Hi Warner,
I'm trying to get my Realport working with if_xe.c. I've got the cem56fix
re-written (it was actually easy) and the driver dances around abit trying to
find a phy but doesn't actually get one.
I think that the problem is in the IO space allocation in xe_activate. In
cem56fix the IO address is written to a register on the card
old:
xe_memwrite( scp->dev, DINGO_EBAR0, ioport & 0xff );
xe_memwrite( scp->dev, DINGO_EBAR1, (ioport >> 8) & 0xff );
my re-write:
bus_space_write_1(bst, bsh, DINGO_EBAR0, ioport & 0xff);
bus_space_write_1(bst, bsh, DINGO_EBAR1, (ioport >> 8) & 0xff);
However, EBAR0 always has bits 3:0 set to 0. I need a 16bit aligned io port
from xe_activate. How do I do it?
Thanks
Duncan
