Edit Reason: GPU library packages
)
GPU firmware loading fails on armbian:
This is probably a first step in having GPU support in Xorg and Wayland.
Apply this kernel patch
Configure the gpu driver as a module
Rebuild the kernel and modules and install them.
The driver needs to be compiled as a kernel module. Unsophisticated guess: that moves out the initialization of the gpu from initrd into systemd-land. That is why the firmware does not need to be in initrd but can reside on the /-filesystem.
The two firmware blobs rgx.fw.36.50.54.182 rgx.sh.36.50.54.182 need to be moved into /lib/firmware/ directory. They come from starfive-'s github repro https://media.githubusercontent.com/medi...866.tar.gz
A reboot shows successful firmware load
Th next step in having GPU support in Xorg and Wayland is probably installing the libs, bin, and headers from said img-gpu-powervr-bin-1.17.6210866.tar.gz "[this] is a GPU library packages from Imagination and provide GPU firmware, libOpenCL, vulkan, gles2, gles3. This library is not open source, only provide with binary library." I have not tried that.
