Content-Type: text/plain; charset=us-ascii Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: I have a silly doubt about the pci-dma interface . Is there any relevance of pci-dma interface on a 32 bit plateform? (though i understand its relevance on 64 bit plateform) also in DMA-MAPPING.txt written that drivers using this interface , should no more use virt_to_bus and like stuffs. what is the special significance of this? Is it somewhere related to snooping during DMA (as part of cache consistency protocol) ? If anyone can explain this briefly , it will be much helpful.
