Hi All, How do I convert a DMA buffer address to its respective virtual address in Linux PPC world?
I am not finding appropriate functions to do that? How are people doing it on PPC platforms? What I trying to do: This is for MCC i.e. Buffer Desc and buffer are in main memory (DMA memory) I have submitted some DMA buffer from a chunk of memory to Device. Now at the end of successful receive, where I know the DMA address by reading from the buffer Descriptors. Now from this DMA address, how do I find out the Virtual address so that I can perform a read on that buffer? Regards, Mukund Jampala
