Octeon PCI mapping has to be established to cover the bounce buffers,

Why can't you use swiotlb_init_with_tbl() instead?


Yes, as pointed out be several people, that would be better.

The swiotlb_init_with_tbl() didn't exist in earlier kernel versions andthis simplification was missed when I forward ported the patch set.

By using this function, I think the entire patch set will be MIPSspecific, making it unnecessary to touch the generic swiotlb code.


Thanks,
