Should I expect > this code to work, or is it not yet working for the mips platform? I've encountered a similar problem on O2. You can probably fix it by adding the code for handling pages in pci_map_sg/pci_unmap_sg/pci_sync_sg. This is what I've done for ip32 and ip27: unsigned long address; if(sg->address) address = sg->address; else address = page_address(sg->page) + sg->offset; dma_cache_wback_inv(address, sg->length); regards, Vivien Chappelier.
