Hello, > Well, bus_alloc_resource() will allocate resources for the BAR and update the > BAR for you, the question is if you need to hardcode the range to > bus_alloc_resource() or not. It is necessary for a pci device to set the BAR, if the device would use memory or I/O space, isn't it? I don't know why the BAR is not settable, but I think it is disabled by some reasons and the BAR may be settable if the device could be enabled. If the device have default I/O space, it needs to hardcode the range or isa attach code. The device dose not seem to have default I/O space. This problem is not so important for myself, but it is a good if it was solved. -- KAHO Toshikazu
