Change since v11: - Rebase on linux-next tag:next-20220316 - Depend on: [1] https://patchwork.kernel.org/project/linux-mediatek/list/?series=624281 - Remove redundant hardware index in data-binding suggested by Rob Herring. - Referring to Rob Herring's suggestion to improve some descriptions in the RDMA dt-binding - Move MDP3 file folder from "./drive/media/platform/mtk-mdp3" to "./driver/media/platform/mediatek/mdp3" - Fixed the V4L2 and MDP color format mapping error in RGB565 which checked by Benjamin Gaignard Change since v10: - The routing table needs to be discarded, and the calculation result on the SCP side is used to write a suitable mux setting for 1 input port and 2 output ports. - Adjust dts parsing flow to remove redundant HW IDs. - Fix memory leak caused by no free path information in function "mdp_cmdq_send". Change since v9: - Keep only the MDP3 driver patches and split the remaining mmsys and mutex patches into another mail. - Move mutex mod settings to corresponding driver and make relevant adjustments for this in MDP3 driver. - Fix compile warning reported by kernel test robot. Change since v8: - Rebase on v5.16-rc2. - Refer to Angelo's suggestion, adjust the register writing format to increase readability and significance. - Refer to Angelo's suggestion, adjust or reduce inappropriate debugging messages. - Refer to Rob Herring's suggestion to correct the the binding file to make it with the specification. - Fix compile warning reported by kernel test robot. Change since v7: - Rebase on v5.15-rc6. - Revise several V4L2 M2M settings to pass v4l2-compliance test. - Integrate those same component dt-binding documents of DRM and MDP, and move them under the MMSYS domain. - Split MMSYS and MUTEX into two different files according to their functional properties. Changes since v6: - Refactor GCE event to corresponding node. - Fix dt_binding_check fail. - Fix compilation errors. Changes since v5: - Rebase on v5.14-rc6. - Move MMSYS/Mutex settings to corresponding driver. - Revise the software license description and copyright. - Remove unnecessary enum. or definitions. - Optimize platform/chip definition conditions. - Use general printing functions instead of MDP3 private ones. - Fix compile warning. Changes since v4: - Rebase on v5.13-rc1. - Remove the CMDQ flush flow to match the CMDQ API change. - Integrate four of MDP's direct-link subcomponents into MDP controller node from syscon node to avoid illegal clock usage. - Rewrite dt-binding in a JSON compatible subset of YAML - Fix a bit of macro argument precedence. Changes since v3: - Rebase on v5.9-rc1. - modify code for review comment from Rob Herring, cancel multiple nodes using same register base situation. - control IOMMU port through pm runtime get/put to DMA components' device. - SCP(VPU) driver revision. - stop queuing jobs(remove flush_workqueue()) after mdp_m2m_release(). - add computation of plane address with data_offset. - fix scale ratio check issue. - add default v4l2_format setting. Changes since v2: - modify code for review comment from Tomasz Figa & Alexandre Courbot - review comment from Rob Herring will offer code revision in v4, due to it's related to device node modification, will need to modify code architecture Changes since v1: - modify code for CMDQ v3 API support - EC ipi cmd migration - fix compliance test fail item (m2m cmd with -f) due to there is two problem in runing all format(-f) cmd: 1. out of memory before test complete Due to capture buffer mmap (refcount + 1) after reqbuf but seems no corresponding munmap called before device close. There are total 12XX items(formats) in format test and each format alloc 8 capture/output buffers. 2. unceasingly captureBufs() (randomly) Seems the break statement didn't catch the count == 0 situation: In v4l2-test-buffers.cpp, function: captureBufs() ... count--; if (!node->is_m2m && !count) break; Log is as attachment I will paste the test result with problem part in another e-mail Hi, This is the first version of RFC patch for Media Data Path 3 (MDP3), MDP3 is used for scaling and color format conversion. support using GCE to write register in critical time limitation. support V4L2 m2m device control.
