Recently I’ve been following progress on support for the Rockchip RK3588 System-on-Chip in mainline Linux. I have been using a RockPRO64 single-board computer based on Rockchip’s previous top-end SoC RK3399 for several years as a media centre running Kodi, on Debian with a mainline Linux kernel (plus some patches for improved multimedia support from the LibreELEC project). I’ve been pretty satisfied with the support for RK3399 in mainline Linux, as opposed to a vendor BSP based on an old kernel like 4. Read More...
