This uses the Rockchip RK3588 SoC with an ARM Mali-G610 GPU. In general, that's a nice chip. My concerns are - are there open source (Linux) drivers for that

This uses the Rockchip RK3588 SoC with an ARM Mali-G610 GPU. In general, that's a nice chip. My concerns are - are there open source (Linux) drivers for that GPU available now? - is this CPU really suited for battery-powered mobile applications? I couldn't find details on the power consumption right away...
