As a consequence, when in the need to de-serialize a ControlInfoMap all the ControlId it contains are created by the deserializer instance, not being able to discern if the controls the ControlIdMap refers to are the global libcamera controls (and proeprties) or instances local to the V4L2 device that has first initialized the controls. As a consequence the ControlId stored in a de-serialized map will always be newly created entities, preventing lookup by ControlId reference on a de-serialized ControlInfoMap. In order to make it possible to use globally available ControlId instances whenever possible, create ControlInfoMap with a reference to an externally allocated ControlIdMap instead of generating one internally. Has a consequence the class constructors take and additional argument, which might be not pleaseant to type in, but enforces the concepts that ControlInfoMap should be created with controls part of the same id map. As the ControlIdMap the ControlInfoMap refers to need to be allocated externally: - Use the globally available controls::controls (or properties::properties) id map when referring to libcamera controls - The V4L2 device that creates ControlInfoMap by parsing the device's controls has to allocate a ControlIdMap and ties its lifetime management to the its own one - The ControlSerializer that de-serializes a ControlInfoMap has to create and store the ControlIdMap the de-serialized info map refers to Signed-off-by: Jacopo Mondi Reviewed-by: Paul Elder --- include/libcamera/controls.h | 13 ++- .../libcamera/internal/control_serializer.h | 1 + include/libcamera/internal/v4l2_device.h | 1 + include/libcamera/ipa/raspberrypi.h | 40 ++++----- src/libcamera/control_serializer.cpp | 11 ++- src/libcamera/controls.cpp | 82 ++++--------------- src/libcamera/pipeline/ipu3/ipu3.cpp | 3 +- src/libcamera/pipeline/rkisp1/rkisp1.cpp | 3 +- src/libcamera/pipeline/uvcvideo/uvcvideo.cpp | 2 +- src/libcamera/pipeline/vimc/vimc.cpp | 2 +- src/libcamera/v4l2_device.cpp | 3 +- .../ipa_data_serializer_test.cpp | 4 +- 12 files changed, 59 insertions(+), 106 deletions(-) diff --git a/include/libcamera/controls.h b/include/libcamera/controls.h index 1bc958a43b22..4a2cdb335870 100644 --- a/include/libcamera/controls.h +++ b/include/libcamera/controls.h @@ -306,12 +306,11 @@ public: ControlInfoMap() = default;
