I have an issue trying to make any pci-e devices work with vanilla 5.10.108 kernel. I’ve found a lot of issues connected with pci-e on BPI-R64 but I cannot understand which one do I have). Facts that I know:
lspcishows absolutely nothing, even host/pci bridges
- there is no interesting messages about pci on dmesg:
[[email protected]:~]$ dmesg | grep -i pci [ 0.859860] PCI: CLS 0 bytes, default 64 [ 2.208226] ehci-pci: EHCI PCI platform driver [ 2.208619] ohci-pci: OHCI PCI platform driver
- it seems pci works fine with frank’s debian image with almost the same kernel 5.10.0 (downloaded it from here [BPI-R64] debian buster with new bootchain and linux 5.10)
How can I find out what goes wrong and how to fix it? What should I check first? Maybe there is some obvious patches/config options that should be enabled?
