Minidriver - Memory allocation

Hi all,

Any body, please clarify some doubts regarding WDM
streaming.

  1. Is it possible to allocate a memory in minidriver and pass it to
    Stream Class driver, instead of using stream class driver allocated
    memory?

Because my target is a PCI Device. It contiguously DMA the data to host
buffer ie.minidriver allocated memory(double buffer scheme). I want to
pass this buffer address to Stream Class Driver. Is it possible? Pls
clarify.

Thanks in advance,
R.Renganathan.
