...n issue on arm is that the pci memory window is too narrow to allocate all the BARs. Can you see if there are messages in the kernel to that effect? All the BAR allocations seem to succeed except for the IO one. AIUI I/O is deprecated, but is it still used on these cards?

Hi Seeing as we (Raspberry Pi) have just launched the Compute Module 4 with an exposed PCIe x1 lane, people are asking about adding graphics cards. Seeing as you are the people who have the knowledge with regard to NVidia and nouveau, what are your immediate thoughts of nouveau working on ARM/ARM64? Is there a chance of this working? I'm no PCIe expert, although I can call on some expertise
