RK3576 Armsom Sige5 - Panfrost GPU Not Working Despite Recent Build Fix

[Mallikarjun Modi]

Hello,
 

I am trying to enable Panfrost GPU acceleration on a new Armsom Sige5 board running the latest edge kernel (6.1.115), but glxinfo -B still shows llvmpipe.
 

I have been troubleshooting this for some time and have discovered that the kernel module (panfrost.ko) loads correctly with modprobe, but it is not binding to the GPU hardware on boot.
 

I believe I have found the reason why. A recent commit to the Armbian build system (https://github.com/armbian/build/commit/836def3d11699537e6289dedfbc766c2050d422d) changes the method for enabling Panfrost. It removes the panfrost overlay and adds KERNEL_TARGET_CONFIG="panfrost-all" instead.
 

It appears that the current edge kernel available through armbian-config does not yet include this essential fix.
 

Can you please advise when a kernel with this change will be available for download, or if there is a manual way I can apply this fix?
 

Thank you.

@Igor is probably in the best position to answer when a new image for your board might be available.

This is actually fairly easy to do by building your own image: "git clone https://github.com/armbian/build.git;cd build;./compile.sh"

This is severely outdated. Use this one instead: https://docs.armbian.com/Developer-Guide_Build-Preparation/

edge = 6.16.y

vendor = 6.1.115

Which kernel do you actually use?

Also isn't panthor the backported gpu driver for rk35xx?
