Only patch 1/2 remains as a drive-by\nimprovement from v2, and of course patch 2/2 that performs to actual\nconversion to Span.\n\nWith FrameBuffer::planes() returning a span, multiple callers have to be\nmodified through libcamera. While there is no actual change to test\napplications thanks for previous refactoring that made application code\nAPI-compatible with this change, the patch series still changes the\nlibcamera ABI and API, requiring recompilation and possibly code\nchanges.\n\nLaurent Pinchart (2):\n pipelines: Use lambda functions to factor out buffer mapping code\n libcamera: framebuffer: Replace vector with span in constructor\n\n include/libcamera/framebuffer.h | 4 +--\n include/libcamera/internal/framebuffer.h | 3 +-\n .../mm/cros_frame_buffer_allocator.cpp | 2 +-\n .../mm/generic_frame_buffer_allocator.cpp | 2 +-\n src/libcamera/framebuffer.cpp | 10 +++----\n src/libcamera/pipeline/ipu3/ipu3.cpp | 20 ++++++++-----\n src/libcamera/pipeline/mali-c55/mali-c55.cpp | 30 +++++++++++--------\n src/libcamera/pipeline/rkisp1/rkisp1.cpp | 26 ++++++++--------\n .../pipeline/rpi/common/pipeline_base.cpp | 6 ++--\n src/libcamera/pipeline/vimc/vimc.cpp | 5 +++-\n src/libcamera/pipeline/virtual/virtual.cpp | 3 +-\n src/libcamera/v4l2_videodevice.cpp | 6 ++--\n 12 files changed, 68 insertions(+), 49 deletions(-)\n\n\nbase-commit: baea40a8a5dddbad3cf6398aa8ce248e4547c955\n--\nRegards,\n\nLaurent Pinchart" }
