NICs * using the Tigon may have anywhere from 512K to 2MB of SRAM. The * Tigon supports hardware IP, TCP and UCP checksumming, multicast * filtering and jumbo (9014 byte) frames. The hardware is largely * controlled by firmware, which must be loaded into the NIC during * initialization. * * The Tigon 2 contains 2 R4000 CPUs and requires a newer firmware * revision, which supports new features such as extended commands, * extended jumbo receive ring descriptors and a mini receive ring. * * Alteon Networks is to be commended for releasing such a vast amount * of development material for the Tigon NIC without requiring an NDA * (although they really should have done it a long time ago). With * any luck, the other vendors will finally wise up and follow Alteon's * stellar example. * * The following people deserve special thanks: * - Terry Murphy of 3Com, for providing a 3c985 Tigon 1 board * for testing * - Raymond Lee of Netgear, for providing a pair of Netgear * GA620 Tigon 2 boards for testing * - Ulf Zimmermann, for bringing the GA260 to my attention and * convincing me to write this driver. * - Andrew Gallatin for providing FreeBSD/Alpha support. */ #include <sys/param.h> #include <sys/device.h> #include <sys/systm.h> #include <net/if.h> #include <net/if_media.h> #include <netinet/in.h> #include <netinet/if_ether.h> #include <dev/pci/pcireg.h> #include <dev/pci/pcivar.h> #include <dev/pci/pcidevs.h> #include <dev/ic/tireg.h> #include <dev/ic/tivar.h> int ti_pci_match(struct device *, void *, void *); void ti_pci_attach(struct device *, struct device *, void *); const struct cfattach ti_pci_ca = { sizeof(struct ti_softc), ti_pci_match, ti_pci_attach }; const struct pci_matchid ti_devices[] = { { PCI_VENDOR_NETGEAR, PCI_PRODUCT_NETGEAR_GA620 }, { PCI_VENDOR_NETGEAR, PCI_PRODUCT_NETGEAR_GA620T }, { PCI_VENDOR_ALTEON, PCI_PRODUCT_ALTEON_ACENIC }, { PCI_VENDOR_ALTEON, PCI_PRODUCT_ALTEON_ACENICT }, { PCI_VENDOR_3COM, PCI_PRODUCT_3COM_3C985 }, { PCI_VENDOR_SGI, PCI_PRODUCT_SGI_TIGON }, { PCI_VENDOR_DEC, PCI_PRODUCT_DEC_PN9000SX } }; int ti_pci_match(struct device *parent, void *match, void *aux) { return (pci_matchbyid(aux, ti_devices, nitems(ti_devices))); } void ti_pci_attach(struct device *parent, struct device *self, void *aux) { struct ti_softc *sc = (struct ti_softc *)self; struct pci_attach_args *pa = aux; pci_chipset_tag_t pc = pa->pa_pc; pci_intr_handle_t ih; const char *intrstr = NULL; bus_size_t size; /* * Map control/status registers. */ if (pci_mapreg_map(pa, TI_PCI_LOMEM, PCI_MAPREG_TYPE_MEM | PCI_MAPREG_MEM_TYPE_32BIT, 0, &sc->ti_btag, &sc->ti_bhandle, NULL, &size, 0)) { printf(": can't map registers\n"); return; } sc->sc_dmatag = pa->pa_dmat; if (pci_intr_map(pa, &ih)) { printf(": can't map interrupt\n"); goto unmap; } intrstr = pci_intr_string(pc, ih); sc->ti_intrhand = pci_intr_establish(pc, ih, IPL_NET, ti_intr, sc, self->dv_xname); if (sc->ti_intrhand == NULL) { printf(": can't establish interrupt"); if (intrstr != NULL) printf(" at %s", intrstr); printf("\n"); goto unmap; } printf(": %s", intrstr); /* * We really need a better way to tell a 1000baseTX card * from a 1000baseSX one, since in theory there could be * OEMed 1000baseTX cards from lame vendors who aren't * clever enough to change the PCI ID.
