As of today you should see something like this: $ v4l2-compliance --version v4l2-compliance 1.23.0-4922, 64 bits, 64-bit time_t v4l2-compliance SHA: 6de743337007 2022-04-07 11:29:29 And running 'v4l2-compliance -d 0' should show that SHA as well. The compliance test of a driver must always use the latest v4l2-compliance compiled from the repository, that way I know all the latest tests are run.

This patchset depends on the series "imx8mp: Add media block control"[1] and "i.MX8MP GPC and blk-ctrl"[2] which provide the power driver infrastructure. Previous series can now be marked as superseded. v1: https://patchwork.linuxtv.org/project/linux-media/list/?series=7443 v2: https://patchwork.linuxtv.org/project/linux-media/list/?series=7472 v3: https://patchwork.linuxtv.org/project/linux-media/list/?series=7473 Patches [1-3/9] add support for dynamic array control imported from the "Move HEVC stateless controls out of staging"[3] currently under review. Patches [4-7/9] document the driver interfaces, and export its v4l2 custom control to uapi headers. Patches [8/9] adds the v4l2 m2m driver. Patches [9/9] adds the driver to MAINTAINERS. The patch baseline is linuxtv-tree/master. The Vivante DW100 Dewarp Engine, found on i.MX8MP SoC, provides high-performance dewarp processing for the correction of the distortion that is introduced in images produced by fisheye and wide angle lenses. The engine can be used for accelerating scaling, cropping and pixel format conversion operations independently of the dewarping feature. A script example [4] has been published to generate the dewarping blob from outgoing openCV 3d calibration process parameters. This scrict can generate identity map with h/v flip, dewarping and stereo rectification mappings. The driver has been tested with: - v4l2-ctl (from master with [6]) for testing pixel format conversion, scaling and crop features using builtin driver identity map. - OpenCV stereo application using dedicated dw100 openCV module [5] to implement stereo rectification stage. - GStreamer v4l2convert (patched to support dewarping blob map injection) - v4l2-compliance (test report added after changelog) [1] https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=626781 [2] https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=618869 [3] https://patchwork.linuxtv.org/project/linux-media/list/?series=7418 [4] https://github.com/NXPmicro/vtec-cv/tree/main/bin [5] https://github.com/NXPmicro/vtec-opencv [6] https://patchwork.linuxtv.org/project/linux-media/list/?series=7595 --- Changelog: v4: - Move dw100 driver to NXP platform media drivers folder - Change dt compatible string to "nxp,imx8mp-dw100" - Rename V4L2_CID_DW100_MAPPING to V4L2_CID_DW100_DEWARPING_16x16_VERTEX_MAP - Add more verbose description of V4L2_CID_DW100_DEWARPING_16x16_VERTEX_MAP - Handle v4l2 controls as an array in driver. v3: - Fix incorrect i.MX8MP Reference Manual link in documentation v2: - Fix yaml dt-bindings errors - Drop assigned-clocks properties from dt-bindings example - Add dw100 driver documentation - Rework V4L2 LUT assignment with v4l2 dynamic array control - Rename V4L2_CID_DW100_LUT to V4L2_CID_DW100_MAPPING - Export V4L2_CID_DW100_MAPPING to kernel headers Hans Verkuil (3): videodev2.h: add V4L2_CTRL_FLAG_DYNAMIC_ARRAY v4l2-ctrls: add support for dynamically allocated arrays. vivid: add dynamic array test control Xavier Roumegue (6): media: Documentation: dw100: Add user documentation for the DW100 driver media: v4l: uapi: Add user control base for DW100 controls media: uapi: Add a control for DW100 driver media: dt-bindings: media: Add i.MX8MP DW100 binding media: dw100: Add i.MX8MP dw100 dewarper driver media: MAINTAINERS: add entry for i.MX8MP DW100 v4l2 mem2mem driver .../devicetree/bindings/media/nxp,dw100.yaml | 69 + .../userspace-api/media/drivers/dw100.rst | 35 + .../userspace-api/media/drivers/index.rst | 1 + .../media/v4l/vidioc-queryctrl.rst | 8 + MAINTAINERS | 9 + drivers/media/platform/nxp/Kconfig | 1 + drivers/media/platform/nxp/Makefile | 1 + drivers/media/platform/nxp/dw100/Kconfig | 16 + drivers/media/platform/nxp/dw100/Makefile | 3 + drivers/media/platform/nxp/dw100/dw100.c | 1763 +++++++++++++++++ drivers/media/platform/nxp/dw100/dw100_regs.h | 118 ++ .../media/test-drivers/vivid/vivid-ctrls.c | 15 + drivers/media/v4l2-core/v4l2-ctrls-api.c | 103 +- drivers/media/v4l2-core/v4l2-ctrls-core.c | 182 +- drivers/media/v4l2-core/v4l2-ctrls-priv.h | 3 +- drivers/media/v4l2-core/v4l2-ctrls-request.c | 13 +- include/media/v4l2-ctrls.h | 42 +- include/uapi/linux/dw100.h | 11 + include/uapi/linux/v4l2-controls.h | 6 +- include/uapi/linux/videodev2.h | 1 + 20 files changed, 2328 insertions(+), 72 deletions(-) create mode 100644 Documentation/devicetree/bindings/media/nxp,dw100.yaml create mode 100644 Documentation/userspace-api/media/drivers/dw100.rst create mode 100644 drivers/media/platform/nxp/dw100/Kconfig create mode 100644 drivers/media/platform/nxp/dw100/Makefile create mode 100644 drivers/media/platform/nxp/dw100/dw100.c create mode 100644 drivers/media/platform/nxp/dw100/dw100_regs.h create mode 100644 include/uapi/linux/dw100.h ============ Compliance ============ #
