Yes mapping was never an issue. Contiguous physical frames is an issue. kmalloc limitation is 128KB. __get_page_frames with order higher that 10 would have higher chances of failing. I guess I need to grab as much contiguous memory as possible during boot time. My /proc/buddyinfo on a 512MB RAM machine paints a depressing picture of contiguous chunks. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
