RKVDEC2 patches were posted on Friday by Collabora's Detlev Casanova. The initial hardware target with RKVDEC2 is on supporting video decode for Rockchip's RK3588 . The RK3588 SoC pairs a quad-core Arm Cortex-A76 and quad-core Arm Cortex-A55 with a Mali-G610 MC4 graphics, a basic NPU, and video accelerated decode for H.264 / H.265 / AV1 / AVS2.
The RKVDEC2 is being developed since with the newer SoCs is second-generation Rockchip video decode IP. There are dual video decoders on the RK3588 for supporting up to 8K@30 video but with the initial Linux driver only using one video decoder at a time is currently supported. This driver also is initially limited to H.264 even though HEVC/H.265, VP9, AV1, and AVS2 are also supported by the hardware.
The RKVDEC2 driver is based in part on the original RKVDEC driver. Those interested in this second-generation Rockchip video decode driver for Linux can find the initial patches under review on the kernel mailing list . Along with the forthcoming NPU driver, the RK3588 has been seeing a lot of nice upstream driver support work.
