| 10 | help |
| 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 ARCH_DISCONTIGMEM_ENABLE |
| 17 | bool |

| 19 | help |
| 20 | Say Y to upport efficient handling of discontiguous physical memory, |
| 21 | for architectures which are either NUMA (Non-Uniform Memory Access) |
| 22 | or have huge holes in the physical address space for other reasons. |
| 23 | See <file:Documentation/vm/numa> for more. |

| 25 | config NUMA |
| 26 | bool "NUMA Support" |
| 27 | depends on SGI_IP27 |
| 28 | help |
| 29 | Say Y to compile the kernel to support NUMA (Non-Uniform Memory |
| 30 | Access). This option is for configuring high-end multiprocessor |
| 31 | server machines. If in doubt, say N. |
| 32 | |
| 33 | config MAPPED_KERNEL |
| 34 | bool "Mapped kernel support" |
| 35 | depends on SGI_IP27 |
| 36 | help |
| 37 | Change the way a Linux kernel is loaded into memory on a MIPS64 |
| 38 | machine. This is required in order to support text replication and |
| 39 | NUMA. If you need to understand it, read the source code. |
| 40 | |
| 41 | config REPLICATE_KTEXT |
| 42 | bool "Kernel text replication support" |
| 43 | depends on SGI_IP27 |
| 44 | help |
| 45 | Say Y here to enable replicating the kernel text across multiple |
| 46 | nodes in a NUMA cluster. This trades memory for speed. |
| 47 | |
| 48 | config REPLICATE_EXHANDLERS |
| 49 | bool "Exception handler replication support" |
| 50 | depends on SGI_IP27 |
| 51 | help |
| 52 | Say Y here to enable replicating the kernel exception handlers |
| 53 | across multiple nodes in a NUMA cluster. This trades memory for |
| 54 | speed. |
