Hello.
Please tell me how to add code to com_puc_attach() of
sys/dev/puc/com_puc.c from OpenBSD-5.1 so the kernel
can work with the known UART type without device probing?
Perhaps my way is not quite correct, in this case
please tell me which way to go.
void
com_puc_attach(parent, self, aux)
struct device *parent, *self;
void *aux;
{
struct com_softc *sc = (void *)self;
struct puc_attach_args *pa = aux;
const char *intrstr;
/* Grab a PCI interrupt. */
intrstr = pa->intr_string(pa);
sc->sc_ih = pa->intr_establish(pa, IPL_TTY, comintr, sc,
sc->sc_dev.dv_xname);
if (sc->sc_ih == NULL) {
printf(": couldn't establish interrupt");
if (intrstr != NULL)
printf(" at %s", intrstr);
printf("\n");
return;
}
printf(" %s", intrstr);
sc->sc_iot = pa->t;
sc->sc_ioh = pa->h;
sc->sc_iobase = pa->a;
if (PUC_IS_COM_MUL(pa->type))
sc->sc_frequency = COM_FREQ * PUC_COM_GET_MUL(pa->type);
else
sc->sc_frequency = COM_FREQ * (1 << PUC_COM_GET_POW2(pa->type));
+ /* If this is a known card, provide the UART type. */
+ if (PCI_VENDOR(?) == PCI_VENDOR_PLX &&
+ PCI_PRODUCT(?) == PCI_PRODUCT_PLX_CRONYX_OMEGA)
+ sc->sc_uarttype = COM_UART_ST16C654;
com_attach_subr(sc);
}
