My recent RK3588 kernel adventure:
- dual-core H.265 (HEVC) encoding working live at full 4K@60 on armbian-build edge kernel (6.19-rc8) for Rock 5B[+] and Orange Pi 5 Ultra.
- fix for setting HDMIRX EDID (this didn't work in mainline on any of my tested hardware)
This is out-of-tree (practical focus over upstream goals), but it's stable and producing clean bitstreams.
