CH368 pcie to local bus
on rockpi 4 it fails due problems with designware pcie ip core
board on aliexpress there is plenty of them there
If you have one then provide the full output from lspci -vvv. A fair amount can be deduced from that without having to buy one.
from my x86 box, module loaded is uio_pci_generic.

I/O regions seem to be an x86 specific thing, so it depends on what the card and uio_pci_generic need to do with them. It's not obvious from a quick read of the driver.
it is for backward compatibility, usually for x86
as i'm not experienced 'chinese speeker/reader' it is not easy to understand ch368 manual which is only in chinese. so for now i just put card in, without configuration.
anyway uio pci driver is goal for me even on arm
