The driver implements a Memory2Memory VB2 V4L2 streaming device permitting: - 0, 90, 180, 270deg rotation - horizontal/vertical flipping - source cropping - destination compositing - 32bit/24bit/16bit format conversion This adds the support for the GE2D version found in the AXG SoCs Family. The missing features are: - Source scaling - Colorspace conversion - Advanced alpha blending & blitting options Dependencies: - Patches 1-3: None - Patch 4: https://lkml.kernel.org/r/20200915124553.8056-1-narmstrong@baylibre.com (applied for 5.11) Changes since v1: - Rebased on v5.10-rc1 / # v4l2-compliance -s v4l2-compliance SHA: ea16a7ef13a902793a5c2626b0cefc4d956147f3, 64 bits, 64-bit time_t Compliance test for meson-ge2d device /dev/video0: Driver Info: Driver name : meson-ge2d Card type : meson-ge2d Bus info : platform:meson-ge2d Driver version : 5.9.0 Capabilities : 0x84208000 Video Memory-to-Memory Streaming Extended Pix Format Device Capabilities Device Caps : 0x04208000 Video Memory-to-Memory Streaming Extended Pix Format Required ioctls: test VIDIOC_QUERYCAP: OK Allow for multiple opens: test second /dev/video0 open: OK test VIDIOC_QUERYCAP: OK test VIDIOC_G/S_PRIORITY: OK test for unlimited opens: OK test invalid ioctls: OK Debug ioctls: test VIDIOC_DBG_G/S_REGISTER: OK test VIDIOC_LOG_STATUS: OK (Not Supported) Input ioctls: test VIDIOC_G/S_TUNER/ENUM_FREQ_BANDS: OK (Not Supported) test VIDIOC_G/S_FREQUENCY: OK (Not Supported) test VIDIOC_S_HW_FREQ_SEEK: OK (Not Supported) test VIDIOC_ENUMAUDIO: OK (Not Supported) test VIDIOC_G/S/ENUMINPUT: OK (Not Supported) test VIDIOC_G/S_AUDIO: OK (Not Supported) Inputs: 0 Audio Inputs: 0 Tuners: 0 Output ioctls: test VIDIOC_G/S_MODULATOR: OK (Not Supported) test VIDIOC_G/S_FREQUENCY: OK (Not Supported) test VIDIOC_ENUMAUDOUT: OK (Not Supported) test VIDIOC_G/S/ENUMOUTPUT: OK (Not Supported) test VIDIOC_G/S_AUDOUT: OK (Not Supported) Outputs: 0 Audio Outputs: 0 Modulators: 0 Input/Output configuration ioctls: test VIDIOC_ENUM/G/S/QUERY_STD: OK (Not Supported) test VIDIOC_ENUM/G/S/QUERY_DV_TIMINGS: OK (Not Supported) test VIDIOC_DV_TIMINGS_CAP: OK (Not Supported) test VIDIOC_G/S_EDID: OK (Not Supported) Control ioctls: test VIDIOC_QUERY_EXT_CTRL/QUERYMENU: OK test VIDIOC_QUERYCTRL: OK test VIDIOC_G/S_CTRL: OK test VIDIOC_G/S/TRY_EXT_CTRLS: OK test VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT: OK test VIDIOC_G/S_JPEGCOMP: OK (Not Supported) Standard Controls: 4 Private Controls: 0 Format ioctls: test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: OK test VIDIOC_G/S_PARM: OK (Not Supported) test VIDIOC_G_FBUF: OK (Not Supported) test VIDIOC_G_FMT: OK test VIDIOC_TRY_FMT: OK test VIDIOC_S_FMT: OK test VIDIOC_G_SLICED_VBI_CAP: OK (Not Supported) test Cropping: OK test Composing: OK test Scaling: OK (Not Supported) Codec ioctls: test VIDIOC_(TRY_)ENCODER_CMD: OK (Not Supported) test VIDIOC_G_ENC_INDEX: OK (Not Supported) test VIDIOC_(TRY_)DECODER_CMD: OK (Not Supported) Buffer ioctls: test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF: OK test VIDIOC_EXPBUF: OK test Requests: OK (Not Supported) Test input 0: Streaming ioctls: test read/write: OK (Not Supported) test blocking wait: OK Video Capture: Captured 58 buffers test MMAP (no poll): OK Video Capture: Captured 58 buffers test MMAP (select): OK Video Capture: Captured 58 buffers test MMAP (epoll): OK test USERPTR (no poll): OK (Not Supported) test USERPTR (select): OK (Not Supported) test DMABUF: Cannot test, specify --expbuf-device Total for meson-ge2d device /dev/video0: 52, Succeeded: 52, Failed: 0, Warnings: 0 Neil Armstrong (4): dt-bindings: media: Add bindings for the Amlogic GE2D Accelerator Unit media: meson: Add M2M driver for the Amlogic GE2D Accelerator Unit MAINTAINERS: Add myself as maintainer of the Amlogic GE2D driver arm64: dts: meson-axg: add GE2D node .../bindings/media/amlogic,axg-ge2d.yaml | 47 + MAINTAINERS | 9 + arch/arm64/boot/dts/amlogic/meson-axg.dtsi | 9 + drivers/media/platform/Kconfig | 13 + drivers/media/platform/Makefile | 2 + drivers/media/platform/meson/ge2d/Makefile | 3 + drivers/media/platform/meson/ge2d/ge2d-regs.h | 360 ++++++ drivers/media/platform/meson/ge2d/ge2d.c | 1105 +++++++++++++++++ 8 files changed, 1548 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/amlogic,axg-ge2d.yaml create mode 100644 drivers/media/platform/meson/ge2d/Makefile create mode 100644 drivers/media/platform/meson/ge2d/ge2d-regs.h create mode 100644 drivers/media/platform/meson/ge2d/ge2d.c
