Oh, don't forget to make : static char bdf_str[1024];
Anywhere in the nic_uio.c file, so this way the other methods can check the content :-) And remove the local declaration from nic_uio_load. -----Mensagem original----- De: dev [mailto:dev-bounces at dpdk.org] Em nome de Fred Pedrisa Enviada em: quarta-feira, 26 de mar?o de 2014 04:22 Para: 'Masaru Oki' Cc: dev at dpdk.org Assunto: [dpdk-dev] RES: RES: hw.nic_uio.bdfs Hello, Here is my fix for probe code : static int nic_uio_probe (device_t dev) { int i, len; char *remaining; long bus = 0, device = 0, function = 0; remaining = bdf_str; len = strlen(remaining); for (i = 0; remaining && len >= 5 && i < len;i+=6) { if ( remaining[i + 1] == ':' && remaining[i + 3] == ':' ) { bus = strtol(&remaining[i + 0],NULL,0); device = strtol(&remaining[i + 2],NULL,0); function = strtol(&remaining[i + 4],NULL,0); if (dev != NULL) { if (pci_get_bus(dev) == bus && pci_get_slot(dev) == device && pci_get_function(dev) == function) { printf("nic_uio: success blocking probe of : %ld:%ld:%ld!\n", bus, device, function); return (ENXIO); } } } } for (i = 0; i < NUM_DEVICES; i++) if (pci_get_vendor(dev) == devices[i].vend && pci_get_device(dev) == devices[i].dev) { device_set_desc(dev, "Intel(R) DPDK PCI Device"); return (BUS_PROBE_SPECIFIC); } return (ENXIO); } Now it is working as intended ;) -----Mensagem original----- De: dev [mailto:dev-bounces at dpdk.org] Em nome de Fred Pedrisa Enviada em: quarta-feira, 26 de mar?o de 2014 04:16 Para: 'Masaru Oki' Cc: dev at dpdk.org Assunto: [dpdk-dev] RES: hw.nic_uio.bdfs Hello, Yes, I am writing a fix for this too ;) De: Masaru Oki [mailto:m-oki at stratosphere.co.jp] Enviada em: quarta-feira, 26 de mar?o de 2014 04:08 Para: Fred Pedrisa Cc: dev at dpdk.org Assunto: Re: [dpdk-dev] hw.nic_uio.bdfs > By default nic_uio takes all the NICs for itself Yes.

But kldunload nic_uio only detach uio driver, don't re-attach kernel driver.
