It looks like the card can support pseudo-DMA, and can * handle converting between the 5380's 8-bit data bus and the 16-bit * podule bus in the process. We support none of this cleverness. * * This card has to be polled: it doesn't have anything connected to * PIRQ*. This seems to be a common failing of Archimedes disc * controllers. */ #include __KERNEL_RCSID(0, "$NetBSD: oak.c,v 1.6 2001/11/13 07:23:16 lukem Exp $"); #include #include #include #include #include #include #include #include #include #include #include #include #include #include void oak_attach (struct device *, struct device *, void *); int oak_match (struct device *, struct cfdata *, void *); /* * Oak SCSI 1 softc structure. * * Contains the generic ncr5380 device node, podule information and * global information required by the driver. */ struct oak_softc { struct ncr5380_softc sc_ncr5380; }; struct cfattach oak_ca = { sizeof(struct oak_softc), oak_match, oak_attach }; /* * Card probe function * * Just match the manufacturer and podule ID's */ int oak_match(struct device *parent, struct cfdata *cf, void *aux) { struct podulebus_attach_args *pa = aux; if (matchpodule(pa, MANUFACTURER_OAK, PODULE_OAK_SCSI, -1)) return 1; /* PowerROM */ if (pa->pa_product == PODULE_ALSYSTEMS_SCSI && podulebus_initloader(pa) == 0 && podloader_callloader(pa, 0, 0) == PRID_OAK_SCSI1) return 1; return 0; } /* * Card attach function * */ void oak_attach(struct device *parent, struct device *self, void *aux) { struct oak_softc *sc = (struct oak_softc *)self; struct podulebus_attach_args *pa = aux; u_char *iobase; char hi_option[sizeof(sc->sc_ncr5380.sc_dev.dv_xname) + 8]; sc->sc_ncr5380.sc_flags |= NCR5380_FORCE_POLLING; sc->sc_ncr5380.sc_min_dma_len = 0; sc->sc_ncr5380.sc_no_disconnect = 0xff; sc->sc_ncr5380.sc_parity_disable = 0xff; sc->sc_ncr5380.sc_dma_alloc = NULL; sc->sc_ncr5380.sc_dma_free = NULL; sc->sc_ncr5380.sc_dma_poll = NULL; sc->sc_ncr5380.sc_dma_setup = NULL; sc->sc_ncr5380.sc_dma_start = NULL; sc->sc_ncr5380.sc_dma_eop = NULL; sc->sc_ncr5380.sc_dma_stop = NULL; sc->sc_ncr5380.sc_intr_on = NULL; sc->sc_ncr5380.sc_intr_off = NULL; #ifdef NCR5380_USE_BUS_SPACE sc->sc_ncr5380.sc_regt = pa->pa_mod_t; bus_space_map(sc->sc_ncr5380.sc_regt, pa->pa_mod_base, 8, 0, &sc->sc_ncr5380.sc_regh); sc->sc_ncr5380.sci_r0 = 0; sc->sc_ncr5380.sci_r1 = 1; sc->sc_ncr5380.sci_r2 = 2; sc->sc_ncr5380.sci_r3 = 3; sc->sc_ncr5380.sci_r4 = 4; sc->sc_ncr5380.sci_r5 = 5; sc->sc_ncr5380.sci_r6 = 6; sc->sc_ncr5380.sci_r7 = 7; #else iobase = (u_char *)pa->pa_mod_base; sc->sc_ncr5380.sci_r0 = iobase + 0; sc->sc_ncr5380.sci_r1 = iobase + 4; sc->sc_ncr5380.sci_r2 = iobase + 8; sc->sc_ncr5380.sci_r3 = iobase + 12; sc->sc_ncr5380.sci_r4 = iobase + 16; sc->sc_ncr5380.sci_r5 = iobase + 20; sc->sc_ncr5380.sci_r6 = iobase + 24; sc->sc_ncr5380.sci_r7 = iobase + 28; #endif sc->sc_ncr5380.sc_rev = NCR_VARIANT_NCR5380; sc->sc_ncr5380.sc_pio_in = ncr5380_pio_in; sc->sc_ncr5380.sc_pio_out = ncr5380_pio_out; /* Provide an override for the host id */ sc->sc_ncr5380.sc_channel.chan_id = 7; sprintf(hi_option, "%s.hostid", sc->sc_ncr5380.sc_dev.dv_xname); (void)get_bootconf_option(boot_args, hi_option, BOOTOPT_TYPE_INT, &sc->sc_ncr5380.sc_channel.chan_id); sc->sc_ncr5380.sc_adapter.adapt_minphys = minphys; printf(": host=%d, using 8 bit PIO\n", sc->sc_ncr5380.sc_channel.chan_id); ncr5380_attach(&sc->sc_ncr5380); }
