It combines the original codec work done by Maxime Jourdan in 2019 [0] and improvements by Benjamin Roszak in 2021 [1]. Only GXBB/GXL/GXM are enabled as decoding currently crashes on G12A and later SoCs when trying to decode a 10-bit HEVC stream. The goal of upstreaming the driver in its current state is to encourage greater community contribution towards adding missing features, and fixing the bugs and conformance issues necessary to get out of staging. The HEVC codec presented here is generally partnered with FFMpeg sources that are being maintained by the Raspberry Pi Foundation [2] and [3] that contain numerous improvements to v4l2_m2m (and v4l2_request) support. There is active work in progress to refine the changeset and send it upstream.
