Which tag shoud I use for rock pi 4b

[markhsumark]

Hi, I am a student researching TrustZone with a keen interest in integrating GPU functionality within TrustZone environments.

I’m looking for a Linux kernel for the Rock Pi 4B to replace the existing Linux kernel in the OP-TEE project. I would like to know which branch or tag would be most suitable and stable.

Thanks.

Would like to get the same answer for my rock-pi-4b-plus.

If you use bsp to build the kernel for Rock Pi 4B+, it builds the branch linux-5.10-gen-rkr3.4
There is no other kernel for this board. Although version 6 might work, it lacks a lot of basic features on this board (e.g. DSI etc.)
