I'm sure I have missed something anyhow...\n\nIt's mostly about using 'const' a lot more for values returned by reference\nby getter functions, a more extensive use of 'auto' keyboard to shorten\niterators declarations and a few cosmetic changes.\n\nBoth branches (v1 and v2) are available for comparison\n(jmondi/master/media_device_v1 and jmondi/master/media_device_v2) and a diff\nis collected here: https://paste.debian.net/1057251/\n\nOn top of the first two patches that were included in v1, I have added what\nI proposed in the review of Niklas' series: a MediaDeviceDesc object and a\nmatch function to be added to the MediaDevice. Niklas, what do you think\nabout this? Does this help clarifying the proposal I made in the review\ncomments? (those patches are now broken out to eases discussion and review,\nbut will be ideally squashed on the [02/04] later).\n\nI have some private tests for IPU3, and the matching code looks like the\nfollowing:\n\n\tMediaDeviceDesc cio2_desc(\"ipu3-cio2\");\n\tcio2_desc.addEntity(\"ipu3-csi2 0\");\n\tcio2_desc.addEntity(\"ipu3-cio2 0\");\n\tcio2_desc.addEntity(\"ipu3-csi2 1\");\n\tcio2_desc.addEntity(\"ipu3-cio2 1\");\n\tcio2_desc.addEntity(\"ipu3-csi2 2\");\n\tcio2_desc.addEntity(\"ipu3-cio2 2\");\n\tcio2_desc.addEntity(\"ipu3-csi2 3\");\n\tcio2_desc.addEntity(\"ipu3-cio2 3\");\n\tcio2_desc.addEntity(\"ov13858 2-0010\");\n\tcio2_desc.addEntity(\"ov5670 4-0036\");\n\n\tbool match = cio2.match(cio2_desc);\n\tif (match) {\n\t\tLOG(Info) << \"CIO2 matched\";\n\t} else {\n\t\tLOG(Error) << \"Cannot match CIO2 with the provided desc\";\n\t\treturn -1;\n\t}\n\nIf we adopt something like this, in place of cio2.match() we would have a\nMediaEnumerator, as proposed by Niklas, but the idea stays the same: is the\nMediaDevice that matches the MediaDeviceDesc, and the MediaEnumerator receives\na MediaDeviceDesc and tries it on all its open MediaDevices.\n\nThanks\n j\n\nv1 -> v2:\n- diff collected here: https://paste.debian.net/1057251/\n- patches 3 and 4 are new, broken out for review, to be squashed later.\n\nJacopo Mondi (4):\n libcamera: Add MediaObject class hierarchy\n libcamera: Add MediaDevice class\n libcamera: media device: Add MediaDeviceDesc\n libcamera: media device: Add 'match()' method\n\n src/libcamera/include/media_device.h | 115 +++++\n src/libcamera/include/media_object.h | 117 +++++\n src/libcamera/media_device.cpp | 615 +++++++++++++++++++++++++++\n src/libcamera/media_object.cpp | 302 +++++++++++++\n src/libcamera/meson.build | 2 +\n 5 files changed, 1151 insertions(+)\n create mode 100644 src/libcamera/include/media_device.h\n create mode 100644 src/libcamera/include/media_object.h\n create mode 100644 src/libcamera/media_device.cpp\n create mode 100644 src/libcamera/media_object.cpp\n\n--\n2.20.1"}
