel headers, and\nadding a (for now) local DRM_FORMAT_MJPEG FourCC. Patch 4/7 and 5/7 then\nintroduce the new PixelFormat type and use it through the code. Patches\n6/7 and 7/7 finally switch the PixelFormat numerical value to use DRM\nFourCC instead of V4L2 FourCC.\n\nThank you Jacopo for your initial work.\n\nJacopo Mondi (7):\n include: linux: Update headers to Linux v5.2\n include: linux: Import DRM/KMS headers from Linux v5.2\n include: drm_fourcc: Add Motion-JPEG FourCC\n libcamera: Define a PixelFormat type for application-facing formats\n libcamera: stream: Use the newly defined PixelFormat\n libcamera: v4l2_videodevice: Add PixelFormat conversion\n libcamera: Switch PixelFormat to DRM FourCC values\n\n include/libcamera/meson.build | 1 +\n include/libcamera/pixelformats.h | 18 +\n include/libcamera/stream.h | 13 +-\n include/linux/drm.h | 1042 ++++++++++++++++++++++\n include/linux/drm_fourcc.h | 765 ++++++++++++++++\n include/linux/drm_mode.h | 1032 +++++++++++++++++++++\n include/linux/media-bus-format.h | 4 +-\n include/linux/media.h | 27 +-\n include/linux/v4l2-controls.h | 29 +\n include/linux/videodev2.h | 31 +-\n src/libcamera/include/v4l2_videodevice.h | 5 +\n src/libcamera/meson.build | 1 +\n src/libcamera/pipeline/ipu3/ipu3.cpp | 7 +-\n src/libcamera/pipeline/rkisp1/rkisp1.cpp | 25 +-\n src/libcamera/pipeline/uvcvideo.cpp | 4 +-\n src/libcamera/pipeline/vimc.cpp | 15 +-\n src/libcamera/pixelformats.cpp | 28 +\n src/libcamera/stream.cpp | 17 +-\n src/libcamera/v4l2_videodevice.cpp | 141 +++\n src/qcam/format_converter.cpp | 30 +-\n test/camera/buffer_import.cpp | 17 +-\n 21 files changed, 3177 insertions(+), 75 deletions(-)\n create mode 100644 include/libcamera/pixelformats.h\n create mode 100644 include/linux/drm.h\n create mode 100644 include/linux/drm_fourcc.h\n create mode 100644 include/linux/drm_mode.h\n create mode 100644 src/libcamera/pixelformats.cpp"}
