Hi,
I'm trying to update the ar(4) device driver to also understand the Digi
SYNC/570i-PCI cards, but found a little problem. According to the docs
for the card it has 4 pci maps, but FreeBSD only see 3 of them. I have
tried it in another machine with a different motherboard and BIOS, but
the result is the same, although the addresses differ.
Here is what the pci probe code with verbose on says:
--------------------
found-> vendor=0x114f, dev=0x5012, revid=0x00
class=07-80-00, hdrtype=0x00, mfdev=0
intpin=a, irq=10
map[0]: type 1, range 32, base fed7fc00, size 7
map[1]: type 4, range 32, base 0000fc00, size 7
map[2]: type 1, range 32, base fed80000, size 19
--------------------
I have tried the DOS diagnostic utility that came with the card and that
works fine. What is interresting is that according to the diagnostic
utility the base for map[0] is a little different: 0xfedc1000. The base
for map[3] according to it is: 0xfedc0000.
Do anybody have an idea what is happening or how I can resolve it? If
I understand correctly the BIOS do the mapping and FreeBSD only read
and use it? Is that correct? In the mean time I'll start to read the
pci code and see if I can figure out where the problem is.
This is on 3.0-CURRENT. I don't have a 2.2.x machine at the moment to see
if it behaves the same. Attached below is the output of a verbose boot.
John
