The CSI-2 receiver (CRU) saves\nimages to memory and the ISP is fed through a dedicated DMA engine that\nprovides memory interfacing capabilities.\n\nThe series starts by adding support for the RZG2LCRU class (named after\nthe media device name) and then plumbs memory-to-memory operations in\nthe pipeline handler.\n\nTested on RZ/V2H(P) EVK with imx708 camera sensor.\n\nDan, could you re-test with Inline mode please ?\nI should have collected your fix that restored proper operations with\nInline.\n\nSigned-off-by: Jacopo Mondi \n---\nChanges in v5:\n- Use overloaded std::visit when possible\n- Adjust indentation\n\nChanges in v4:\n- Move the overloaded visitor helper to utils.h\n\nChanges in v3:\n- Drop dynamic polymorphism and use overloaded visitor in\n MaliC55CameraData. The result is neater in my opinion.\n- Address Barnabas' comments I missed in v2\n\nChanges in v2:\n- Almost a complete rework of the CameraData which is now a class\n hierarchy. I'm not sure the result is that much cleaner, but hey, I'm\n using templates and pattern with weird names, so it ought be better\n for sure\n\n---\nDaniel Scally (3):\n libcamera: mali-c55: Add RZG2LCRU class\n libcamera: mali-c55: Register memory input camera\n libcamera: mali-c55: Implement capture for memory-to-memory\n\nJacopo Mondi (4):\n libcamera: utils: Add overloaded visitor helpers\n libcamera: mali-c55: Split TPG and Inline camera handling\n libcamera: mali-c55: Configure camera in memory-to-memory\n libcamera: mali-c55: Fix sensor size computation\n\n include/libcamera/base/utils.h | 7 +\n src/libcamera/base/utils.cpp | 35 ++\n src/libcamera/pipeline/mali-c55/mali-c55.cpp | 623 ++++++++++++++++++++------\n src/libcamera/pipeline/mali-c55/meson.build | 3 +-\n src/libcamera/pipeline/mali-c55/rzg2l-cru.cpp | 260 +++++++++++\n src/libcamera/pipeline/mali-c55/rzg2l-cru.h | 73 +++\n src/libcamera/pipeline/virtual/virtual.cpp | 10 +-\n 7 files changed, 867 insertions(+), 144 deletions(-)\n---\nbase-commit: 02277d4c1a5ae7fee582f635936877435a12db64\nchange-id: 20251205-mali-cru-e212f8ab332e\n\nBest regards,"}
