The following changes have\nbeen made over v1:\n\n- Addressed Niklas review comments.\n- Removed use of FrameBuffer::cookie() as it could be set externally.\n- Added a change to address the use of dmabufs that could have been allocated\noutside of the v4l2 device. We must still track it in the pipeline and IPA.\n\nCommit 2/10 still will need rework once Laurnet's change for IPA configuration\npassing has been merged.\n\nThanks,\nNaush\n\n\nNaushir Patuck (10):\n libcamera: pipeline: raspberrypi: Move RPiStream into a separate file\n libcamera: pipeline: ipa: raspberrypi: Rework drop frame signalling\n libcamera: pipeline: raspberrypi: Add some debug logging\n libcamera: pipeline: raspberrypi: Increase the number of RAW buffers\n libcamera: pipeline: raspberrypi: Remove const qualifier from\n RPiStream\n libcamera: pipeline: raspberrypi: Rework stream buffer logic for\n zero-copy\n libcamera: pipeline: raspberrypi: Fix bug in passing configuration to\n IPA\n libcamera: pipeline: raspberrypi: Add more robust stream buffer logic\n libcamera: pipeline: ipa: raspberrypi: Remove use of FrameBuffer\n cookie\n libcamera: pipeline: raspberrypi: Handle any externally allocated\n FrameBuffer\n\n include/libcamera/ipa/raspberrypi.h | 2 +-\n src/ipa/raspberrypi/raspberrypi.cpp | 21 +-\n .../pipeline/raspberrypi/meson.build | 1 +\n .../pipeline/raspberrypi/raspberrypi.cpp | 531 +++++++-----------\n .../pipeline/raspberrypi/rpi_stream.cpp | 219 ++++++++\n .../pipeline/raspberrypi/rpi_stream.h | 118 ++++\n 6 files changed, 552 insertions(+), 340 deletions(-)\n create mode 100644 src/libcamera/pipeline/raspberrypi/rpi_stream.cpp\n create mode 100644 src/libcamera/pipeline/raspberrypi/rpi_stream.h"}
