It has been reworked since v2.\n\nPatch [4/6] fixes the ordering of stopping the IPA and video devices,\nwith [5/6] fixing an issue which previously completed requests (and\nassociated frame info) before all buffers had completed.\n\nFinally patch [6/6] moves an asynchronous callback out of the\nsynchronous configure() call, and into start(). This is not expected to\nbe a substantial change in functionality currently, but should be\nconsidered in follow on developments with the IPA.\n\nKieran Bingham (4):\n libcamera: buffer: Initialise status\n libcamera: pipeline: ipu3: Stop IPA before stopping devices\n libcamera: pipeline: ipu3: Do not mark metadata complete early\n ipa: ipu3: Do not set controls during configure\n\nLaurent Pinchart (2):\n utils: ipc: proxy: Assert asynchronous calls execute in the running\n state\n utils: ipc: proxy: Process pending messages\n\n include/libcamera/buffer.h | 2 +-\n src/ipa/ipu3/ipu3.cpp | 11 ++++++++---\n src/libcamera/pipeline/ipu3/ipu3.cpp | 7 ++-----\n src/libcamera/request.cpp | 9 +++++++--\n .../libcamera_templates/module_ipa_proxy.cpp.tmpl | 2 ++\n .../libcamera_templates/proxy_functions.tmpl | 6 ++++--\n 6 files changed, 24 insertions(+), 13 deletions(-)" }
