uio and DMA memory allocations

[Gleb Natapov]

Hi Hans,

   Will it be possible to allocate DMAable memory using uio framework
(currently it isn't as far as I see).  More specifically if a driver needs
memory allocated with dma_alloc_coherent() will it be possible to allocate
it and map into userspace using uio?
