      rapidio/tsi721_dma: rework scatter-gather list handling · 50835e97
      Alexandre Bounine 提交于
      Rework Tsi721 RapidIO DMA engine support to allow handling data
      scatter/gather lists longer than number of hardware buffer descriptors in
      the DMA channel's descriptor list.
      
      The current implementation of Tsi721 DMA transfers requires that number of
      entries in a scatter/gather list provided by a caller of
      dmaengine_prep_rio_sg() should not exceed number of allocated hardware
      buffer descriptors.
      
      This patch removes the limitation by processing long scatter/gather lists
      by sections that can be transferred using hardware descriptor ring of
      configured size.  It also introduces a module parameter
      "dma_desc_per_channel" to allow run-time configuration of Tsi721 hardware
      buffer descriptor rings.

      rapidio: add new RapidIO DMA interface routines · 4aff1ce7
      Alexandre Bounine 提交于
      Add RapidIO DMA interface routines that directly use reference to the mport
      device object and/or target device destination ID as parameters.
      This allows to perform RapidIO DMA transfer requests by modules that do not
      have an access to the RapidIO device list.
