I have tested this on my AMD Overdrive so Tested-by: Graeme Gregory <graeme.gregory@xxxxxxxxxx> But to actually get my r8169 network card working I also need the following patch. diff --git a/drivers/pci/probe.c b/drivers/pci/probe.c index 2fbf840..40e24e2 100644 --- a/drivers/pci/probe.c +++ b/drivers/pci/probe.c @@ -1717,7 +1717,7 @@ void pci_device_add(struct pci_dev *dev, struct pci_bus *bus) set_dev_node(&dev->dev, pcibus_to_node(bus)); dev->dev.dma_mask = &dev->dma_mask; dev->dev.dma_parms = &dev->dma_parms; - dev->dev.coherent_dma_mask = 0xffffffffull; + dev->dev.coherent_dma_mask = DMA_BIT_MASK(64); pci_dma_configure(dev); pci_set_dma_max_seg_size(dev, 65536); I suspect we need to set coherent_dma_mask somewhere in the platform but I do not know where this should happen. Hopefully an ARM64 expert can help.
