As discussed on IRC, whenever we enable H.264 and HEVC on VC9000 cores, we will benefit from sharing some very specific code with the G1 and G2 (respectively). Though for now, there is no overlap as the single core on RK3588 have all other codecs disabled by fuse. > > Thanks! > Ezequiel > > > The full branch can be found here: > > https://gitlab.collabora.com/linux/for-upstream/-/commits/rk3588_av1_decoder_v1 > > > > Fluster score is: 151/239 while testing AV1-TEST-VECTORS with GStreamer-AV1-V4L2SL-Gst1.0. > > 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 > >
