    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!
