Looks like the baseline for that is 4.14. The patch that you referenced above was applied to 4.15 and is not part of that Toradex patchset either, so... > I get the following messages in dmesg: > [ 4.913881] pci 0000:01:00.0: [8086:157b] type 10 class 0x020000 > [ 4.913913] pci 0000:01:00.0: unknown header type 10, ignoring device > > After removing the changes from the patch https://patchwork.kernel.org/patch/ > 9967399/ > --------- > > > +} > > + > > static struct pci_ops tegra_pcie_ops = { > > .add_bus = tegra_pcie_add_bus, > > .remove_bus = tegra_pcie_remove_bus, > > .map_bus = tegra_pcie_map_bus, > > - .read = pci_generic_config_read32, > > - .write = pci_generic_config_write32, > > + .read = tegra_pcie_config_read, > > + .write = tegra_pcie_config_write, > > }; > > > > ------ > > the Network Controller work. > So it seems this model has issues with other than 32-bit access. ... I'm not sure how that would be related here. Unless I'm misunder- standing what you're saying. You are saying that if you use pci_generic_config_{read,write}32() for all accesses, that the network controller works for you? And it doesn't work if you use the tegra_pcie_config_{read,write}() functions for accesses? I'd be somewhat surprised if this wasn't working. I'm not aware of any similar reports against the upstream kernel. Have you tried building a recent linux-next, or -rc or something like the latest release (5.1)? Adding Marcel here, perhaps he's encountered a similar issue. Also adding the linux-tegra mailing list for broader visibility.
