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. 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 --- Based on v5.0-rc1 and these series: device tree: http://lists.infradead.org/pipermail/linux-mediatek/2019-February/017570.html clock control: http://lists.infradead.org/pipermail/linux-mediatek/2019-February/017320.html system control processor (SCP): http://lists.infradead.org/pipermail/linux-mediatek/2019-February/017774.html global command engine (GCE): http://lists.infradead.org/pipermail/linux-mediatek/2019-January/017143.html --- daoyuan huang (4): dt-binding: mt8183: Add Mediatek MDP3 dt-bindings dts: arm64: mt8183: Add Mediatek MDP3 nodes media: platform: Add Mediatek MDP3 driver KConfig media: platform: mtk-mdp3: Add Mediatek MDP3 driver .../bindings/media/mediatek,mt8183-mdp3.txt | 217 +++ arch/arm64/boot/dts/mediatek/mt8183.dtsi | 173 +++ drivers/media/platform/Kconfig | 18 + drivers/media/platform/Makefile | 2 + drivers/media/platform/mtk-mdp3/Makefile | 9 + drivers/media/platform/mtk-mdp3/isp_reg.h | 38 + .../media/platform/mtk-mdp3/mdp-platform.h | 67 + .../media/platform/mtk-mdp3/mdp_reg_ccorr.h | 76 + .../media/platform/mtk-mdp3/mdp_reg_rdma.h | 207 +++ drivers/media/platform/mtk-mdp3/mdp_reg_rsz.h | 110 ++ .../media/platform/mtk-mdp3/mdp_reg_wdma.h | 126 ++ .../media/platform/mtk-mdp3/mdp_reg_wrot.h | 116 ++ .../media/platform/mtk-mdp3/mmsys_config.h | 189 +++ drivers/media/platform/mtk-mdp3/mmsys_mutex.h | 36 + .../media/platform/mtk-mdp3/mmsys_reg_base.h | 39 + drivers/media/platform/mtk-mdp3/mtk-img-ipi.h | 282 ++++ .../media/platform/mtk-mdp3/mtk-mdp3-cmdq.c | 442 ++++++ .../media/platform/mtk-mdp3/mtk-mdp3-cmdq.h | 57 + .../media/platform/mtk-mdp3/mtk-mdp3-comp.c | 1325 +++++++++++++++++ .../media/platform/mtk-mdp3/mtk-mdp3-comp.h | 177 +++ .../media/platform/mtk-mdp3/mtk-mdp3-core.c | 256 ++++ .../media/platform/mtk-mdp3/mtk-mdp3-core.h | 88 ++ .../media/platform/mtk-mdp3/mtk-mdp3-m2m.c | 823 ++++++++++ .../media/platform/mtk-mdp3/mtk-mdp3-m2m.h | 52 + .../media/platform/mtk-mdp3/mtk-mdp3-regs.c | 757 ++++++++++ .../media/platform/mtk-mdp3/mtk-mdp3-regs.h | 386 +++++ .../media/platform/mtk-mdp3/mtk-mdp3-vpu.c | 277 ++++ .../media/platform/mtk-mdp3/mtk-mdp3-vpu.h | 90 ++ 28 files changed, 6435 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/mediatek,mt8183-mdp3.txt create mode 100644 drivers/media/platform/mtk-mdp3/Makefile create mode 100644 drivers/media/platform/mtk-mdp3/isp_reg.h create mode 100644 drivers/media/platform/mtk-mdp3/mdp-platform.h create mode 100644 drivers/media/platform/mtk-mdp3/mdp_reg_ccorr.h create mode 100644 drivers/media/platform/mtk-mdp3/mdp_reg_rdma.h create mode 100644 drivers/media/platform/mtk-mdp3/mdp_reg_rsz.h create mode 100644 drivers/media/platform/mtk-mdp3/mdp_reg_wdma.h create mode 100644 drivers/media/platform/mtk-mdp3/mdp_reg_wrot.h create mode 100644 drivers/media/platform/mtk-mdp3/mmsys_config.h create mode 100644 drivers/media/platform/mtk-mdp3/mmsys_mutex.h create mode 100644 drivers/media/platform/mtk-mdp3/mmsys_reg_base.h create mode 100644 drivers/media/platform/mtk-mdp3/mtk-img-ipi.h create mode 100644 drivers/media/platform/mtk-mdp3/mtk-mdp3-cmdq.c create mode 100644 drivers/media/platform/mtk-mdp3/mtk-mdp3-cmdq.h create mode 100644 drivers/media/platform/mtk-mdp3/mtk-mdp3-comp.c create mode 100644 drivers/media/platform/mtk-mdp3/mtk-mdp3-comp.h create mode 100644 drivers/media/platform/mtk-mdp3/mtk-mdp3-core.c create mode 100644 drivers/media/platform/mtk-mdp3/mtk-mdp3-core.h create mode 100644 drivers/media/platform/mtk-mdp3/mtk-mdp3-m2m.c create mode 100644 drivers/media/platform/mtk-mdp3/mtk-mdp3-m2m.h create mode 100644 drivers/media/platform/mtk-mdp3/mtk-mdp3-regs.c create mode 100644 drivers/media/platform/mtk-mdp3/mtk-mdp3-regs.h create mode 100644 drivers/media/platform/mtk-mdp3/mtk-mdp3-vpu.c create mode 100644 drivers/media/platform/mtk-mdp3/mtk-mdp3-vpu.h -- 2.18.0
