This series aim to add the second VPU (aka G2) and provide basic HEVC decoding support. To be able to decode HEVC it is needed to add/update some of the structures in the uapi. In addition of them one HANTRO dedicated control is required to inform the driver of the numbre of bits to skip at the beginning of the slice header. The hardware require to allocate few auxiliary buffers to store the references frame or tile size data. The driver has been tested with fluster test suite stream. For example with this command: ./fluster.py run -ts JCT-VC-HEVC_V1 -d GStreamer-H.265-V4L2SL-Gst1.0 This series depends of the reset rework posted here: https://www.spinics.net/lists/arm-kernel/msg875766.html Finally the both VPUs will have a node the device-tree and be independent from v4l2 point of view. A branch with all the dev is available here: https://gitlab.collabora.com/benjamin.gaignard/for-upstream/-/commits/upstream_g2_v2 version 2: - remove all change related to scaling - squash commits to a coherent split - be more verbose about the added fields - fix the comments done by Ezequiel about dma_alloc_coherent usage - fix Dan's comments about control copy, reverse the test logic in tile_buffer_reallocate, rework some goto and return cases. - be more verbose about why I change the bindings - remove all sign-off expect mime since it is confusing - remove useless clocks in VPUs nodes Benjamin Benjamin Gaignard (9): media: hevc: Modify structures to follow H265 ITU spec media: hantro: Define HEVC codec profiles and supported features media: hantro: Add a field to distinguish the hardware versions media: uapi: Add a control for HANTRO driver media: hantro: Introduce G2/HEVC decoder media: hantro: handle V4L2_PIX_FMT_HEVC_SLICE control media: hantro: IMX8M: add variant for G2/HEVC codec dt-bindings: media: nxp,imx8mq-vpu: Update bindings arm64: dts: imx8mq: Add node to G2 hardware .../bindings/media/nxp,imx8mq-vpu.yaml | 54 +- arch/arm64/boot/dts/freescale/imx8mq.dtsi | 41 +- drivers/media/v4l2-core/v4l2-ctrls.c | 26 +- drivers/staging/media/hantro/Makefile | 2 + drivers/staging/media/hantro/hantro.h | 34 +- drivers/staging/media/hantro/hantro_drv.c | 103 +++ .../staging/media/hantro/hantro_g2_hevc_dec.c | 587 ++++++++++++++++++ drivers/staging/media/hantro/hantro_g2_regs.h | 198 ++++++ drivers/staging/media/hantro/hantro_hevc.c | 321 ++++++++++ drivers/staging/media/hantro/hantro_hw.h | 48 ++ .../staging/media/hantro/hantro_postproc.c | 17 + drivers/staging/media/hantro/hantro_v4l2.c | 1 + drivers/staging/media/hantro/imx8m_vpu_hw.c | 95 ++- drivers/staging/media/sunxi/cedrus/cedrus.c | 6 + drivers/staging/media/sunxi/cedrus/cedrus.h | 1 + .../staging/media/sunxi/cedrus/cedrus_dec.c | 2 + .../staging/media/sunxi/cedrus/cedrus_h265.c | 6 +- include/media/hevc-ctrls.h | 45 +- include/uapi/linux/hantro-v4l2-controls.h | 20 + include/uapi/linux/v4l2-controls.h | 5 + 20 files changed, 1557 insertions(+), 55 deletions(-) create mode 100644 drivers/staging/media/hantro/hantro_g2_hevc_dec.c create mode 100644 drivers/staging/media/hantro/hantro_g2_regs.h create mode 100644 drivers/staging/media/hantro/hantro_hevc.c create mode 100644 include/uapi/linux/hantro-v4l2-controls.h
