Matt, Welcome back to the ppc mailing list. I would like your answer to my question really bad on the topic of mapping the PCI bus DMA address to the PLB address space for setting up the 440GP DMA. I don't have the email I sent you anymore.
On one of your response email to me, you said the 440GP maps PCI<->PLB 1:1 and I can use the PCI bus address directly as a PLB address to program the 440GP DMA controller. The thing is that the DMA high and low register only allows 36-bit programming whereas the PCI bus address given to me by the Host is 64-bit. Don't I have to manually setup the PCI-PLB mapping before I can program the DMA controller? OR the 440 kernel has already handle that? Your comment and response are very important and appreciated... Thanks again, --Khai ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
