The current LE AML devs working at a mainline Linux (aka latest Kernel) and an proper standard implementation at Kodi for S905 that don't require a ton of special fixes. Basically RPi driver quality for AML.
CE devs working at the legacy Kernel (3.14) version that reaching his dead end with Kodi 18. With >= Kodi 19 that driver is not usable anymore and the old 3.14 Kernel etc doesn't allow the new implementation.
Normally nobody would need or use the 3.14 Kernel BUT currently the mainline Linux drivers etc are not yet ready (same story like Rockchip etc). So we could focus to improve an dead horse or focus at the future.
Some devs wanted to improve the legacy version to the max (that requires a ton of special quirks) and the majority wanted to go for the future.
You have the choice between working today and dead tomorrow or not working today but ready for the future.
Both ways have their raison d'être.
where is latest kernel libreelec (s905x based) links for test?
