Hello.

I want to DMA copy data from Host computer's memory to 

PCI device's memory.(PCI device is IXP1200 Evaluation Board).

Of course, IXP1200 DMA unit can initiate DMA operation.

So I tried to use that unit, but finally I failed to use.

So I want to use host computer(or linux kernel)'s DMA mechanism

to copy data from Host computer's memory to

PCi device's memory.

How can I do that? function? simple instruction?

Please give any advice.

And if above this is complicated, 

please give me method of fast data copy between 2 memories.


Thanks!
