Hello all,
I use FreeBSD-2.1.0R on HP Vectra VL590. and I try to install the network
card 'SMC EtherPowerPCI BT'.
but it could not be recognized. The error message is:
pci_map_port failed: device's iorange 0xff80-0xffff
is incompatible with its bridge's range 0x0-0xffff
But the bridge's iorange '0x0-0xffff' includes the device's iorange
'0xff80-0xffff'. I think the device's iorange is right.
Is it a bug of pci driver ?
I change the driver source code by following and it is working well.
In /usr/src/sys/pci/pci.c:
int pci_map_port (pcici_t tag, u_long reg, u_short* pa)
{
[...]
iosize = -(data & PCI_MAP_IO_ADDRESS_MASK);
if (ioaddr < pcicb->pcicb_iobase
|| ioaddr + iosize > pcicb->pcicb_iolimit) {
~~~~~~~~~~~~~~~~
it should be (ioaddr + iosize - 1)
printf ("pci_map_port failed: device's iorange 0x%x-0x%x "
"is incompatible with its bridge's range 0x%x-0x%x\n",
(unsigned) ioaddr, (unsigned) ioaddr + iosize - 1,
(unsigned) pcicb->pcicb_iobase,
(unsigned) pcicb->pcicb_iolimit);
return (0);
}
[...]
}
