4 | # This options adds support for userspace processes upto 16TB size. | |

11 | The nodes of Origin 200, Origin 2000 and Onyx 2 systems can be | |
12 | configured in either N-Modes which allows for more nodes or M-Mode | |
13 | which allows for more memory. Your system is most probably | |
14 | running in M-Mode, so you should say N here. | |

16 | config MAPPED_KERNEL |
17 | bool "Mapped kernel support" | |
18 | depends on SGI_IP27 | |
19 | help | |
20 | Change the way a Linux kernel is loaded into memory on a MIPS64 | |
21 | machine. This is required in order to support text replication and | |
22 | NUMA. If you need to understand it, read the source code. | |

24 | config REPLICATE_KTEXT | |
25 | bool "Kernel text replication support" | |
26 | depends on SGI_IP27 | |
27 | help | |
28 | Say Y here to enable replicating the kernel text across multiple | |
29 | nodes in a NUMA cluster. This trades memory for speed. | |

31 | config REPLICATE_EXHANDLERS | |
32 | bool "Exception handler replication support" | |
33 | depends on SGI_IP27 | |
34 | help | |
35 | Say Y here to enable replicating the kernel exception handlers | |
36 | across multiple nodes in a NUMA cluster. This trades memory for | |
37 | speed. |
