The nodes of Origin, Onyx, Fuel and Tezro systems can be configured |
|
in either N-Modes which allows for more nodes or M-Mode which allows |
|
for more memory. Your hardware is almost certainly running in |
|
M-Mode, so choose M-mode here. |

Change the way a Linux kernel is loaded into memory on a MIPS64 |
|
machine. This is required in order to support text replication on |
|
NUMA. If you need to understand it, read the source code. |

Say Y here to enable replicating the kernel text across multiple |
|
nodes in a NUMA cluster. This trades memory for speed. |
