I too am interested in this, for exactly the same reasons. I've asked how to trigger a rescan when a device's resource needs change (e.g. an FPGA becoming programmed and gaining new BAR resources), and the only response I got... well, it was rather rude, and completely unhelpful. I'd suggest there really should be a FAQ for this in the kernel! -- 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
