Hi Mauro, This is the cedrus Allwinner decoder driver. It is for the request_api topic branch.
Note that there is a COMPILE_TEST issue with sram functions, for that another patch is needed: https://lore.kernel.org/patchwork/patch/983848/ But that's going through another subsystem and is already queued up for 4.20. The first two patches fix two trivial sparse and smatch issues. Many, many thanks go to Paul for working on this, trying to keep up to date with the Request API changes at the same time. It was a pleasure working with you on this! I'm now using a signed tag, let me know if this works or not. Regards, Hans The following changes since commit d4215edbd4b170b207b0e5a1d8ae42fb49f5c470: media: media-request: update documentation (2018-09-11 09:58:43 -0400) are available in the Git repository at: git://linuxtv.org/hverkuil/media_tree.git tags/br-cedrus for you to fetch changes up to 615ba78ac81ce76edf5ae84981e404fd4eee3ee0: media: platform: Add Cedrus VPU decoder driver (2018-09-14 14:27:45 +0200) ---------------------------------------------------------------- Tag cedrus branch ---------------------------------------------------------------- Hans Verkuil (2): v4l2-compat-ioctl32.c: fix sparse warning v4l2-ctrls.c: fix smatch error Paul Kocialkowski (5): media: videobuf2-core: Rework and rename helper for request buffer count media: v4l: Add definitions for MPEG-2 slice format and metadata media: v4l: Add definition for the Sunxi tiled NV12 format dt-bindings: media: Document bindings for the Cedrus VPU driver media: platform: Add Cedrus VPU decoder driver Documentation/devicetree/bindings/media/cedrus.txt | 54 +++++++ Documentation/media/uapi/v4l/extended-controls.rst | 176 ++++++++++++++++++++++ Documentation/media/uapi/v4l/pixfmt-compressed.rst | 16 ++ Documentation/media/uapi/v4l/pixfmt-reserved.rst | 15 +- Documentation/media/uapi/v4l/vidioc-queryctrl.rst | 14 +- Documentation/media/videodev2.h.rst.exceptions | 2 + MAINTAINERS | 7 + drivers/media/common/videobuf2/videobuf2-core.c | 18 +-- drivers/media/common/videobuf2/videobuf2-v4l2.c | 2 +- drivers/media/v4l2-core/v4l2-compat-ioctl32.c | 1 + drivers/media/v4l2-core/v4l2-ctrls.c | 65 +++++++- drivers/media/v4l2-core/v4l2-ioctl.c | 2 + drivers/staging/media/Kconfig | 2 + drivers/staging/media/Makefile | 1 + drivers/staging/media/sunxi/Kconfig | 15 ++ drivers/staging/media/sunxi/Makefile | 1 + drivers/staging/media/sunxi/cedrus/Kconfig | 14 ++ drivers/staging/media/sunxi/cedrus/Makefile | 3 + drivers/staging/media/sunxi/cedrus/TODO | 7 + drivers/staging/media/sunxi/cedrus/cedrus.c | 431 +++++++++++++++++++++++++++++++++++++++++++++++++++++ drivers/staging/media/sunxi/cedrus/cedrus.h | 167 +++++++++++++++++++++ drivers/staging/media/sunxi/cedrus/cedrus_dec.c | 70 +++++++++ drivers/staging/media/sunxi/cedrus/cedrus_dec.h | 27 ++++ drivers/staging/media/sunxi/cedrus/cedrus_hw.c | 327 ++++++++++++++++++++++++++++++++++++++++ drivers/staging/media/sunxi/cedrus/cedrus_hw.h | 30 ++++ drivers/staging/media/sunxi/cedrus/cedrus_mpeg2.c | 246 ++++++++++++++++++++++++++++++ drivers/staging/media/sunxi/cedrus/cedrus_regs.h | 235 +++++++++++++++++++++++++++++ drivers/staging/media/sunxi/cedrus/cedrus_video.c | 542 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ drivers/staging/media/sunxi/cedrus/cedrus_video.h | 30 ++++ include/media/v4l2-ctrls.h | 18 ++- include/media/videobuf2-core.h | 4 +- include/uapi/linux/v4l2-controls.h | 65 ++++++++ include/uapi/linux/videodev2.h | 6 + 33 files changed, 2589 insertions(+), 24 deletions(-) create mode 100644 Documentation/devicetree/bindings/media/cedrus.txt create mode 100644 drivers/staging/media/sunxi/Kconfig create mode 100644 drivers/staging/media/sunxi/Makefile create mode 100644 drivers/staging/media/sunxi/cedrus/Kconfig create mode 100644 drivers/staging/media/sunxi/cedrus/Makefile create mode 100644 drivers/staging/media/sunxi/cedrus/TODO create mode 100644 drivers/staging/media/sunxi/cedrus/cedrus.c create mode 100644 drivers/staging/media/sunxi/cedrus/cedrus.h create mode 100644 drivers/staging/media/sunxi/cedrus/cedrus_dec.c create mode 100644 drivers/staging/media/sunxi/cedrus/cedrus_dec.h create mode 100644 drivers/staging/media/sunxi/cedrus/cedrus_hw.c create mode 100644 drivers/staging/media/sunxi/cedrus/cedrus_hw.h create mode 100644 drivers/staging/media/sunxi/cedrus/cedrus_mpeg2.c create mode 100644 drivers/staging/media/sunxi/cedrus/cedrus_regs.h create mode 100644 drivers/staging/media/sunxi/cedrus/cedrus_video.c create mode 100644 drivers/staging/media/sunxi/cedrus/cedrus_video.h
