[Gc-linux-devel] Re: dvd kernelmodule: memory address problem

[JockyW <joc...@ho...>]

Of course i have read that :) I didn't write it but I align the address
before i pass it to the DMA address reg (same for length).

Problem is that the DMA regs take only 26 bits (b0-b25) with b0-b4 all zero.
My address is 32 bits so should I simply strip 6 bits off? I have the
feeling that the address has to be remapped to some kind of bus address. But
I have no idea how.
