Hello!
Today I ported the dev/ed driver to bus_space_(read|write) instead
of outb/inb/outw/inw.
My PCI card already works. However, I'm having problems with
kvtop(), which is used by the sub-driver for the SMC cards.
This one uses soemthing like:
if (isa16bit) {
if (sc->is790) {
sc->wd_laar_proto = ed_readb(sc,
sc->asic_addr + ED_WD_LAAR);
} else {
sc->wd_laar_proto = ED_WD_LAAR_L16EN |
((kvtop(sc->mem_start) >> 19) & ED_WD_LAAR_ADDRHI);
}
/*
* Enable 16bit access
*/
ed_writeb(sc, sc->asic_addr + ED_WD_LAAR, sc->wd_laar_proto |
ED_WD_LAAR_M16EN);
sc->mem_start is set to the virtual address of the memory:
if_ed.c: sc->mem_start = (caddr_t) rman_get_virtual(sc->mem_res);
However, I tried to find a replacement myself, but couldn't find
anything that could replace the call to kvtop() here.
On the other hand, I could imagine that rman_get_start w/o the usage
of kvtop() could be enough here.
Could anyone point me to the right direction please?
Thanks
Alex
