With the current setup of that file that's going to be pretty hard to do. I have a small Python script that does the generation of that file for me (though its primitive and has some errors). Not really sure how to correlate vendor ID and device ID together. The script, as I wrote it, is below:Octocontrabass wrote:Yes.Ethin wrote:How would I determine this at runtime? Would I just mask all the bits anyway?
But get_device_string() tries to identify the device using only the device ID, which means it will be wrong if more than one vendor assigns the same device ID. It needs to work like get_subclass_string(), taking both the vendor ID and the device ID as input.Ethin wrote:I get this information by calling get_vendor_string(), get_device_string(), and get_class_string(), all of which are defined in src/pcidb.rs. Its a rust implementation of the entire PCI ID database.
