Mappings are done with vaddr=paddr. - I/O space mapped with two gigapages - Kernel space mapped to statically allocated page tables. 2MB of kernel memory is supported. - Page pool is mapped to the kernel space, to allow virtual memory access for the kernel e.g. to initialize the page memory when it is allocated.
