Howdy, What are the things to do to use the TLB for access to otherwize unreachable PCI memory or IO areas? I have used the function add_wired_entry to add an entry to the TLB, modified the functions virt_to_phys, phys_to_virt, virt_to_bus, bus_to_virt, and ioremap to do the translations I want , but I wonder if there are other things to do to get this working. Even more so, because none of the mips boards currently in the tree seem to need TLB remapping. Greetz, Tom
