Hello, I want to transfer data directly from one PCIe device to another. Is there a generic way to retrieve the bus address of a PCI IO memory region? If I understand "Linux Device Drivers" correct, then pci_resource_start() returns some address that I can then map into the kernel space with ioremap() and access like local memory. But what kind of address is pci_resource_start() returning? Is it a bus address that I could directly hand to another PCI device as a target address, or is it something else? Thanks, -Nikolaus -- ÂTime flies like an arrow, fruit flies like a Banana. PGP fingerprint: 5B93 61F8 4EA2 E279 ABF6 02CF A9AD B7F8 AE4E 425C -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
