This series implement AV1 stateless decoder for RK3588 SoC. The hardware 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, NV12_10LE40_4L4, NV12 and P010 pixels formats. Even if Rockchip have named the hardware VPU981 it looks like a VC9000 but with a different registers mapping. It is based on Daniel's "[PATCH v4] media: Add AV1 uAPI" [1] patches and Sebastian's device-tree patches for RK3588. The full branch can be found here: https://gitlab.collabora.com/linux/for-upstream/-/commits/rk3588_av1_decoder_v2 Fluster score is: 200/239 while testing AV1-TEST-VECTORS with GStreamer-AV1-V4L2SL-Gst1.0. The failing tests are: - the 2 tests with 2 spatial layers: few errors in luma/chroma values - tests with resolution < hardware limit (64x64) - 10bits film grain test: bad macroblocks while decoding, the same 8bits test is working fine. Changes in v2: - Remove useless +1 in sbs computation. - Describe NV12_10LE40_4L4 pixels format. - Post-processor could generate P010. - Fix comments done on v1. - The last patch make sure that only post-processed formats are used when film grain feature is enabled.
