soo.. apparently the broadcom VC4+ GPUs (the ones used in raspberry pis and stuff) do not support format-less image writes, sooo.. supporting OpenCL images in #rusticl on that hardware will be a bit "difficult", because it needs to be handled within the kernel...
I should probably check out how other drivers are handling this, because either I'm missing something here or some other vendors are kinda in the same situation (not for all hardware, probably just older GPUs).
