Common buffer DMA will work slightly differently. - - For common buffer DMA, the general technique would be DPC schedules - processing with KsPinAttemptProcessing. The processing routine grabs - the leading edge, copies data out of the common buffer and advances. - Cloning would not be necessary with this technique.
