    SubjectUIO DMA to userspace question
    From
    Hello all,

    can I use the UIO framework for the following?

    The userspace portion of the driver allocates memory in user-space
    using malloc() - usually resulting in a scatter pages in physical
    memory.
    The UIO kernel portion of the driver maps those using pci_map_sg().

    Is this possible, or does the UIO framework assume memory for DMA is
    allocated in kernel space?


    Thanks,
    --
    Leon
