I found and resolved some faults in RockChip MPP and RockChip kernel 4.4. RockChip ignored any requests (see mpp#38 and kernel#61 ...) so I stopped my development/troubleshooting of HDR pipe and any other RockChip code. MPV/Kodi are probably still blocked (kwiboo#22, kwiboo#24). RockChip marketing still say "4k60 4:4:4" (TMDS 594MHz) but limited in code (TMDS 371MHz, eg. 4k60 yuv420p10le) and true output has limits (TMDS 297MHz) on Rock64 with RockChip 4.4 linux

I left this community in Aug 2019 due to PINE64 refusal to produce/deliver ROCK64-1G version 3 after more than one year of changing statuses to "planning", "evaluating", "releasing", "availability", "estimated availability" and finally "no schedule" 
. ROCK64 is dead platform without any advantage. Buy Raspberry PI 4 !
