Hi All,

How do I convert a DMA buffer to virtual address on Linux PPC?

I know there is some thing like dma_to_virt(), but I don't think if there is
one for PPC.
In this scenario where I have submitted some dma buffer form a chunk of
memory to Device.
Now at the end of successful receive, how do I convert it back to Virtual
address?
Any pointers?

Regards,
Mukund Jampala
