AMD HD 7790 GPU initialization failed?

Banana PI RISC-V Design BPI-F3/BPI-CM6(SpacemiT K1)

Hello. I have Bianbu 2.1.1 OS and connected an HD 7790 GPU with a mini PCIe to PCIe adapter. The GPU is recognized by the system (I can see it in lspci) and radeon tries to initialize, but fails.

It fails with the error number -12 (ENOMEM). The message right before failure is “RAM width 128bits DDR” (from function radeon_bo_init). Afterwards the error “Fatal error during GPU init” appears. This is all from dmesg.

Any ideas for fixing this?

i do not think bianbu 2.1.1 is running kernel 6.10 . iirc it was 6.8. i tried with 5450 - nothing but cursor worked.
