Thank you. The thing is one of the input arguments of this function is device_t. How can I get this struct by device name so I can pass it to pci_get_vpd_readonly function? Consider that I'm trying to read em's vpd, how can get em's related device_t struct by it's name? Something like: device_t get_device_by_name(char dev_name) On Monday, January 13, 2014 11:49 PM, John Baldwin <jhb@freebsd.org> wrote: On Sunday, January 12, 2014 3:32:25 am Nomad Esst wrote: >> Hi list >> Any experiences on how to do so?
