This series implement AV1 stateless decoder for RK3588 SoC. The harware support 8 and 10 bits bitstreams up to 7680x4320. AV1 feature like film grain or scaling are done by the postprocessor. The driver can produce NV12_4L4 and NV12 pixel formats. A native 10bits NV12_4L4 format is possible but need more investigation to be completly documented and enabled. It is based on Daniel's "[RFC,v3] media: Add AV1 uAPI" [1] patches and Sebastian's device-tree patches for RK3588.

The failing tests are: - 10bits bitstream because 10bits output formats aren't yet implemented. - the 2 tests with 2 spatial layers: few errors in luma/chroma values - tests with resolution < hardware limit (64x64) Benjamin Benjamin Gaignard (9): dt-bindings: media: rockchip-vpu: Add rk3588 vpu compatible media: verisilicon: Add AV1 decoder mode and controls media: verisilicon: Save bit depth for AV1 decoder media: verisilicon: Check AV1 bitstreams bit depth media: verisilicon: Compute motion vectors size for AV1 frames media: verisilicon: Add AV1 entropy helpers media: verisilicon: Add Rockchip AV1 decoder media: verisilicon: Add film grain feature to AV1 driver media: verisilicon: Enable AV1 decoder on rk3588 .../bindings/media/rockchip-vpu.yaml | 1 + drivers/media/platform/verisilicon/Makefile | 3 + drivers/media/platform/verisilicon/hantro.h | 5 + .../media/platform/verisilicon/hantro_drv.c | 54 + .../media/platform/verisilicon/hantro_hw.h | 102 + .../platform/verisilicon/hantro_postproc.c | 3 + .../media/platform/verisilicon/hantro_v4l2.c | 5 + .../verisilicon/rockchip_av1_entropymode.c | 4536 +++++++++++++++++ .../verisilicon/rockchip_av1_entropymode.h | 272 + .../verisilicon/rockchip_av1_filmgrain.c | 401 ++ .../verisilicon/rockchip_av1_filmgrain.h | 36 + .../verisilicon/rockchip_vpu981_hw_av1_dec.c | 2280 +++++++++ .../verisilicon/rockchip_vpu981_regs.h | 477 ++ .../platform/verisilicon/rockchip_vpu_hw.c | 116 + 14 files changed, 8291 insertions(+) create mode 100644 drivers/media/platform/verisilicon/rockchip_av1_entropymode.c create mode 100644 drivers/media/platform/verisilicon/rockchip_av1_entropymode.h create mode 100644 drivers/media/platform/verisilicon/rockchip_av1_filmgrain.c create mode 100644 drivers/media/platform/verisilicon/rockchip_av1_filmgrain.h create mode 100644 drivers/media/platform/verisilicon/rockchip_vpu981_hw_av1_dec.c create mode 100644 drivers/media/platform/verisilicon/rockchip_vpu981_regs.h -- 2.34.1
