Hi folks, I've got a problem doing DMA over the PCI bus. After I've done a DMA write to the device, the kernel hangs when I do a pci_read_config_byte for that device. I've determined that when pci_read_config_byte is called, execution makes it to the call to the read_byte function of the pci_ops structure. (This function is pointed to by pdev->bus->ops->read_byte.) What I can't seem to find is the code that is actually doing the read from the device configuration space. Can somebody point me to it? This is on a 405GP Walnut board.
Thanks, Jim ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
