1#config SGI_SN0_XXL
2#	bool "IP27 XXL"
3#	depends on SGI_IP27
4#	  This options adds support for userspace processes upto 16TB size.
5#	  Normally the limit is just .5TB.

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

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

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

52	  across multiple nodes in a NUMA cluster. This trades memory for
53	  speed.
